Silica fume was discovered as a by-product of the silicon metal production process. No entanto, it has proved high-value thanks to its physical and chemical properties.
Refractory materials can be used in high-temperature environments are collectively known as refractory materials, refractory materials are widely used in metallurgy, chemical industry, machinery manufacturing
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,
