Overview of Corundum Crucible

Corundum crucibles, made from alumina (Al₂O₃), are highly valued for their exceptional thermal resistance and chemical stability. These crucibles are ideal for high-temperature applications, such as melting and annealing processes in laboratories and industrial settings. Corundum crucibles can withstand temperatures up to 1800°C and are resistant to most chemical reagents, making them indispensable in various scientific and manufacturing operations.

Features of Corundum Crucible

High Thermal Resistance: Can withstand temperatures up to 1800°C without degrading.

Chemical Stability: Resistant to most acids and alkalis, ensuring minimal contamination during experiments or production.

Durability: Extremely durable and long-lasting, even under harsh conditions.

Non-Reactive: Does not react with the materials being processed, preserving sample purity.

Versatility: Suitable for a wide range of applications including melting metals, glass, and ceramics.

Precision Engineering: Manufactured to tight tolerances for consistent performance and reliability.

Specification of Factory 99.7% 99% Corundum Alumina Ceramic Crucible Pots for Glass Melting Boat

This alumina ceramic crucible deals with difficult glass melting tasks. It’s made from 99.7% pure diamond alumina. This high pureness matters. It indicates extremely few impurities can enter into your thaw. Your glass stays cleaner. Your outcomes are extra regular.

These crucibles function well at severe warm. They handle temperatures over 1750 ° C quickly. Sudden temperature adjustments won’t fracture them conveniently. This thermal shock resistance is very important. Heating systems heat up and cool down. The crucible needs to manage that stress without breaking.

The material is extremely thick and strong. It stands up to wear from molten glass. The glass doesn’t stick much. This makes cleansing simpler between thaws. You obtain more uses from each crucible. That saves cash with time.

Its chemical security is exceptional. Liquified glass is harsh. This alumina withstands that attack. It won’t react with many glass make-ups. Your melt chemistry stays predictable.

These properties make it best for glass melting boats. It holds molten glass firmly. It gives a steady setting for melting and screening. You require trustworthy tools for consistent glass production. This crucible delivers that dependability. Its long service life minimizes replacement costs. Pick it for requiring lab or small-scale manufacturing melting. It withstands repeated high-temperature cycles effectively. The crucible keeps its shape and integrity.

5 FAQs of Factory 99.7% 99% Corundum Alumina Ceramic Crucible Pots for Glass Melting Boat

Factory 99.7% & 99% Corundum Alumina Ceramic Crucible Pots for Glass Melting – FAQs

1. What’s the difference between 99.7% and 99% alumina?
The number shows the alumina purity. 99.7% alumina is purer. It handles higher temperatures better. It resists chemical attack from molten glass better. It lasts longer under tough conditions. 99% alumina is good. It costs less. It works well for many standard glass melting jobs. Choose 99.7% for top performance and longest life. Choose 99% for good performance at a lower price.

2. How hot can these crucibles get?
These crucibles handle extreme heat. The 99.7% alumina crucibles typically withstand temperatures up to 1750°C (3182°F). The 99% alumina crucibles handle temperatures up to 1650°C (3002°F). Always check the specific grade’s datasheet. Never exceed the maximum rated temperature. Going too hot damages the crucible fast.

3. How long will a crucible last?
Crucible lifespan changes a lot. It depends on the alumina purity. It depends on the melting temperature used. It depends on the type of glass melted. It depends on how often the crucible heats up and cools down. Higher purity alumina usually lasts longer. Softer glasses and lower temperatures are easier on the crucible. Expect many heating cycles with careful use. Harsh conditions shorten the life.

4. Why use alumina ceramic instead of other materials?
Alumina ceramic is excellent for melting glass. It resists very high heat. It doesn’t react with most molten glasses. This keeps the glass pure. It handles sudden temperature changes well. This is important when putting cold glass in or taking hot glass out. Alumina is very hard. It resists wear and erosion. Other materials like graphite can contaminate glass or burn away.

5. What types of glass can I melt in these?
These crucibles work for many common glass types. They handle soda-lime glass well. They handle borosilicate glass well. They handle many lead crystal glasses. They also work for various enamel frits and technical glasses. Avoid glasses with very high levels of strong alkalis or certain fluorides. These can attack the alumina over time. Check compatibility for unusual glass compositions.
