| titleOfInvention | Preparation method for tib 2 or (zr, hf) b 2 ceramic powder |
| abstract | A preparation method for TiB 2 or (Zr, Hf) B 2 ceramic powder, comprising: preparing raw materials according to the mass ratio of reducing agent: titanium source: boron source: molten salt containing alkali metal compound being 1.0: (0.7-1.2): (0.7-4.0): (0.2-20.0); mixing the raw materials uniformly; performing heat treatment in a protective atmosphere under 600-1300°C for 0.5-8 h; dissolving the raw materials with water or alkali solution at room temperature of -250°C; and performing washing and drying to obtain TiB 2 ceramic powder. A reducing agent is one or more of silicon powder and aluminum powder; a titanium source is one or more of Ti powder and TiO 2 powder; a boron source is one or more of boron hafnium, boric acid, sodium tetraborate, potassium tetraborate, and lithium tetraborate; a molten salt containing an alkali metal compound is one or more of sodium hydroxide, sodium silicate, sodium carbonate, potassium hydroxide, potassium silicate, potassium carbonate, lithium hydroxide, lithium silicate, lithium carbonate, and sodium aluminate; and a compound containing (Zr, Hf) is one or more of metal (Zr, Hf) powder and (Zr, Hf) 2 powder. The preparation method has the characteristics of low production cost, environmental friendliness and easy industrial production, and the prepared products have a small particle size and a narrow particle size distribution. |
