Applications of High 99 Alumina Corundum Ceramic Crucible

High 99 Alumina Diamond Ceramic Crucibles are vital devices. They deal with extreme warm well. They work reliably above 1800 ° C. This makes them ideal for melting steels. Platinum, palladium, and gold need these temperatures. Labs utilize them constantly for this. The crucibles withstand chemical assault strongly. Acids and bases do not harm them conveniently. This security is crucial for chemical synthesis. Scientist mix responsive compounds inside them safely. Powder handling needs resilient containers. These crucibles calcine products without contamination. They maintain powders pure during high heat therapy.

Semiconductor producing needs severe purity. Alumina crucibles meet this demand. They present minimal impurities. This is critical for expanding crystals. It’s key for refining silicon wafers. Their thermal shock resistance is great. They endure quick temperature level adjustments. Moving from a warm heater to cooling down occurs. The crucible does not split. This reliability conserves time and money. Architectural stability issues under lots. These crucibles hold liquified product without warping. They do not sag or break suddenly. Handling heavy thaws is more secure.

Product analysis calls for specific tools. Thermogravimetric evaluation (TGA) utilizes these crucibles. They supply a stable sample atmosphere. Accurate weight dimensions at high warmth depend on it. Luster frit production utilizes them. They hold up against the melting procedure regularly. The crucibles last a long time. They outlive less expensive options considerably. This minimizes substitute regularity. General costs go down. Their inertness safeguards sample integrity. Responses between sample and crucible are unusual. Test results stay true. These properties make them crucial across many demanding areas. The semiconductor industry relies upon them greatly.

5 FAQs of High 99 Alumina Corundum Ceramic Crucible

People often ask about our High 99 Alumina Corundum Crucibles. Here are the top five questions:

What does “High 99 Alumina” mean? It means the crucible is made from over 99% pure aluminum oxide (Al2O3). This high purity makes it very strong and resistant to heat and chemicals. It’s much better than crucibles with lower alumina content.

How hot can this crucible get? This crucible handles extremely high temperatures well. It works perfectly up to 1750°C (3182°F). It can manage short bursts even hotter. It won’t crack or melt under normal lab or industrial furnace conditions. It’s built for super hot work.

What jobs is this crucible good for? You use it for melting metals like gold, silver, platinum, and some alloys. It’s also excellent for fusing powders, analyzing ash content, and heat treating small samples. Any process needing a tough, inert container for hot materials fits.

Will chemicals damage the crucible? High 99 Alumina is very resistant. It stands up well to strong acids, strong bases, and most molten salts. It won’t leak or react with the materials inside under normal use. This keeps your melts pure and uncontaminated.

How careful do I need to be handling it? Handle it gently. Alumina is hard but can crack if dropped or hit hard. Avoid sudden big temperature changes. Don’t heat it up too fast or cool it down too quickly. Always let it warm up slowly and cool down slowly. This prevents thermal shock cracks. Use proper tongs designed for crucibles.
