Tabular corundum
Tabular corundum
Tabular corundum is a high-performance ceramic material with a wide range of applications in the industrial field. The following is a detailed introduction and summary of the characteristics, physical properties, chemical properties and industrial applications of tabular corundum:
Features
1. High purity: Tabular corundum is a pure, sintered corundum without any additives, with an Al2O3 content of more than 99%.
2. Good crystal structure: It has a coarse crystal and well-developed a-Al2O3 crystal structure.
3. Excellent physical properties: including high density, high hardness, strong wear resistance, high compressive strength, good high temperature resistance, good insulation performance and good chemical stability.
Physical properties
1. Density: usually between 3.83.9g/cm³, several times higher than general metal materials.
2. Hardness: usually between 9.09.5 levels, harder than traditional metal and plastic materials.
3. Wear resistance: It can withstand a lot of wear and friction, so it is widely used in the production of wear-resistant parts.
4. Compressive strength: able to withstand pressures up to 2000MPa or more.
5. High temperature resistance: can be used for a long time in high temperature environment without degradation.
Chemical properties
1. High refractoriness, high corrosion resistance, high erosion resistance, and high thermal shock stability.
2. Stable chemical properties: not corroded by most acids, alkalis, solvents, etc.
Industrial applications
1. Refractory materials: Plate-shaped corundum can be used to produce various aluminum refractory materials, such as castables, plastics, ramming materials, etc., and are widely used in steel, casting, ceramics and other industries.
2. Machining: As a cutting tool and abrasive material, it can effectively improve processing efficiency, reduce processing costs and extend tool life.
3. Electronic industry: used to manufacture electronic components such as semiconductor materials, capacitors, resistors, insulators, etc., with excellent insulation performance, high temperature resistance and high mechanical strength.
4. Chemical industry: has excellent corrosion resistance, can withstand the erosion of corrosive media such as strong acids, strong alkalis, and high temperatures, and is used to manufacture chemical equipment.
5. Petroleum industry: As a material for oil extraction, processing and storage equipment, it has the characteristics of wear resistance, corrosion resistance, high strength and high temperature stability.
6. Thermoelectric industry: used to manufacture thermoelectric devices such as thermoelectric generators, thermocouples, and thermoelectric coolers, with high temperature stability and excellent thermoelectric properties.
In summary, tabular corundum has broad application prospects in the industrial field due to its high purity and excellent physical and chemical properties.
