950microsilica: the appearance is grey powder and white silicon powder. the sio2 content is 94-95% and is semi-encrypted. it can be applied to high-grade refractory materials, baffle, silicon carbide cover, etc., as necessary admixture.
950 microsilica powder is widely used in refractory industry. practical application in the following aspects:
1. production of amorphous and shaped refractory products as additives; make its strength, high temperature performance is greatly improved
2, for the whole of ladle pouring in combination with coagulant
3, and other refractory products of cohesive agent, binder, coagulant, additives industry of silicon powder call is confusion.
in fact there are three different types of products:
the micro microsilica: in smelting silicon metal, ferrosilicon, dust by dust environmental protection equipment recycling. this product main composition is sio2, the industry much call for active microsilica, micro silicon powder.
2. the microsilica: with natural white quartz, melting quartz as raw material, after the primaries, crushing, grinding, purification and dehydration, classification of refined quartz silica powder.
3. silicon metal powder: silicon metal piece after crushing grinding of silicon metal powder, this product should not actually call micro silicon powder, should call for silicon metal powder. when the user chooses should be treated differently.
