HOW DOES CHROMITE FLOUR WORK IN CERAMIC GLAZES?
Chromite flour is also called chromite powder,chrome flour or chrome powder etc.
It mainly works in glass and ceramic fields.
Today we talk aout how chromite flour works in ceramic glazes.
First,It produce brigt color. Chromite flour contains rich chrominum,which can make ceramic get bright colors such as green,yellow,purple and blue etc.
Secondly, improve the ornamental : Chromite flour can significantly improve the gloss of ceramic products, giving ceramic products a better visual effect. At the same time, it can maintain a stable color at high temperatures, making ceramic products less likely to fade during the firing process, increasing the ornamental and artistic value of ceramic products
Thirdly, improve material properties : The addition of chromite flour can significantly enhance the hardness, wear resistance and corrosion resistance of ceramic materials. It can also improve the flexural strength, fracture toughness, thermal shock stability and thermal conductivity of alumina ceramics.
The last,adjust the sintering temperature : Chromite flour can effectively reduce the sintering temperature of alumina ceramics and shorten the sintering time, thereby reducing production costs and improving production efficiency.
From above ,we can know that chromite flour is very important in making ceramic glazes,then what is the chromite flour?
