Specification of Al2O3 99 High Temperature Refractory Alumina Melting Ceramic Crucible Mullite Crucible

This Al2O3 99 crucible manages severe warm reliably. It’s made from 99% pure alumina ceramic. This ensures high chemical pureness. Your products remain uncontaminated during procedures. The crucible holds up against temperature levels up to 1800 ° C. This makes it best for demanding melting tasks. It likewise withstands thermal shock effectively. Including mullite increases this sturdiness. The crucible will not crack easily with quick temperature level shifts. This is essential for duplicated home heating and cooling cycles.

You obtain outstanding resistance to corrosion. Acids and alkalis will not harm it easily. The crucible framework stays secure gradually. It will not warp or downturn under heavy loads. This crucible fits numerous heating system types. Use it securely in air or inert gas atmospheres. Its high density obstructs slag infiltration. Your melts remain cleaner inside. The smooth surface makes putting easier. Cleaning up after that is less complex also.

These crucibles work for melting metals. Gold, silver, platinum, and copper prevail usages. They are vital in labs for sample preparation. Jewelers count on them for casting precious metals. Shops use them for little alloy batches. They offer well in glass fusing applications. Ceramic powder sintering requires them too. The crucible provides consistent performance. It conserves you money by lasting longer. You prevent constant substitutes. Handling is simple. It fits common furnace arrangements. This crucible is a reliable tool for severe heat work.

Applications of Al2O3 99 High Temperature Refractory Alumina Melting Ceramic Crucible Mullite Crucible

Al2O3 99 heat refractory alumina melting ceramic crucibles are vital devices. They are made primarily from very pure light weight aluminum oxide. This purity is key. It provides the crucible its incredible heat resistance. These crucibles quickly take care of temperatures over 1700 ° C. Several other products would thaw or damage at these heats. They don’t.

These crucibles are developed challenging. They commonly consist of mullite fibers for additional stamina. This makes them much less most likely to crack under sudden temperature modifications. Assume heating up quickly or cooling down quickly. Normal crucibles might shatter. These hold up much better. This strength saves cash. You don’t need to replace them as often.

The high purity alumina product is chemically extremely stable. It resists strike from numerous molten products. This is important. It implies the stuff you thaw inside keeps pure. Contamination from the crucible itself is very little. You obtain reputable outcomes. This matters for specific job like chemical analysis or growing pure crystals.

These crucibles are perfect for demanding jobs. Use them in labs for testing products at extreme warmth. Factories use them to thaw special metals and alloys. Ceramic and glass makers count on them for refining resources. Jewelers use them for rare-earth element spreading. They are essential in research study exploring new high-temperature products. You require a container that won’t fall short. This type of crucible supplies regular efficiency. It holds up against the extreme problems needed for these procedures.

5 FAQs of Al2O3 99 High Temperature Refractory Alumina Melting Ceramic Crucible Mullite Crucible

What’s the max temperature this crucible handles?
It withstands 1800°C (3272°F) constant heat. Short bursts might reach 1850°C. Exceeding 1800°C risks cracking. Always respect the limit. Your melts stay safe.

What materials work best inside?
Use it for melting precious metals like gold or platinum. It handles silver too. Ceramic frits, glass batches, and some high-temp alloys fit. Avoid super corrosive stuff. Alkalis or strong fluxes attack the alumina. Check compatibility first.

Alumina or mullite? Which is stronger?
Alumina wins for pure heat resistance. It’s denser, handles higher temps better. Mullite offers better thermal shock resistance. It copes with sudden temperature changes easier. Choose alumina for extreme, steady heat. Mullite suits repeated heating-cooling cycles.

How do I clean it after use?
Let the crucible cool completely first. Never quench it hot. Gently remove leftover material. Use a soft brush or wooden tool. Avoid metal scrapers. They scratch the surface. For stubborn residue, grind it out carefully. Wash with water if needed. Dry thoroughly before reheating.

How long does one crucible last?
Lifespan varies a lot. Depends on your max temperature, how often you use it, the materials melted. Proper care extends it. Avoid thermal shock. Don’t overheat. Clean gently. Expect many uses under good conditions. Rough handling or extreme temps shorten life fast. No shortcuts here.
