What is the difference between white fused alumina and alumina?
It’s just that many people are not technical, but laymen. They don’t know much. They vaguely know that the alumina content of white fused alumina is more than 99%, close to 100%. Then they can’t understand the relationship between them. They even think they are the same substance, but they have different names. Are white corundm and alumina the same substance? If not, what are the differences between the two?
1. white fused alumina is an artificial abrasive made from alumina as raw material, melted at high temperature and cooled. Alumina is a high hardness compound.
2. The main component of white fused alumina is alumina. Specifically, it is a crystal shape of alumina, that is, α-Al2O3. In addition to alumina, there are small amounts of impurities such as iron oxide and silicon oxide. Alumina is a stable oxide of aluminum. The main elements are oxygen and aluminum, chemical alumina. There are many uniform and non-uniform crystals, such as α-Al2O3, β-Al2O3 and γ-Al2O3.
3. Physical properties white fused alumium oxide has a melting point of 2250℃ and its appearance is a triangular crystal. The melting point of alumina is lower than 2010℃-2050℃. Its appearance is a white powder with a γ phase.
4. white a al2o3 is generally used in the manufacture of abrasives, catalysts, insulators, casting, sandblasting and other industries. Alumina is mainly used in heat conduction, polishing, electroplating, catalysts and other industries. After several comparisons, we should know the differences between white fused alumina and alumina, and do not confuse them when using them!
