Vanadium Phosphide is a semiconductor used in high power, high frequency applications and in laser and other photo diodes. technical, research and safety (MSDS) information is available as is a Reference Calculator for converting relevant units of measurement.

Tungsten is a Block D, Group 6, Period 6 element. The electronic configuration is [Xe] 4f14 5d4 6s2. In its elemental form tungsten's CAS number is 7440-33-7. The tungsten atom has a radius of 137.pm and it's Van der Waals radius is 200.pm. Tungsten has the highest melting point of all the metallic elements and because of this has its first significant commercial application as the filament in incandescent light bulbs and fluorescent light bulbs. Tungsten 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. Later it was used in the first television tubes.

Phosphorus is a Block P, Group 15, Period 3 element. The electronic configuration is [Ne] 3s2 3p3. In its elemental form Phosphorus's CAS number is 7723-14-0. The Phosphorus atom has a radius of 110.5.pm and it's Van der Waals radius is 180.pm.
