Potassium Titanyle Arsenate is a crystalline solid used in photo optic applications.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.
Potassium is a Block S, Group 1, Period 4 element. The number of electrons in each of Potassium's shells is 2, 8, 8, 1 and its electronic configuration is [Ar] 4s1. In its elemental form potassium's CAS number is 7440-09-7. The potassium atom has a radius of 227.2 .pm and it's Van der Waals radius is 275.pm. Potassium is not toxic. Potassium is the seventh most abundant element on earth. In its metallic form it is one of the most reactive and electropositive of all metals and rapidly oxidizes. As with other metals of the alkali group, the metal decomposes in water with the evolution of hydrogen. It catches fire spontaneously in water. In high purity, potassium compounds have numerous pharmacological, medical, and electronics applications. Important compounds include the hydroxide, nitrate, carbonate, chloride, bromide, iodide, and sulfate. Lower purity compounds are used in pyrotechnics for its violet color on ignition and in glass and ceramic glazes to produce this color. Potassium also used as a nutrient in plant growth. Potassium was first discovered by Sir Humphrey Davy in 1807. The origin of the element name comes from the English word 'potash' meaning pot ashes and the Arabic word 'qali' which means alkali. The symbol K originates from the Latin word 'kalium'. See Potassium 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.
Arsenic is a Block P, Group 15, Period 4 element. The number of electrons in each of Arsenic's shells is 2, 8, 18, 5 and its electronic configuration is [Ar] 3d10 4s2 4p3. In its elemental form arsenic's CAS number is 1327-53-3. The arsenic atom has a radius of 124.5.pm and it's Van der Waals radius is 185.pm. Arsenic in the organic form is not harmful but in the inorganic form it is extremely toxic even in very small amounts. Arsenic has numerous applications as a semiconductor and other electronic applications as Indium arsenide, silicon arsenide and tin arsenidea. Arsenic is finding increasing uses as a doping agent in solid-state devices such as transistors. Gallium arsenide is used as a laser material to convert electricity directly into coherent light. Arsenic is used in bronzing and for hardening and improving the sphericity of shot. Arsenic is available as metal and compounds with purities from 99% to 99.9999% (ACS grade to ultra-high purity); metals in the form of foil, sputtering target, and rod, and compounds as submicron and nanopowder. Arsenic 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. See Arsenic research below.

Titanium was named after the word Titanos which is Greek for Titans. See Titanium research below. 
Arsenic is a Block P, Group 15, Period 4 element. The number of electrons in each of Arsenic's shells is 2, 8, 18, 5 and its electronic configuration is [Ar] 3d10 4s2 4p3. In its elemental form arsenic's CAS number is 1327-53-3.
The arsenic atom has a radius of 124.5.pm and it's Van der Waals radius is 185.pm. Arsenic in the organic form is not harmful but in the inorganic form it is extremely toxic even in very small amounts. Arsenic has numerous applications as a semiconductor and other electronic applications as Indium arsenide, silicon arsenide and tin arsenidea. Arsenic is finding increasing uses as a doping agent in solid-state devices such as transistors. Gallium arsenide is used as a laser material to convert electricity directly into coherent light. Arsenic is used in bronzing and for hardening and improving the sphericity of shot.
