Alumina Plate,Alumina Ceramic Plate,Al2O3
Alumina plates are made of aluminum oxide. We use high-quality alumina as raw material to make advanced ceramics, and grind the alumina powder to the sub-micron (nanometer) level, so that there are basically no voids in the material, and its density is about 3.9g/중3 . Alumina ceramics have superior properties. Ceramic plates have high temperature resistance, high hardness, and strong wear resistance, and can be used in industrial machinery scenarios. At the same time, its electrical insulation and corrosion resistance are also excellent, and it also has many uses in the chemical industry.
