microsilica is commonly referred to as the micro powder in the industrial field. the microsilica is made by collecting and processing the smoke and dust from industrial waste gas in the industrial electric furnace at high temperature during the refining of industrial silicon and industrial ferrosilicon. its particles are very, very small, and the average particle size is almost several levels of nanometer, so people call it microsilica.
the price of silica fume is mainly determined by production and demand. for example, the production of microsilica for refractories is low and the price is high.
the high yield of fine microsilica for concrete is cheap. for example, in 2007, when the output of micro-microsilica was very low, the price could be sold to 2,000 yuan per ton. in 2016, the annual output of the same micro-microsilica was delivered at only 1,000 yuan per ton. it also includes a lot of freight and taxes.
of course, the application of micro-microsilica is also very wide, such as cement, concrete, refractories, rubber, chemical dispersant, and so on. but it is popular in the material industry, because of its refractory and wear-resistant properties, can be used to make ceramics, heat insulation materials, wear-resistant materials, and so on. generally in micro microsilica fireproof property of the material it can increase to 100 ℃, its wear resistance can be increased by twenty percent. there is also a large use, is used in mortar and concrete, can be built to the building floor, pier, road and other public facilities, security. used as a reinforcing material for organic compounds. because its composition and gas - phase production of white carbon black similar. can be used in rubber, resin, paint, paint, unsaturated polyester polymer materials used as filler materials.
