CALCINED SODA (soda ash). The production of C.s. by the Solve method (chemical interaction of carbon dioxide and ammonia with a saturated water solution of chloride and the subsequent burning of the resultant sodium bicarbonate) was mastered in Bashkortostan at the Sterlitamak Soda Plant in 1951. C.s. is produced of grades A (granular) and B (powdered).
