Silica fume was discovered as a by-product of the silicon metal production process. Imidlertid, it has proved high-value thanks to its physical and chemical properties.
Ildfaste materialer, der kan bruges i højtemperaturmiljøer, er samlet kendt som ildfaste materialer, ildfaste materialer er meget udbredt i metallurgi, kemisk industri, maskinfremstilling
In concrete and refractory materials, often use silica fume as admixture, so as to improve the performance of materials, usually in concrete mainly to improve
Refractory microsilica powder is amorphous structure, with good volcanic ash surface activity. With the increase of carbon and iron oxide content, the appearance color of
It is observed that only the best high-temperature resistant materials are used as refractory materials. The refractory materials are made from a mixture of silicon,
