Ultra-low cement castables, as the name implies, are refractory castables with low cement addition. The water addition in the general laboratory is 2.5%, and the water addition in on-site construction does not exceed 4%.
Magnesite is an important mineral resource with unique characteristics and a wide range of uses.
Brown corundum is a gem formed by the crystallization of aluminum oxide (A1203). Because corundum has excellent high-temperature properties and mechanical strength, it is widely used in many industrial fields such as metallurgy, machinery, chemical industry, electronics, aviation and national defense.
Because of its remarkable hardness and chemical durability, corundum—a crystalline form of aluminum oxide (AlO₃)—is a valuable material in industrial applications, especially as an abrasive.
Corundum, a mineral known for its exceptional hardness and vibrant color variations, can occur naturally or be manufactured synthetically.
Corundum is a fascinating mineral that plays a critical role in various industries, from jewelry to industrial manufacturing.
