Specification of High Purity Alumina Ceramic Boat Pot High Temperature Fireclay Crucibles for Furnace at a Great Refractory Ceramic Plates

Our high purity alumina ceramic crucibles offer top performance for demanding furnace applications. These crucibles are crafted from premium fireclay. They contain over 99.5% pure alumina. This purity ensures exceptional chemical resistance. They resist attack from strong acids, alkalis, and molten metals very well. These crucibles handle extreme heat. They withstand temperatures exceeding 1700°C continuously. They manage short bursts even higher. Thermal shock resistance is excellent. They handle sudden temperature changes without cracking. This is vital for many lab and industrial processes.

The ceramic material provides outstanding structural integrity. It stays strong under heavy loads at maximum temperature. Crucible walls are dense and non-porous. This prevents contamination of your materials. It also stops furnace gases from affecting your samples. These boats and pots are designed for long service life. They resist wear and corrosion exceptionally well. They outlast many standard crucibles significantly. This saves money over time.

These crucibles work in many furnaces. They are ideal for tube furnaces, muffle furnaces, and kilns. Common uses include sintering, annealing, and calcination. They work for melting precious metals and growing crystals too. Their high purity is critical for semiconductor processing. It prevents unwanted doping of silicon wafers. The smooth surface allows easy sample removal. Cleaning is simple after use.

Our refractory ceramic plates complement these crucibles perfectly. They are made from similar high-grade alumina. They offer the same thermal stability and chemical resistance. The plates provide a stable, inert surface inside your furnace. They protect the furnace floor from spills and drips. They extend the furnace’s lifespan. Using our plates with our crucibles creates a reliable high-temperature setup.

5 FAQs of High Purity Alumina Ceramic Boat Pot High Temperature Fireclay Crucibles for Furnace at a Great Refractory Ceramic Plates

People need reliable crucibles for high-temperature work. These alumina ceramic boats and fireclay pots are popular choices. Here are answers to common questions.

What material are these crucibles? They are made from high-purity alumina ceramic or special fireclay. Alumina offers great chemical resistance. Fireclay provides good thermal shock resistance. Both materials are very dense and durable. They resist melting and corrosion well.

How hot can these crucibles get? Alumina ceramic crucibles handle temperatures up to 1750°C. Fireclay crucibles typically manage up to 1400°C. Check the specific product details. Never exceed the maximum rated temperature. Doing so damages the crucible quickly.

How do I clean them after use? Let the crucible cool completely first. Never quench hot crucibles in water. Thermal shock cracks them. Remove residue with a scraper or stiff brush. Avoid harsh chemicals unless specified. Sometimes high-temperature burning off residue works. Rinse thoroughly with water if needed. Dry completely before reuse.

How long do these crucibles last? Crucible lifespan varies a lot. It depends on operating temperature, thermal cycling, materials processed, and handling. Gentle heating and cooling cycles help. Avoid sudden temperature changes. Proper cleaning prevents buildup. Inspect crucibles regularly for cracks or wear. Replace them when damaged.

What sizes and shapes are available? Many sizes exist. Boat shapes are common. Round pots are standard. Rectangular plates are available too. Dimensions vary by model. Check the product listings carefully. Ensure the size fits your furnace and holds your sample amount. Custom shapes might be possible. Ask the supplier directly.
