We are a refractory material manufacturer, with four major factories: heavy brick factory, light brick factory, monolithic refractory factory and fused-cast brick factory.
We promise to provide you with high-quality refractory materials.
Product introduction of Alumina powder
Alumina powder is alumina solid powder, usually α-Al2O3 Alumina powder, β-Al2O3 alumina powder and γ-al2o alumina powder are processed.
α-Alumina Micropowder/Activated Alumina Micropowder
α- Alumina micropowder is a kind of activated alumina powder produced by using advanced grinding technology and technology after low temperature and normal pressure of high-quality industrial alumina and aluminum hydroxide additive technology. It is characterized by large activity and small particle size. It is especially suitable for shaped products and refractory main materials, plastics, repair materials, spraying materials, coatings and other shaped refractory materials, and has a strong role in improving the high temperature strength and corrosion resistance of refractory materials.
