The difference between white and brown corundum

Said so much about the knowledge of brown corundum and white corundum, as if they forgot to introduce the difference between the two, in order for everyone to distinguish, it is still necessary to give you a description of the main difference between white corundum and brown corundum, so that there will be a certain basis for selection.
Under normal circumstances, it can be distinguished from the color, but sometimes because of the influence of certain factors, the color is not easy to distinguish. At this time, we have to look at the performance, white corundum is a kind of corundum products made of high-quality aluminum oxide powder as raw materials, so it is relatively stable in terms of high purity, self-sharpness, acid and alkali corrosion resistance, high temperature resistance and hot state.
Brown corundum is a kind of corundum products made of bauxite, anthracite and iron dust as the main raw materials, so there are some small differences in hardness compared with white corundum. In addition, the processing technology and application of white corundum and brown corundum are also slightly different. In the future, when we choose corundum products for different purposes, we can use the above knowledge points as a reference to make the right choice.
