See safety data and research below. American Elements specializes in producing high purity Cerium Titanium Sputtering Targets with the highest possible density and smallest possible average grain sizes for use in semiconductor, chemical vapor deposition (CVD) and physical vapor deposition (PVD) display and optical applications. Our standard Sputtering Targets for thin film are available monoblock or bonded with dimensions and configurations up to 820 mm with hole drill locations and threading, beveling, grooves and backing designed to work with both older sputtering devises as well as the latest process equipment, such as large area coating for solar energy or fuel cells and flip-chip applications. Research sized targets are also produced as well as custom sizes and alloys. All targets are analyzed using best demonstrated techniques including X-Ray Fluorescence (XRF), Glow Discharge Mass Spectrometry (GDMS), and Inductively Coupled Plasma (ICP). "Sputtering" allows for thin film deposition of an ultra high purity sputtering metallic or oxide material onto another solid substrate by the controlled removal and conversion of the target material into a directed gaseous/plasma phase through ionic bombardment. We can also provide targets outside this range in addition to just about any size rectangular, annular, or oval target. Materials are produced using crystallization, solid state and other ultra high purification processes such as sublimation. American Elements specializes in producing custom compositions for commercial and research applications and for new proprietary technologies. American Elements also casts any of the rare earth metals and most other advanced materials into rod, bar or plate form, as well as other machined shapes and through other processes such as nanoparticles (See also application discussion at Nanotechnology Information and at Quantum Dots) and in the form of solutions and organometallics. We also produce Cerium Metal as disc, granules, ingot, pellets, pieces, powder, and rod. Other shapes are available by request.
Cerium is a Block F, Group 3, Period 6 element. The number of electrons in each of Cerium's shells is 2, 8, 18, 19, 9, 2 and its electronic configuration is [Xe]4f2 6s2. In its elemental form cerium's CAS number is 7440-45-1. The cerium atom has a radius of 182.5.pm and it's Van der Waals radius is 181.pm. Cerium is moderately toxic. Cerium is one of the products manufactured and distributed under the tradename AE Rare Earths. Cerium is the most abundant of the rare earths metals. It is characterized chemically by having two valence states , the +3 cerous and +4 ceric states. The ceric state is the only non-trivalent rare earth ion stable in aqueoussolutions.It is, therefore, strongly acidic and moderately toxic. It is also a strong oxidizer.The cerous state closely resembles the other trivalent rare earths. The numerous commercial applications for cerium include metallurgy, glass and glass polishing, ceramics, catalysts, as the electrolyte for solid oxide fuel cells when doped with yttrium, gadolinium or samarium and in phosphors. In steel manufacturing it is used to remove free oxygen and sulfur by forming stable oxysulfides and by tying up undesirable trace elements, such as lead and antimony. It is considered to be the most efficient glass polishing agent for precision optical polishing. It is also used to decolor glass by keeping iron in its ferrous state. The ability of cerium-doped glass to block out ultra violet light is utilized in the manufacturing of medical glassware and aerospace windows. It is also used to prevent polymers from darkening in sunlight and to suppress discoloration of television glass.
Cerium was first discovered by W. von Hisinger in 1903. The element was named after the asteroid Ceres. See Cerium research below.
Titanium is a Block D, Group 4, Period 4 element. The number of electrons in each of Titanium's shells is 2, 8, 10, 2 and its electronic configuration is [Ar] 3d2 4s2. In its elemental form titanium's CAS number is 7440-32-6. The titanium atom has a radius of 144.8.pm and it's Van der Waals radius is 200.pm. Titanium metal is not considered to be toxic although titanium as metal shavings or powder is considered a fire hazard. In its metallic form it is not only very strong and light weight, but also highly resistant to corrosion. Thus it can be found in numerous aerospace and military applications. In its oxide form it used in low grades to produce a white pigment. Titanium is the bases for numerous commercially essential compound groups, such as titanium titanates in electronic and di-electric formulations and in crystal growth for ruby and sapphire lasers. Titanium information, including Technical Data, Safety Data and its high purity properties, research, applications and other useful facts are discussed here. Scientific facts such as the atomic structure, ionization energy , abundance on Earth, conductivity and thermal properties are included. Titanium was first discovered by William Gregor in 1791. Titanium was named after the word Titanos which is Greek for Titans. See Titanium research below. Titanium was named after the word Titanos which is Greek for Titans. See Titanium research below.

Cerium is a Block F, Group 3, Period 6 element. The number of electrons in each of Cerium's shells is 2, 8, 18, 19, 9, 2 and its electronic configuration is [Xe]4f2 6s2. In its elemental form cerium's CAS number is 7440-45-1. The cerium atom has a radius of 182.5.pm and it's Van der Waals radius is 181.pm. Cerium is moderately toxic. Cerium is one of the products manufactured and distributed under the tradename AE Rare Earths. Cerium is the most abundant of the rare earths metals. It is characterized chemically by having two valence states , the +3 cerous and +4 ceric states. The ceric state is the only non-trivalent rare earth ion stable in aqueous
solutions.It is, therefore,
strongly acidic and moderately toxic. It is also a strong oxidizer.The cerous state closely resembles the other trivalent rare earths. The numerous commercial applications for cerium include metallurgy, glass and glass polishing, ceramics, catalysts, as the electrolyte for solid oxide fuel cells when doped with yttrium, gadolinium or samarium and in phosphors. In steel manufacturing it is used to remove free oxygen and sulfur by forming stable oxysulfides and by tying up undesirable trace elements, such as lead and antimony. It is considered to be the most efficient glass polishing agent for precision optical polishing. It is also used to decolor glass by keeping iron in its ferrous state. The ability of cerium-doped glass to block out ultra violet light is utilized in the manufacturing of medical glassware and aerospace windows. It is also used to prevent polymers from darkening in sunlight and to suppress discoloration of television glass.
Cerium was first discovered by W. von Hisinger in 1903. The element was named after the asteroid Ceres. See Cerium research below.
Titanium is a Block D, Group 4, Period 4 element. The number of electrons in each of Titanium's shells is 2, 8, 10, 2 and its electronic configuration is [Ar] 3d2 4s2. In its elemental form titanium's CAS number is 7440-32-6. The titanium atom has a radius of 144.8.pm and it's Van der Waals radius is 200.pm. Titanium metal is not considered to be toxic although titanium as metal shavings or powder is considered a fire hazard. In its metallic form it is not only very strong and light weight, but also highly resistant to corrosion. Thus it can be found in 
numerous aerospace and military applications. In its oxide form it used in low grades to produce a white pigment. Titanium is the bases for numerous commercially essential compound groups, such as 
titanium titanates in electronic and di-electric formulations and in crystal growth for ruby and sapphire lasers. Titanium information, including Technical Data, Safety Data and its high purity properties, research, applications and other useful facts are discussed here. Scientific facts such as the atomic structure, ionization energy , abundance on Earth, conductivity and thermal properties are included. Titanium was first discovered by William Gregor in 1791. Titanium was named after the word Titanos which is Greek for Titans. See Titanium research below. Titanium was named after the word Titanos which is Greek for Titans. See Titanium research below.
