Silicon Carbide 88% Grain For Refractory
Product Description
Our 88% silicon carbide refractory aggregate is specially designed for high-temperature refractory applications, targeting the common pain points of short lining life, easy cracking and high material cost in industrial furnaces. With strict composition control and uniform particle distribution, this black SiC grain for refractory castables acts as high-performance aggregate and filler in various refractory products. It delivers outstanding high-temperature stability, slag resistance and thermal shock resistance, making it the ideal choice for refractory manufacturers and furnace engineering projects.
This cost-effective SiC grain for refractory materials not only meets the performance requirements of most high-temperature working conditions but also reduces your overall production cost. Whether you need aggregate for refractory precast blocks or particles for gunning mixes, our low impurity SiC grit for refractory gunning mixes can be customized to match your formulation perfectly.
