Specifications of BIG size 99% Al2O3/alumina Ceramic Crucibles /BIG CRUCIBLE
Specs of BIG Dimension 99% Al Two O Six Alumina Ceramic Crucibles
Material and Pureness
These crucibles are made from 99% pure alumina (Al ₂ O TWO). The high pureness provides superb resistance to warmth and chemicals. They function well in very hot or corrosive environments where normal ceramics would stop working.
Dimension and Ability
This is a BIG dimension crucible made for large-volume applications. Standard dimensions consist of elevations from 150 mm to 300 mm and sizes from 120 mm to 250 mm. Wall density varies from 8 mm to 15 mm, depending on the model. Custom dimensions are likewise readily available upon request.
Temperature level Resistance
The crucibles can manage continuous use at temperatures approximately 1700 ° C (3092 ° F) . They stay secure even under rapid heating or cooling cycles. This makes them suitable for melting, sintering, and ashing processes in laboratories and industrial setups.
Chemical Stability
Many thanks to the high alumina material, these crucibles stand up to assault from a lot of acids, antacid, and molten metals. They do not react with a lot of products throughout high-temperature handling. This guarantees clean results and long life span.
Mechanical Strength
They have high mechanical toughness and low thermal expansion. This lowers the danger of splitting or deforming during duplicated use. Their dense framework likewise decreases porosity, which aids prevent contamination.
Surface area Complete
Both the inside and outside surface areas are smooth. This finish makes cleaning less complicated and reduces material sticking. Each crucible is carefully checked to meet strict top quality standards prior to shipping.
Common Applications
These BIG crucibles are made use of in metallurgy, glass production, ceramic shooting, and research study laboratories. They are optimal for holding huge samples or batches that need uniform high-temperature therapy.

Applications of BIG size 99% Al2O3/alumina Ceramic Crucibles /BIG CRUCIBLE
Applications of Large 99% Alumina Ceramic Crucibles
High-Temperature Melting and Casting
Huge 99% alumina ceramic crucibles take care of extreme heat without breaking down. They function well for melting steels like gold, silver, platinum, and specialized alloys. Their high purity stops undesirable reactions in between the crucible and molten product. This keeps your end product tidy and consistent.
Crystal Growth Processes
These crucibles are ideal for expanding solitary crystals used in lasers, semiconductors, and optical gadgets. The 99% alumina composition resists chemical assault from hostile thaws like sapphire or yttrium light weight aluminum garnet (YAG). Their large size supports bigger crystal batches, which boosts production performance.
Laboratory and Study Usage
In research laboratories, these crucibles hold samples during high-temperature analysis, ash screening, or combination preparation. Their security approximately 1700 ° C makes them reputable for duplicated thermal cycles. Scientists trust them since they do not infect delicate experiments.
Industrial Warmth Treatment
Industries make use of big alumina crucibles in heating systems for sintering, annealing, or calcining progressed porcelains and powders. The crucibles preserve form and stamina even after long exposure to warm. Their smooth indoor surface assists with very easy product release and cleaning.
Specialized Glass and Fiber Manufacturing
Suppliers thaw specialty glasses– such as borosilicate or optical glass– in these crucibles. The high alumina content protects against leaching right into the melt. That makes certain the glass remains clear and devoid of flaws. Large capability likewise fits continual fiber drawing configurations.
These crucibles combine durability, purity, and thermal efficiency. Their dimension fulfills demands where typical crucibles fall short. Whether you run a laboratory or a factory, a big 99% alumina crucible gives dependable outcomes under hard conditions.

5 FAQs of BIG size 99% Al2O3/alumina Ceramic Crucibles /BIG CRUCIBLE
Frequently Asked Questions About BIG Size 99% Alumina Ceramic Crucibles
What makes these crucibles suitable for high-temperature use?
These crucibles are made from 99% pure alumina (Al₂O₃). This material stays strong and stable even at very high temperatures—up to 1700°C. It does not melt, warp, or break easily under extreme heat. That’s why labs and industries trust them for demanding thermal processes.
Why choose a “BIG” size crucible?
The BIG size holds more material than standard crucibles. This is useful when you need to process large sample batches or run continuous operations. It saves time and reduces the number of runs needed. Bigger capacity also means fewer refills during long experiments or production cycles.
Are these crucibles resistant to chemicals?
Yes. High-purity alumina resists most acids, bases, and molten metals. It won’t react with many aggressive substances used in labs or foundries. However, avoid using hydrofluoric acid or strong alkalis at high temperatures—they can damage the surface over time.
How do I handle and care for these crucibles?
Always let the crucible cool down slowly after heating. Sudden temperature changes can cause cracks. Use clean tongs to move it. Store it in a dry place away from dust or moisture. Do not drop or strike it—it’s strong but still ceramic and can chip if mishandled.
Can I reuse these crucibles?
Absolutely. These crucibles are built for repeated use. After each run, clean off any residue gently. Inspect for cracks or wear before the next use. With proper handling, one crucible can last through many heating cycles without losing performance.
