http://www.zzhw66.com/ alumina powder preparation process, also need to use the appropriate filler, since there will be a certain degree of permeability different from each other to produce, so the choice between the filler and the alumina powder should be mutually reinforcing effect. What kind of products are more satisfactory? In the traditional process, in general, is the use of sintering filler, but this does not achieve the desired effect is expected, so now with a fused corundum-type filler. In contrast, the new packing not only highly stable, more easier to get the appropriate particle size and distribution, so as a filler in terms of easy to do. Adding boric acid as long as fused alumina raw material in industry as an additive during a workout, you can obtain the fused alumina-alumina powder filler to reach more than the standard amount to participate. Visible, alumina powder filler great influence on the performance of the performance is also due to filler use of aluminum powder and greatly improved.
