Platinum Selenide (PtSe) is a crystal grown product generally immediately available in most volumes. Technical, research and safety (MSDS) information is available as is a Reference Calculator for converting relevant units of measurement.
Platinum is a Block D, Group 10, Period 6 element. The number of electrons in each of Platinum's shells is 2, 8, 18, 32, 17, 1 and its electronic configuration is [Xe] 4f14 5d9 6s1. In its elemental form platinum's CAS number is 7440-06-4. The platinum atom has a radius of 137.3.pm and it's Van derWaals radius is 172.pm. Platinum is not toxic. Platinum is a member of the platinum group of metals. It is highly corrosion resistant and has numerous catalytic applications. These include in petrochemical cracking catalysts, automotive catalytic converters and in the processes used for proton exchange membrane fuel cells. The metal does not oxidize in air at any temperature. The metal is extensively used in jewelry, electronic wire, and crucibles for corrosive and high temperature laboratory uses and in many advanced instruments. Platinum compounds have application in medicine. Platinum 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. Platinum was first discovered by Julius Scaliger in 1735. The origin of the name comes from the Spanish word platina meaning silver. See Platinum research below.
Selenium is a Block P, Group 16, Period 4 element. The number of electrons in each of Selenium's shells is 2, 8, 18, 6 and its electronic configuration is [Ar] 3d10 4s2 4p4. In its elemental form selenium's CAS number is 7782-49-2. The selenium atom has a radius of 116.pm and it's Van der Waals radius is 190.pm. The EPA does not classify selenium as carcinogenic, although selenium sulfide is a probable carcinogen. Selenates and selenites which are compounds of selenium, are highly toxic. Hydrogen selenide gas (SeH2) is the most acutely toxic compound of selenium. Selenium exhibits both photovoltaic action, where light is converted directly into electricity, and photoconductive action, where the electrical resistance decreases with increased illumination. of photocells and exposure meters for photographic use, as well as solar cells. Below its melting point, selenium is a p-type semiconductor and has many uses in electronic and solid-state applications. Selenium 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. Selenium was first discovered by Jons Berzelius in 1817. The origin of the name Selenium comes from the Greek word "Selênê" meaning moon. See selenium research below.
