aluminate cement

Performance features 1.high melting point, 2.high hardness 3.stable crystal form 4.high mechanical strength

1. Excellent adaptability and compatibility make the products very suitable for amorphous refractories with high  technology content, such as low cement castables (LCC) and ultra-low cement castables (ULCC). At the  same time, the products are also extensively suitable for various construction methods.
