Another part of Sahand Industrial Group's activities is the production of chemicals used in making different types of glass. Among these products, we can mention sodium carbonate (light sodium carbonate and heavy sodium carbonate). These chemicals are used in various industries. Sodium carbonate is a solid chemical substance with a crystalline and powdery structure.
Light sodium carbonate has finer grains than heavy sodium carbonate but is quite similar in chemical composition. In most cases, heavy sodium carbonate is used in the glass industry because it has larger particles and is less likely to spread during transportation and collect dust.
