GW-1 Alpha-Al2O3 Micro Powder

  • Possesses high reactivity and excellent filling properties, resulting in lower water demand and improved fluidity in castables.
  • Used in the preparation of low cement or ultra-low cement castables.
  • Suitable for formulating refractories with higher temperatures, such as corundum-based, corundum-spinel, or spinel-based castables.
  • Applied in the production of electric furnace roof covers, iron trough channels, narrow bricks, and more.


GLW-1 High Alumina Micro Powder

  • When combined with silica micro powder, GLW-1 High Alumina Micro Powder can be used to prepare cost-effective, high-performance low cement castables. It can also be a suitable substitute for some alumina micro powder, depending on the material selection.
  • Used in the preparation of low cement or ultra-low cement castables.


High Alumina Fine Powder

  • High Alumina Fine Powder is uniformly sintered with a dense structure and stable composition. It is an essential component for formulating general low cement refractory castables and rich cement castables.
  • The castables prepared with this powder are primarily used in tunnel kilns, shuttle kilns, reheating furnaces, boilers, industrial kiln linings, and more.
