MAIN APPLICATIONS
Chromite powder in manufacturing stainless steel and alloy steel
The abrasive resistance and corrosion resistance of stainless steel and alloy steel can be improved through adding certain chromite powder
Chromite Powder in refractory industry
Chromite powder usually is used for making high chrominum refactory bricks which are used in internal coating of high temperature furnace and stove.
Chromite Powder in pigment and coating
Chromite powder is a main mineral pigment,to produce green pigment and chrome yellow pigment.besides,chromite powder can be added in coating to increase the color and weather ability of coating.
Chromite Powder in plastic and rubber
To increase plastic and rubber’s intensity,hardness and abrasive resistance,chromite powder will be added in plastic and rubber.
Chromite powder in electronic material
Chromite powder can be used in electronic material such semiconductor materials and magnetic material,adding maderate chromite powder can enhance electrical conductivity,magnetism and high-temperature resistance.
