Introduction to Alumina Ceramics

Alumina ceramics are known for their high hardness, wear resistance, corrosion resistance, good electrical insulation and high temperature stability. According to the different alumina content, it can be divided into different grades, such as 95 porcelain, 99 porcelain, etc., among which 99 porcelain refers to ceramic materials with an alumina content of 99%. As the alumina content increases, its mechanical strength and electrical insulation properties will also increase accordingly.

Characteristics of Alumina Ceramics

High Hardness: Alumina ceramics have extremely high hardness, which makes it very wear-resistant and suitable for manufacturing abrasive tools and parts that require wear resistance.

Wear resistance: Due to its high hardness, alumina ceramics show excellent wear resistance and are suitable for manufacturing parts for long-term use.

Corrosion resistance: Alumina ceramics have good resistance to most acids and alkalis, making them widely used in the chemical industry.

Good electrical insulation: As an excellent electrical insulating material, alumina ceramics are widely used in electronic and electrical products.

High temperature stability: Ability to withstand extremely high temperatures without significant physical or chemical changes, which makes it an ideal choice for applications in high temperature environments.

Biocompatibility: In the medical field, certain grades of alumina ceramics are used to make medical devices such as artificial joints due to their good biocompatibility.

5 FAQs of Al2O3 Ceramic HIgh Temperature Thermal Alumina Ceramic Crucible for

Al2O3 ceramic high-temperature thermal alumina ceramic crucibles handle extreme heat. People ask common questions. Here are answers. What are these crucibles used for? They work in labs, factories, metal melting, glass making, and chemical testing. They hold materials heated above 1500°C. They resist reactions with acids, bases, and molten metals. They suit repeated high-heat tasks. How hot can they get? Alumina ceramic crucibles withstand up to 1800°C. Exact limits depend on purity. Higher alumina content (99%+) improves heat resistance. They stay stable in rapid temperature changes. Avoid sudden cooling to prevent cracks. Are they better than graphite or quartz crucibles? Alumina lasts longer under chemical stress. Graphite wears faster in oxidizing settings. Quartz cracks easier under thermal shifts. Alumina resists corrosion from fluxes and melts. It handles harsh conditions without degrading. How do you clean them? Use mild soap and water after cooling. Remove stuck residue with diluted acid or alkali. Avoid abrasive scrubbing. Dry completely before reheating. Thermal shock weakens them. Do not expose hot crucibles to cold liquids. Check for cracks after cleaning. What should buyers check before purchasing? Confirm alumina content (95% to 99.9%). Higher purity means better performance. Match size and shape to your furnace or setup. Check wall thickness for heat distribution. Verify chemical compatibility with your materials. Compare prices based on quality. Cheap options may fail under stress. Reliable suppliers provide test data.
