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 Crucible Alumina Ceramic High Refractoriness Alumina Al2O3 Ceramic Crucible

What is an Al2O3 ceramic crucible? An Al2O3 ceramic crucible is a container made from alumina ceramic material. It is designed for high-temperature applications like melting metals or conducting lab experiments. The main component is aluminum oxide (Al2O3), which gives the crucible strong heat resistance. Alumina content typically ranges above 99%, ensuring stability in extreme conditions. This material resists chemical corrosion and thermal shock effectively.

What maximum temperature can it withstand? Al2O3 crucibles handle temperatures up to 1800°C. They remain stable even under rapid heating or cooling cycles. This makes them suitable for industrial furnaces or precision lab work. The high refractoriness prevents deformation or cracking. Proper use ensures long-term performance without degradation.

What are the advantages over other crucibles? Alumina crucibles outperform materials like graphite or quartz. They resist chemical reactions with acids, alkalis, and molten metals. High purity reduces contamination risks in sensitive processes. Their mechanical strength lasts longer under repeated use. Lower replacement frequency makes them cost-effective over time.

What precautions are needed during use? Avoid sudden impacts or drops to prevent cracks. Do not expose hot crucibles to cold liquids directly. Thermal shock weakens the structure. Use tongs or protective gear when handling heated crucibles. Inspect for damage before each use. Store in dry conditions to maintain integrity.

How to select the right Al2O3 crucible? Check the alumina content for your temperature needs. Higher alumina grades suit extreme heat. Match the crucible size and shape to your equipment. Thicker walls improve durability for abrasive materials. Verify compatibility with the substances being melted. Custom designs are available for specialized applications.
