the microsilica collected by the ferroalloy factory is generally purified and encrypted, and eventually becomes commodity microsilica, which is also known as silica dust, microsilica and microsilica in engineering. its main component is sio2, followed by a small amount of al2o3, cao, k2o, fe2o3, mgo and other substances.

at present, china has thousands of silicon iron and industrial silicon furnaces, with an annual output of about 250,000 tons of microsilica, but now the environmental protection equipment can only collect 50,000 tons, and the current market price of microsilica is 3,000 yuan/ton. therefore, while directly polluting the environment, 600 million yuan is drained through the chimney each year. therefore, the collection of microsilica as a non-renewable resource is not only an environmental benefit, but also a market with broad economic value.

in the process of smelting ferrosilicon and industrial silicon (silicon metal), a large amount of highly volatile sio2 and si gases are produced in the mineral thermal electric furnace, which are formed by rapid oxidation, condensation and precipitation with air. it is the product of large-scale industrial smelting, and the whole process needs to be recycled with dusting environmental protection equipment, because the quality is relatively light, and also needs to be encrypted with encryption equipment.

half encryption microsilica is mainly composed of glassy state sio2, particle characteristics of ultrafine powder, particle size less than 1 um, the vast majority of the average particle size in 0.1 um, has the very high specific surface area (300-400 ㎡ / kg) and the activity of ash.

product name: li xinyuan microsilica  (semi-encrypted silica dust) type: sf90 semi-encrypted specification: 25kg bag

this specification product density is 320-400kg/m3, silica >90%, good fluidity, more suitable for refractories.
