Hardness of alumina powde

  Alumina micropowder is a white crystalline powder with relatively uniform particle size
What about its hardness? The following introduction: 1
The hardness of alumina powder is hv=2200kg/mm2 The toughness of the alumina powder is not high, but the hardness of the alumina powder is 7
5
When the alumina powder is ground and polished, the abrasive particles are easy to break up
Because the heat generated during grinding is very small, grinding and polishing are suitable for high carbon steel, grinding steel, thin-walled parts and high-speed steel
2
In the alumina micro powder, it has high stability and low sodium content
At the same time, the crystal size of the alumina micro powder is very small
When grinding for a long time, the particle size will be close to the size of the original crystal
The alumina micro powder can also have high compatibility with other components, with particle size division
3
In terms of the characteristics of alumina micropowder and formed alumina, it is a high-performance refractory designed and produced, and it is a ground product
There are a large number of micropowders in it, and it also has the friendly ignitability
In the formed alumina, there is a ceramic combination of reinforced matrix, which improves the corrosion resistance, mechanical strength and wear resistance, and optimizes the particle size distribution, Thus, the amorphous refractory material and water addition can be reduced, so its fluidity can be improved
Because of the hardness of alumina powder, it is widely used in heat conduction, polishing, electroplating, catalyst, etc
