Overview of Mullite Crucible

Mullite crucibles are made from a high-performance ceramic material composed primarily of alumina (Al₂O₃) and silica (SiO₂). Known for their excellent thermal stability and mechanical strength, mullite crucibles are widely used in high-temperature applications such as melting metals, glass, and ceramics. They offer superior resistance to thermal shock and chemical attack, making them indispensable in both laboratory and industrial settings.

Features of Mullite Crucible

Thermal Shock Resistance: Exceptional ability to withstand rapid temperature changes without cracking.
High Mechanical Strength: Strong and durable, even at elevated temperatures.
Chemical Stability: Resistant to most chemicals, ensuring minimal contamination during processes.
Temperature Range: Can operate effectively at temperatures up to 1650°C.
Low Thermal Expansion: Minimal expansion or contraction with temperature changes, ensuring dimensional stability.
Non-Reactive: Does not react with the materials being processed, preserving sample purity.
Versatility: Suitable for a wide range of applications including metallurgy, glass manufacturing, and laboratory experiments.

5 FAQs of Refractory 5ml 25ml 50ml 100ml 300ml al2o3 alumina ceramic melting crucible with cap lid

Refractory Alumina Ceramic Crucible FAQs

What temperature can these crucibles handle?
These alumina crucibles withstand high heat. They work up to 1750°C (3182°F) continuously. They handle short peaks near 1800°C (3272°F). This covers most melting jobs. Check your specific material’s melt point first. Never exceed 1800°C.

Do I need the cap lid during melting?
Use the cap lid carefully. It traps heat and prevents spills or contamination. This is good for some melts. But, some materials release gas or expand. Pressure could build inside. Assess your material. If gas release is possible, melt without the lid. Place the lid nearby to cover after melting.

Are these crucibles resistant to chemicals?
Yes, alumina ceramic resists many chemicals well. It handles strong acids and alkalis better than metals. It works with molten salts too. Avoid hydrofluoric acid (HF). HF attacks alumina. Avoid strong phosphoric acid hot. Check chemical compatibility for safety.

Can these crucibles handle sudden temperature changes?
Alumina ceramic handles thermal shock reasonably well. It’s better than many ceramics. Still, avoid extreme changes. Never put a hot crucible directly on a cold surface. Don’t plunge a hot crucible into water. Let it cool slowly inside the furnace. Pre-heat the crucible gradually with the furnace.

How many times can I reuse one crucible?
Reuse depends heavily on use. Factors include temperature, material melted, and cooling speed. Used gently, a crucible lasts many cycles. Inspect it closely before each use. Look for cracks, chips, or deep erosion. Stop using it if you see damage. Damaged crucibles can fail suddenly. This is dangerous.
