One article takes you to understand what silica fume is
Silica fume is also known as microsilica , and many industry insiders also refer to it as silicon powder, which has caused a big misunderstanding with another product, "metal silicon powder". Silica fume has two English names, and I personally think SILICA FUME is more accurate. Silica fume, as the name suggests, is the fine particles that float out after high-temperature processing. Silica fume is the smoke and dust emitted from the process of smelting industrial silicon and ferrosilicon alloys, which is melted at a high temperature of nearly 2000 degrees and evaporated through the flue.
The smelting of ferroalloys originated in the West. In order to address the environmental hazards of harmful smoke and dust emitted during the production process, companies began to collect a large amount of this waste and try to find uses to turn waste into treasure. After extensive experimentation and long-term research, various applications have gradually been developed.
It was not until around the 1990s that the application of silica fume entered China. A famous multinational company invested in the construction of the first set of encryption test equipment in northwest China, and since then silica fume has gradually entered the vision of countrymen people.
Nowadays, the use of silica fume (microsilica powder) is very extensive, with many unexpected applications. Of course, the products of silica fume are also very layered, with significant differences in quality. We hope that this product can continue to develop healthily.
