Chromite sand is a natural mineral sand with chromite as its main component, possessing high melting point, high hardness, and excellent corrosion resistance.
Its main component is Cr₂O₃ (chromium trioxide), typically ranging from 30% to 60%. Chromite sand is widely used in casting, refractory materials, and chemical industries.
In the casting industry, chromite sand is often used as molding sand and core sand due to its good thermal stability and resistance to metal penetration.
In the refractory materials field, it can be used to produce high-temperature refractory products such as chrome bricks and chrome-magnesium bricks.
In the chemical industry, it is an important raw material for the preparation of chromium salts. The particle size distribution, chemical composition, and physical properties of chromite sand directly affect its application performance. When purchasing, attention should be paid to the Cr₂O₃ content, impurity components (such as SiO₂, Fe₂O₃, etc.), and particle size index according to the specific application. It is recommended to dry it before use (temperature controlled at 200-300℃), and to protect it from moisture during storage.
We currently have these products in stock. Our chromium ore powder boasts advantages such as a high Cr2O3 content of 46.36% and extremely low impurity content, making it suitable for various fields including metallurgy, electronics, and chemicals. Please contact us for the best solutions.
