Phosphorus, violet 99.99% — Luciteria

    Phosphorus comes in a couple more forms, or allotropes, besides the red powder. White phosphorus is infamous for its toxicity and flammability and has been literally used as a weapon in many wars. It too, unsurprisingly, is strictly regulated. That leaves violet and black.

    Phosphorus - Sciencemadness Wiki

    Violet phosphorus - also known as monoclinic phosphorus, it is solid brown-violet. It is formed by heating red phosphorus in a sealed tube at 530 °C or white phosphorus at 500 °C in molten lead for 18 hours. Insoluble in all solvents, violet phosphorus has low reactivity and ignites in air at 300 °C.
