Abstract
Sodium chromate is obtained by heating in a current of hot air in a muffle, a mixture of chromium ore with sodium carbonate with or without lime or calcium carbonate. The materials are formed into briquettes and are arranged in the muffle, for instance in rows with spaces between so as to allow contact with the current of air. Stirring or turning of the charge is unnecessary and undesirable, and the operation is complete in one burning.
