White aluminum oxide powder is a very important industrial raw material,acts significant roles in many fields.its charactoristics such as high hardness,high purity and good chemical stability makes it used widely in manufacturing,abrasives, coating etc.
一、Physical properties of white aluminum oxide powder
1. High hardness
White aluminum oxide powder own extreme high hardness(mohs 9.0),which is only lower than diamond.so it is widely used in abrasives,abrasive tools and cutting tools and so on.its high hardness makes white aluminum oxide work well in processing hard material.
2. HIgh purity
White aluminum oxide powder has high purity,without impurity,which makes it has special advantage on producing high precision product,because it can improve quality and function of product effectively.
3. Good chemical stability
White aluminum oxide powder possesses good chemical stability,which can guarantee its physical properties not change under any environment,then the product made from white aluminum oxide own long lifetime and stable performance.
4. Grit shape and particle size distribution(PSD)
The shape and PSD of white aluminum oxide has important influence on its application performance,resonable shape and PSD can increase its processing efficiency and product quality.
二、Applied range of white aluminum oxide powder
1. Abrasives and abrasive tools field
Because white aluminum oxide has high hardness and good chemical stability,it is widely used in abrasives and abrasive tools field.It can used in manufacturing abrasive toils such as grinding wheels,millstone and polished wafer;also can used in grinding and lapping all kinds of mental and nonmetal.
2. Manufacturing field
High purity and good stabilty of white aluminum oxide powder makes it work well in manufacturing.It can be raw mateiral of producing ceramic,glass and electron component.Meanwhile,whie aluminum oxide powder also can be used in produceing certail special material such as high temperature material ,wear-resistant material and so on.
3. Coating
White aluminum oxide powder can be part of coating,using to produce high hardness,wear-resistant and high antiseptic coating.White aluminum oxide powder is able to imcrease hardness and wear-resistance of coating to extend its service life.At the same time,white aluminum oxide powder also can enhance adhesive force and weather fastness of coating,then makes it owning better function.
