Utilization of Resource, Russia Using Scrap Made ceramic Glazed Pigment(2009/11/25)

Russia has long time pay attention to the production of waste in ceramics utilization of resources. In recent years in the field of ceramics has invented two patents: one is the manufacture of ceramic pigments with red mud, and the other one is to use waste glass glaze system.

With the red clay pigments and ingredients are from 20-30% chromium, 5 - 10% zinc oxide, 25 -36% red mud (with aluminum bauxite refining waste discharged), and 35-45% of the dolomite formed. .It uses ingredient to produce brown ceramic pigment by low firing temperature. The system with the waste glass glaze ingredients are finely ground glass from the 60-85%, Kaolin 2-4%, sodium carbonate 0.1-0.2%, the rest being composed of obsidian. This glaze formation with more lustrous glaze, such as using green waste glass, can form a gray vitreous glaze, and glaze of the crack resistance is high.
