Silicon Carbon Alloy Production Method
Carbothermal reduction method. The method is to mix silica and coke according to a certain proportion, and then carry out carbothermal reduction reaction at high temperature to generate silicon and carbon monoxide, and then prepare different content of silicon carbon alloy by controlling the reaction conditions and reaction time. The silicon carbon alloy prepared by this method has lower carbon and silicon content, but its metallurgical properties and serviceable properties are also better.
Mechanical mixing method. Ferrosilicon and silicon carbide were mixed according to a certain proportion, and silicon carbon alloy was prepared by mechanical stirring and grinding. The silicon carbon alloy prepared by this method has relatively uniform composition and good physical properties, but its metallurgical properties and operational properties are relatively poor.
Electric furnace melting method. By melting ferrosilicon, silicon carbide and other alloy materials in electric furnace, different content of silicon carbon alloy can be prepared by controlling the melting temperature and time. The silicon carbon alloy prepared by this method has better metallurgical and serviceable properties, but its cost is high and it has a certain impact on the environment.
In general, the method of preparing silicon carbon alloy needs to be selected according to the specific application scenario and needs. Different preparation methods have certain effects on the composition, physical properties and metallurgical properties of silicon carbon alloy. Therefore, in the preparation of silicon carbon alloy, it is necessary to consider various factors and choose their own preparation methods and process conditions.
