| titleOfInvention | A kind of preparation method of silicon carbide powder |
| abstract | The invention provides a method for preparing silicon carbide powder. The pulverized fly ash or ferronickel slag is soaked in an acidic solution and then combined with carbon black to generate silicon carbide at high temperature. After crushing, grading, shaping, Purify, then use ethyl orthosilicate as the silicon source, water-soluble starch as the carbon source, and under the action of crystallization aids, a uniform silicon carbide thin layer is formed on the surface of silicon carbide powder in situ by microwave high-temperature heat treatment , to reduce the shape irregularity of fine-grained silicon carbide powder and improve fluidity; the invention makes full use of solid waste and uses fly ash and/or ferronickel slag as raw materials, which can reduce production costs and waste of resources. |
