Do you know the origin of the name of silicon micro powder?

Before introducing the source of the name of silicon micropowder, you must first know what is silicon micropowder, which is made of natural quartz (SiO2) or fused silica (natural quartz is amorphous SiO2 after high temperature melting and cooling) through crushing, ball milling (or vibration, airflow milling), flotation, acid cleaning purification, high-purity water treatment and other processes. Silicon micro powder is pure white in color, with particles in angular or spherical shapes, extremely fine, and the finest particle is about 0.5 μ m. It is a non-toxic, odorless, and pollution-free inorganic non-metallic material. Due to its excellent properties such as good temperature resistance, acid and alkali corrosion resistance, poor thermal conductivity, high insulation, low expansion, stable chemical properties, and high hardness, it is widely used in chemical, electronic, integrated circuit (IC), electrical, plastic, coating, advanced paint, rubber, national defense and other fields. With the rapid development of high-tech fields, silicon micro powder will also enter a new historical development period.

After understanding the definition of silicon micro powder, let's now introduce the dog blood historical origin of the name silicon micro powder. In the early days, silica micro powder was defined as the fine powder after dust collection in steel plant chimneys (in fact, this is now known as silica fume, also known as micro silica powder, which is different from silica micro powder). In the early 1990s, the refractory materials industry in China mostly used Norwegian silica micro powder (actually the dust collection powder for steel enterprise chimneys), with a fineness of sub micron level. At that time, the use of this product had not yet been discovered in China. Later, when domestic steel companies discovered this problem, the prices of foreign products continued to decline, and at that time they were all called silicon micro powder. In the late 1990s, with the development of China's reform and opening-up and private economy, domestic electronic circuit boards also developed rapidly. Lianyungang Donghai, Guangdong Dongguan, Foshan and other places saw business opportunities and carried out ultrafine purification of quartz powder. Such products have no name, they are called quartz powder and ultrafine quartz powder, which seem too lacking in level and technological content. Therefore, they are simply called silicon micro powder. With the increasing number of enterprises, this term has gradually formed a trend and now occupies the high ground of the term, taking away the initial definition and connotation of silicon micro powder. The original silicon micro powder (actually known as silica fume now) had to adopt a nickname called microsilica powder due to insufficient market power. In short, silicon micro powder was a product plundered from ultrafine quartz powder in the century. This plot is really melodramatic, but it is indeed very intriguing. Through the above introduction, I believe readers have gained a deeper understanding of this common powder in silica micro powder.
