Solubility: soluble in cold water, ethanol, slightly soluble in ether, white and glossy crystal. It tastes bitter. The density is 1.405. The melting point is 180~182 degrees centigrade. It is more hot to decompose. The heating is soluble in water, soluble in ethanol, soluble in ether. When melted, isomerization takes place in part and forms thiocyanate ammonium. The effect of hydrogen sulfide and lime into calcium hydrosulfide, and calcium cyanamide (base) and function.


Use:
It is also used as raw material for making medicine, dyestuff, resin, pressed powder and so on. It is also used as vulcanizing accelerator for rubber and flotation agent for metal minerals.
