High-Performance Basalt Ceramic Plates for Industrial Wear Protection.

Product Name

Cast Basalt Plates

Overview

Cast basalt plates are special wear-resistant and corrosion-resistant ceramic materials made by melting natural rocks (such as basalt or diabase) or industrial slag at high temperatures, followed by casting and controlled crystallization and annealing. These plates are widely used in industrial wear protection due to their exceptional hardness, long service life, and strong chemical resistance.
