Complex physicochemical reactions occur during the smelting process. When the temperature reaches 1750&deg;C, quartz sand undergoes carbothermal reduction to produce SiO. At temperatures exceeding 2160&deg;C, Si undergoes gasification and sublimation, reacting with oxygen in the air when descending to temperatures below 1100&deg;C, forming SiO. SiO and Si in the high-temperature gas quickly oxidize in the ascending air, condense and cool at lower temperatures, forming micro-nano particles. These particles are collected through filtration in dust collectors, resulting in microsilica.<\/span><\/p>\n<h3><span style=\"color: #181818; font-size: 12pt;\"><strong>1.2 Microsilica Capture<\/strong><\/span><\/h3>\n<p style=\"line-height: 1.75;\"><span style=\"color: #181818;\">Industries involved in the production of industrial silicon and ferrosilicon are high-energy-consuming and heavily polluting.
