In the field of refractory materials, corundum, as an important raw material, has become a widely used material in the refractory industry due to its excellent physical and chemical properties. This article will introduce the basic characteristics, wide applications, market status, and production process of corundum in detail, and focus on the 200-mesh corundum high-efficiency grinding machine to reveal to you how it leads a new era of efficient grinding.

Corundum is a gem formed by the crystallization of aluminum oxide. Its hardness is second only to diamond and cubic boron nitride, and its Mohs hardness reaches 9. The name of corundum originated from India. Its main component is Al₂O₃, and there are three variants: α-Al₂O₃、β-Al₂O₃、γ-Al₂O₃. Due to its excellent physical properties, corundum is widely used in advanced grinding materials, watches, bearing materials for precision machinery, and other fields.

Application of corundum

The application range of corundum is extremely wide, covering many industrial fields such as metallurgy, machinery, chemical industry, electronics, aviation, and national defense. Due to its high temperature resistance, corrosion resistance, and high strength, corundum is used as a crucible and vessel for casting steel sliding doors, smelting rare precious metals, and special alloys; in chemical systems, corundum is used as various reaction vessels and pipelines and chemical pump parts; in the mechanical field, corundum is used to make knives, molds, bulletproof materials, etc. In addition, transparent corundum products can also be used to make lamps and microwave fairings, and Na-b-Al₂O₃ products are electrolyte materials for making sodium-sulfur batteries.

Corundum Market Situation

In recent years, with the advancement of science and technology and the rapid development of industry, the demand for corundum has continued to grow, and the market prospects are broad. China, India, and Brazil are the world’s major corundum producers, among which China is the world’s largest producer and exporter of white corundum. The corundum market presents a state of basic balance between supply and demand, with product quality continuously improving and application areas continuously expanding. Especially in high-end fields such as high-precision grinding and polishing, the application of corundum is becoming more and more extensive.

The production process of corundum

The production process of corundum includes multiple steps such as material preparation, smelting, cooling, crystallization and processing. First, the high-purity aluminum oxide powder is screened and dried to ensure the uniformity and purity of the raw materials. Then, the aluminum oxide powder is placed in an electric furnace and heated to a high temperature to melt it into a liquid state. In the molten state, the aluminum oxide molecules rearrange themselves to form a crystal structure and form corundum particles. Then, the temperature is slowly lowered so that the corundum particles gradually solidify into a solid. Finally, it is heated again to make the crystal structure more stable and improve the hardness and wear resistance of the corundum.
