Lead Sulfide Powder Description

Lead sulfide is a dark blue-gray nearly black cubic crystal. It can be prepared by hydrogen sulfide being passed into an acidic solution of lead nitrate or by heating lead carbonate with sulfur. Lead sulfide is insoluble in acids, insoluble in water, and insoluble in bases. High purity lead sulfide can be used as a semiconductor. Stanford Advanced Materials (SAM) has over two decades of experience in the sale and manufacture of lead sulfide powder.
