Potassium phosphide is an inorganic semiconductor compound with the formula K3P. It appears as a white crystalline solid or powder. [2] It reacts violently with water and is toxic via ingestion, inhalation and skin absorption. [3] It has a hexagonal structure. [1]
Potassium phosphide can be synthesised by simply reacting the two elements together: [4]
Potassium phosphide is used in high power, high frequency applications and also in laser diodes. [2]
