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.

Specifications of Labor Al2O3 Ceramic Crucible 95 Alumina Ceramic Crucible

This Labor Al2O3 Ceramic Crucible uses 95% alumina. This high purity makes it strong. It handles very high temperatures well. You can use it up to 1650°C (3000°F). This crucible resists sudden temperature changes. It doesn’t crack easily going from hot to cold. The material fights chemical attack. Acids and bases won’t harm it much. This crucible lasts a long time. It won’t wear out quickly.

The crucible comes in different sizes. Common capacities are 10ml, 20ml, 50ml, 100ml. You can find larger sizes too. The shape is usually a standard dish. The surface is smooth inside. This stops material from sticking. The outside might be slightly rougher. This makes it easier to hold. The walls are thick enough. They provide good strength. The bottom is flat. This gives stable heating.

People use this crucible in labs. It’s good for melting metals. It works for melting glass frit. People use it for ashing samples. It handles sintering powders. The crucible works in furnaces. It works in kilns. It works for calcination. Industries use it for testing materials. Jewelers use it for small melts. It’s common in research. It’s common in quality control.

Handle the crucible carefully. Avoid hitting it hard. It can break from impact. Don’t heat it too fast. Let it warm up slowly. Let it cool down slowly. This prevents stress cracks. Keep it clean between uses. Follow the maker’s instructions. This ensures the best performance.

Applications of Labor Al2O3 Ceramic Crucible 95 Alumina Ceramic Crucible

Labor Al2O3 ceramic crucibles, specifically the 95% alumina type, serve critical roles in demanding high-temperature work. They are essential tools across many industries. These crucibles handle extreme heat extremely well. They withstand temperatures from 1700°C to 1800°C easily. This high heat tolerance is crucial for melting metals. You find them melting gold, silver, copper, and various alloys. The 95% alumina composition provides excellent chemical stability. It resists attack from many molten materials. This fights corrosion effectively. Samples stay pure. Contamination risks drop significantly.

These crucibles are physically strong. They possess high mechanical strength. This toughness handles the rough conditions inside furnaces. Thermal shock resistance is another key benefit. Crucibles heat up fast. They cool down fast too. Sudden temperature changes won’t crack them easily. This strength ensures they last long. You get reliable performance over many uses. This durability saves money. Replacement costs go down.

Industrial labs use them constantly. They are vital for precise chemical analysis. Sample preparation needs clean, inert containers. These crucibles deliver that. The purity of the alumina matters. It prevents unwanted reactions. You see minimal interaction with samples. Results stay accurate. Metallurgical processes rely on them heavily. Metal refining happens inside them. They contain the molten metal safely. Foundries use them daily. They are also common in materials research. Scientists test new compounds at high heat. They need dependable crucibles. The 95% alumina type is the standard choice. Glass manufacturing uses them too. They handle molten glass mixtures reliably. Ceramic production employs them for firing special materials.

5 FAQs of Labor Al2O3 Ceramic Crucible 95 Alumina Ceramic Crucible

Labor Al2O3 Ceramic Crucible 95 Alumina Ceramic Crucible FAQs:

What is this crucible made of?
It uses 95% aluminum oxide. This material is very strong. It resists chemicals well. It handles high heat without breaking.

What temperatures can it handle?
It works up to 1650°C continuously. It survives short bursts near 1800°C. Avoid sudden temperature changes. These might cause cracks.

How do I clean it after melting metals?
Let it cool down first. Scrub off residue gently with sand or a soft brush. Never use harsh chemicals. They damage the surface. Rinse with water only. Dry it completely before reuse.

Can I melt all metals in it?
It works for gold, silver, copper, and platinum. Avoid iron, nickel, or alloys with them. These metals react badly. They stick to the crucible. They ruin it fast.

Why pick 95% alumina over cheaper options?
Higher alumina means longer life. It handles more melts. It resists corrosion better. It saves money over time. Cheap crucibles crack sooner. They cost more in replacements.
