The role of alumina powder in refractory castables

The role of alumina powder in refractory castables 1. To enhance the quality of refractory castables, it is crucial to minimize the calcium aluminate cement content while maintaining satisfactory strength and high-temperature mechanical properties. The key lies in optimizing particle packing density. 2. Incorporating alumina micro powder, submicron powder, or even nano-alumina powder into refractory castables effectively reduces the CaO content, minimizing the formation of low melting phases at high temperatures and improving the castables’ high-temperature mechanical properties. It also enhances the medium temperature strength, reduces water usage, and increases the castables’ density. 3. Alumina micro powder plays a vital role among different types of castables. Its particle size, distribution, and specific surface area significantly impact the performance of refractory castables. Adding alumina micro powder to fill the gaps between aggregates greatly influences the castables’ performance by increasing bulk density. 4. Numerous refractory castable manufacturers have devoted extensive efforts to micro-powder technology. Utilizing composite micro-powders with diverse particle size distributions remarkably enhances packing density and reduces water consumption, benefiting mechanical properties like high-temperature flexural resistance and post-thermal shock strength. Smaller micro powder particles tend to increase fluidity and setting time of refractory castables. You are welcome to leave your comments...
