Product Details

Potassium Hexafluoroaluminate#13775-52-5

Potassium hexafluoroaluminate is a white or light gray powder, or a blocky crystal. About 950℃. It will melt into liquid at high temperatures and has a certain degree of fluidity. Slightly soluble in water, its solubility in water increases slightly with the rise in temperature. Insoluble in ethanol. It is stable under normal temperature and pressure and will not decompose easily. However, when exposed to strong acids, a reaction occurs, releasing hydrogen fluoride gas.
