White corundum is widely used in chemical industry, mainly in the following aspects:

I. Catalyst carrier

White corundum is often used as catalyst carrier because of its high specific surface area and good chemical stability. It can be used in catalytic reactions in petrochemical, environmental protection and energy fields, and can improve the efficiency and selectivity of chemical reactions.

II. Corrosion-resistant equipment and pipeline lining

White corundum has excellent chemical corrosion resistance and can resist the corrosion of corrosive media such as acid, alkali and salt. Therefore, it is widely used to manufacture liners and pipes of chemical equipment to ensure the long-term stable operation of equipment in harsh chemical environment.

III. Coatings and coating additives

Because of its high hardness and corrosion resistance, white corundum micropowder is often added to paints and coatings to improve the wear resistance and corrosion resistance of materials. For example, it can be used to make wear-resistant coatings, anti-corrosion coatings and high-temperature protective coatings, and is suitable for chemical equipment, ships, industrial floors and so on.

IV. Refractory materials

White corundum refractories are used to manufacture furnace linings, furnace tops and other components in high-temperature reactors and incinerators in the chemical industry. Its high melting point (about 2050°C) and good thermal stability make it stable at high temperature.

V. Water and waste gas treatment

White corundum can also be used as a filter medium in water treatment and waste gas treatment, which can effectively remove suspended solids and harmful substances in water, and at the same time serve as a catalyst carrier or filter material in waste gas treatment.

VI. Other applications

White corundum can also be used to manufacture components, reaction vessels and pipelines of chemical pumps, and improve the wear resistance and service life of equipment.

White corundum plays an important role in chemical industry because of its high hardness, high purity, high temperature resistance and corrosion resistance, which provides efficient and stable material support for chemical production.
