White corundum abrasive is obtained through sintering, and certain requirements are also put forward for sintering to meet the production needs of different products. For example, if the user needs white corundum fine crystal abrasive, under which circumstances is sintering better?

Another reason is that the particle size of white corundum fine grain abrasive is very fine. Once subjected to high temperature, its ability to decompose and oxidize will be enhanced. Therefore, it is best to use low-temperature binders during sintering. As long as the above points are ensured, white corundum fine crystal abrasive that meets the requirements can be sintered.

Through experiments, it has been found that white corundum fine-grained abrasives are generally sintered at low temperatures, because if sintered at high temperatures, the resulting effect will damage the original microcrystalline structure and properties, causing grain growth and potentially forming fine-grained abrasives. So when sintering white corundum fine grain abrasive, it is best to control the firing temperature below one thousand degrees.
