Ceramic powder manufacture. View of the glycine nitrate process for the manufacture of ceramic powder. First a solution is formed of glycine, an amino acid, and metal nitrates. This is heated until it ignites, converting the metal ions into an ash formed of microscopic ceramic particles of the desired oxide composition. The ceramic powder is very pure and chemically homogeneous. It can be consolidated and sintered (heated without melting) to form uniformly dense ceramics for such things as solid oxide fuel cells. This process was developed at the U.S. Department of Energy's Pacific Northwest Laboratory.
