What are the Functions of Micro-Powder in Refractory
Sep 17 2020 · Silica powder is an essential raw material in refractory castables. Adding silica powder to the castable will increase the flow value of the castable. The silica powder has a small particle size and is a spherical particle which is extremely easy to enter the tiny voids of the castable. Performance Comparison of Refractory Concrete and Refractory Bricks The refractoriness is similar to that of refractory bricks of the same material. However because the refractory concrete ( castable ) is not sintered it shrinks greatly during the initial heating so the load softening point is slightly lower than that of refractory bricks.
