Acheson process for silicon carbide production
Silicon carbide production raw materials: Quartz sand (SiO₂) and petroleum coke (C) are mixed in proportion. High temperature reaction: Heating to 2000-2500℃ in a resistance furnace, the reaction occurs: SiO₂ + 3C → SiC + 2CO↑. Cooling and sorting: Slow cooling after reaction, crushing, pickling to remove impurities, and grading by particle size.
Advantages: Mature process, simple equipment, low investment. Suitable for large-scale production, easy to obtain raw materials. Disadvantages: High energy consumption (long-term high temperature maintenance). Low product purity (containing impurities such as Fe and Al). Uneven crystal size and low production efficiency (intermittent production). Environmental issues (CO emissions, dust pollution). Application: Low-end fields such as traditional abrasives and refractory materials.
