White corundum, Brown corundum
White corundum, Brown corundum
White corundum, also known as white fused corundum; brown corundum, also known as brown fused corundum. They are a kind of abrasive with aluminum oxide (Al2O3) as the main component. White corundum is usually white, with slightly higher hardness than brown corundum, but slightly lower toughness. Brown corundum is usually brown, with slightly lower hardness than white corundum, but better toughness. White corundum and brown corundum are widely used in grinding, polishing and other processing processes of various materials, as well as casting, refractory materials and ceramics industries.
The following is a detailed point-by-point introduction of white corundum and brown corundum:
Physical properties
1. Hardness: It is a very hard material.
2. Melting point: It is very high and can withstand high temperatures.
Chemical properties
1. Stability: It has good chemical stability and is not easy to react chemically with other substances.
2. Corrosion resistance: It has good corrosion resistance to most acids, alkalis and other chemicals.
Application areas
1. Abrasives and grinding tools: It is suitable for manufacturing various grinding tools, such as grinding wheels, sandpaper, sanding belts, etc.
2. Metal processing: used for metal grinding, polishing and other processing processes.
3. Casting industry: as precision casting sand, it can improve the surface quality of castings.
4. Refractory materials: due to its high temperature resistance, it can be used to make advanced refractory materials.
5. Ceramic industry: used for the production of special ceramics, such as high-aluminum porcelain, engineering ceramics, etc.
6. Others: also used in spraying materials, chemical catalyst carriers and other fields.
Advantages
1. High hardness: suitable for grinding hard materials.
2. Good toughness: not easy to break during the grinding process.
3. Long service life: good wear resistance, long service life of the abrasive.
4. Wide range of applications: can be used for the processing of a variety of materials.
Disadvantages
1. High cost: compared with some other abrasives, the price of white corundum and brown corundum is higher.
2. Difficulty in processing: high hardness makes the processing process more difficult.
In short, white corundum and brown corundum, as a high-performance abrasive, are widely used in the industrial field. Its high hardness, good toughness and strong chemical stability make it an ideal choice for metal grinding, polishing, refractory materials, ceramics and other industries.
