Lanthanum Titanate: AMERICAN ELEMENTS Supplier & Tech Info

Lanthanum Titanate is a semiconductor used in high power, high frequency applications and in laser diodes.American Elements produces to many standard grades when applicable, including Mil Spec (military grade); ACS, Reagent and Technical Grade; Food, Agricultural and Pharmaceutical Grade; Optical Grade, USP and EP/BP (European Pharmacopoeia/British Pharmacopoeia)and follows applicable ASTM testing standards.Typical and custom packaging is available. Additional technical, research and safety (MSDS) information is available as is a Reference Calculator for converting relevant units of measurement.

Lanthanum is a Block F, Group 3, Period 6 element. The number of electrons in each of Lanthanum's shells is 2, 8, 18, 18, 9, 2 and its electronic configuration is [Xe] 5d¹ 6s². In its elemental form lanthanum 's CAS number is 7439-91-0. The lanthanum atom has a radius of 187.pm and it's Van der Waals radius is 200.pm. Lanthanum and compounds of Lanthanum are somewhat toxic. Lanthanum is one of the products manufactured and distributed under the tradename AE Rare Earths . Lanthanum is the first element in the rare earth or lanthanide series. It is the model for all the other trivalent rare earths. After cerium, it is the second most abundant of the rare earths. Lanthanum is available as metal and compounds with purities from 99% to 99.999% (ACS grade to ultra high purity); metals in the form of foil, sputtering target, and rod, and compounds as submicron and nanopowder.Lanthanum-rich lanthanide compositions have been used extensively for cracking reactions in FCC catalysts, especially to manufacture low-octane fuel for heavy crude oil. The name Lanthanum originates from the Greek word Lanthaneia which means 'To lie hidden'. See Lanthanum 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.
