What does chrome flour work in ceramic industry?
Chrome flour is mineral powder,made of chromite sand,through grinding via mill to 200mesh 325mesh 400mesh 500mesh 600mesh 800mesh 1000mesh 1200mesh 1500mesh 2000mesh 2500mesh etc.
- As an additive for ceramic pigments and glazes
Chrome flour contains Cr2O3, which plays a variety of important roles in ceramic glazes. It can be used as an additive for ceramic pigments and glazes to give ceramics bright colors and a beautiful appearance.Specifically, the application of chrome flour in ceramic pigments can bring a variety of colors, including green, yellow, purple and blue, and these different colors of chromium oxide ceramics are suitable for different applications.
- Adjusting the sintering temperature
Chrome flour can also effectively reduce the sintering temperature of alumina ceramics and shorten the sintering time, thereby reducing production costs and improving production efficiency.
Experiments have shown that when a certain amount of chromium oxide is added to alumina, the sintering temperature of the material will be significantly reduced. This effect of reducing the sintering temperature helps to reduce energy consumption, improve production efficiency, and may make ceramic products have better microstructure and performance.
- Improving material properties
Chrome flour can not only enhance the hardness, wear resistance and corrosion resistance of the material, but also improve the flexural strength, fracture toughness, thermal shock stability and thermal conductivity of alumina ceramics.
These performance improvements make industrial ceramics excellent in a wider range of applications, such as aerospace, machinery, automobiles and electronics.
4.Specific application examples
In the production of industrial ceramics, chrome flour is often used as a key raw material for making ceramics with special properties. For example, when manufacturing furnace tubes, furnace linings and other parts of high-temperature furnaces, the use of ceramic materials containing chrome flourr can improve their high temperature resistance and corrosion resistance.
