Description
The main components of silicon carbide low-cement castable include high-purity silicon carbide (SiC) as the aggregate, along with pure calcium aluminate cement and micro-powder as the binder. This material offers excellent strength and wear resistance, making it suitable for environments with high temperatures, high pressure, and corrosive conditions.
