11. Uranium is pyrophoric when finely divided. 12. Magnesium powder and shavings are pyrophoric ( they oxidise rapidly when exposed to the air ). 13. Thickened pyrophoric agent, a pyrophoric replacement of napalm, is a triethylaluminium thickened with polyisobutylene. 14. Thickened pyrophoric agent, a pyrophoric replacement of napalm, is a triethylaluminium thickened with polyisobutylene. 15. Due to their pyrophoric nature, organozinc compounds are generally prepared using air-free techniques. 16. This colorless pyrophoric liquid is mainly used to make linear primary alcohols and ?-olefins. 17. For special applications, pyrophoric igniters can be used which burst into flame in contact with air. 18. Although the distilled rubidium was pyrophoric , they were able to determine the density and the melting point. 19. At the time, it was produced in the form of a powder, and was highly pyrophoric . 20. A subcomponent self-assembly tetrahedral capsule developed by Jonathan Nitschke renders pyrophoric white phosphorus air-stable.
