Alumina powder casting coating can affect the internal and surface quality of castings.
The refractoriness depends on its chemical composition. The Al2O3 content, sintering temperature, TiO2, FeO3 and other impurities in bauxite have a great impact on the coating.
In addition, the particle size and particle size distribution of bauxite are also important factors affecting the density and permeability of the coating, especially the EPC coating. Its permeability is a major feature different from other sand casting coatings.
