Synthesis method: The production of chromium diboride powder usually adopts the reaction sintering method. The main principle of this method is to mix chromium powder and boron powder in a certain proportion, and then perform high-temperature solid-state reaction to generate chromium diboride powder. Usually, the reaction temperature of this method is 1600-1900 ℃, and the reaction time is 1-3 hours. The reaction products can be separated by stages to obtain chromium diboride powder with uniform particle size distribution, high melting point, and uniform composition.
Purpose:
1. High performance grinding tool materials
Chromium boride powder has very high hardness and wear resistance, and can be used in the production of abrasives, polishing materials, grinding tools, etc. For example, high-performance ceramic blades can be prepared using chromium diboride powder, which can be used to process high hardness, high-strength materials such as tungsten steel and ceramic materials.
2. Electronic materials
Chromium diboride powder does not have excellent conductivity and thermal conductivity, and can be used for the production of electronic materials. For example, chromium diboride powder can be prepared into thermistor materials, electrical contact materials, etc.
3. Coating materials
Due to the relatively high melting point of chromium diboride powder, it can be used to prepare high-temperature and corrosion-resistant coating materials. For example, chromium diboride powder can be mixed with materials such as ceramics to prepare highly corrosion-resistant and wear-resistant coating materials, which can be used for pipelines, containers, etc.
4. Metal based composite materials
Chromium diboride powder can be used to prepare metal based composite materials. For example, by mixing it with metal powder, ceramic materials, etc. and heating and sintering, excellent performance and high strength metal based composite materials can be obtained.
