Low ash medium-grained graphite of GMZ, GMZ-O, GMZA, 3OPG type

It is used in manufacturing pipes, screens, bases for screens, crucibles, heaters working in neutral environments up to 2300°С and oxidizing environment up to 400-450°С; in vacuum and other closed electric furnaces. Besides it is used for tiles and blocks for lining of chemical apparatuses, cast iron and slag chutes and so on.

Materials of the given group possess high durability in aggressive environments whilst exposed to various types of temperature and mechanical stress.
