Specifications of High Temperature 99.7% Al2O3 Alumina Ceramic Corundum Crucibles Industrial Ceramic Application Bending Cutting Processing

These crucibles are made from very pure alumina ceramic. The material is 99.7% Al2O3. This high purity gives excellent performance. They handle extreme heat well. The maximum continuous use temperature is 1750°C. Short-term use can reach 1800°C. They handle sudden temperature changes well. This is thermal shock resistance. It is important for industrial heating and cooling cycles.

The material is dense and hard. Density is around 3.9 g/cm³. This high density stops gases and liquids from leaking through. It also makes the crucibles last longer. They resist chemical attack strongly. Acids and alkalis generally do not damage them. This is vital for melting metals and chemical processes. They are good for platinum, gold, and other precious metals. They work well in catalyst production and powder calcination.

These crucibles are strong. They have high mechanical strength. This strength resists bending forces. The material maintains its shape under load. This is bending strength. It prevents cracking during use. The material is also very hard. Hardness is near Mohs 9. This hardness resists scratches and wear. It extends the crucible’s life in rough conditions.

The alumina ceramic is suitable for precise machining. Cutting and shaping it is possible. This allows custom sizes and shapes. It can be machined to tight tolerances. This is important for specific industrial setups. The material is electrically insulating. It is stable in oxidizing and reducing atmospheres. This versatility suits many furnace types. These crucibles are essential tools for high-temperature labs and industry. They handle demanding processes reliably. They are used in research, development, and production.

Applications of High Temperature 99.7% Al2O3 Alumina Ceramic Corundum Crucibles Industrial Ceramic Application Bending Cutting Processing

These crucibles made from 99.7% pure alumina ceramic, known as corundum, handle extreme heat exceptionally well. They withstand temperatures up to 1800°C reliably. This makes them vital across many tough industrial processes needing pure, stable containers. Their near-perfect purity means they introduce almost no contamination. This is critical for precise work.

Metal foundries use them constantly for melting alloys. They survive the intense heat and corrosive nature of molten metals like platinum, palladium, and rare earths. Glass manufacturers also depend on them. They hold molten glass for forming without degrading or adding unwanted elements. Chemical labs need them too. They perform high-purity chemical analysis and synthesis without reacting with the substances inside.

The semiconductor industry relies heavily on these crucibles. They process ultra-pure silicon and other materials essential for making chips. Their stability is non-negotiable here. Thermal processing of advanced ceramics often happens inside them. They provide the clean, high-temperature environment required.

Beyond containing materials, these alumina ceramic crucibles themselves need shaping and finishing. Their exceptional hardness allows precise bending and cutting operations. Specialized diamond tools are used for this machining. This enables custom crucible designs for specific furnaces or unique experimental setups. The material resists chipping and cracking during this careful processing. This toughness ensures the final crucible performs reliably under severe thermal stress and repeated thermal cycling. Factories appreciate their long service life and resistance to thermal shock. This reduces downtime and replacement costs significantly. They offer a dependable solution for demanding high-heat applications.

5 FAQs of High Temperature 99.7% Al2O3 Alumina Ceramic Corundum Crucibles Industrial Ceramic Application Bending Cutting Processing

What makes these crucibles handle extreme heat?
The 99.7% alumina purity is key. This high purity creates a strong corundum structure. This structure resists melting incredibly well. These crucibles reliably withstand temperatures exceeding 1700°C. They handle sudden temperature changes well too.

Why is 99.7% purity so important?
Impurities weaken ceramics. They lower the melting point. They make the material less stable under heat and chemical attack. Our 99.7% Al2O3 minimizes these impurities. This ensures maximum resistance to molten metals, salts, and aggressive chemicals. You get fewer reactions contaminating your melt.

Can these crucibles be machined or cut?
Yes, but it requires special tools and methods. Alumina ceramic is very hard. Standard steel tools won’t work. Diamond grinding wheels or laser cutting are necessary. Experienced technicians must do this work. Handle the crucibles carefully during any machining. Brittle materials can crack.

What happens if a crucible gets a crack?
Cracks are a serious problem. They compromise the crucible’s strength and safety. A cracked crucible can fail suddenly under heat. This risks spillage of hot materials. It can damage equipment. It creates a safety hazard. Never use a crucible with any visible cracks or chips. Replace it immediately.

Are these crucibles good for repeated heating cycles?
Yes, their thermal shock resistance helps a lot. They manage rapid heating and cooling cycles better than lower purity ceramics. This reduces stress buildup. Expect a longer service life with proper care. Avoid extreme, uneven heating. Follow recommended heating and cooling rates. This maximizes their lifespan in furnaces or kilns.
