White loose powder or crystals. The relative density was 1. 178. Melting point 585 ° C, about 500 ° C in vacuum began to decompose, stable in air, not hygroscopic. Potassium borohydride is readily soluble in water, and hydrogen is completely released when the aqueous solution is heated to 1000 °c. Soluble in liquid ammonia, slightly soluble in methanol and ethanol, almost insoluble in ether, benzene, Tetrahydrofuran, methyl ether and other hydrocarbons. Stable in alkaline environment, when inorganic acid decomposition and release of hydrogen.
