Specifications of 95 99% Alumina Ceramic Crucible Al2O3 Ceramic Corundum Crucible

These alumina ceramic crucibles are incredibly tough. They handle extreme heat. They are made mostly from aluminum oxide, Al2O3. The purity levels are high, either 95% or 99%. This high purity matters. It gives the crucible its special qualities. The material is called corundum. It is very stable chemically. Acids and alkalis usually don’t affect it much. You can use it with many different chemicals safely. It withstands very high temperatures too. You can heat it well above 1500°C, sometimes near 1800°C. This makes it perfect for melting metals, analyzing minerals, or high-temperature chemistry. It resists thermal shock reasonably well. This means it can handle fast temperature changes without cracking easily. It is much better than some other ceramics here. The crucible is also physically strong. It has good hardness and resists wear. You can use it repeatedly. It won’t degrade quickly. It maintains its shape under stress. The surface is smooth. This helps prevent materials from sticking inside. Cleaning is easier. You find these crucibles in various sizes and shapes. Common forms include tall cylinders or low dishes. Sizes range from tiny ones holding milliliters to larger ones for bigger jobs. They are widely used in labs and industry. People rely on them for demanding heating tasks. Their performance is reliable. They last a long time when used correctly. These crucibles are a solid choice for serious high-heat work.

Applications of 95 99% Alumina Ceramic Crucible Al2O3 Ceramic Corundum Crucible

Alumina ceramic crucibles are essential tools in many industries. They are made from aluminum oxide. This material is incredibly tough. Crucibles come in purity levels like 95% or 99%. Higher purity usually means better performance. These crucibles handle very high temperatures easily. They can withstand sudden temperature changes well. This is called thermal shock resistance. They are also chemically inert. This means they resist corrosion from many acids and bases. They won’t react with most molten materials. This makes them very reliable.

In metal foundries, these crucibles melt metals. They work with iron, steel, copper, and alloys. They are popular for melting precious metals too. Gold and silver smiths use them often. The crucibles don’t add impurities to the melt. They help get pure metal.

Chemical laboratories depend on them. Scientists heat aggressive chemicals inside them. Strong acids or bases don’t damage the crucible material. This allows safe chemical reactions and analysis. Researchers trust them for consistent results.

Material science labs use them extensively. Scientists study new materials at high heat. They might grow crystals or test compounds. The alumina crucible provides a stable, clean environment. It doesn’t interfere with the experiments.

The ceramic is dense and non-porous. This prevents leaks and contamination. Crucibles come in many sizes and shapes. This fits different furnace types and sample amounts. They are reusable many times if handled carefully. This saves money over single-use options. Proper care extends their life significantly. They are a smart investment for demanding thermal applications. Their performance justifies their cost. Industries needing reliable high-temperature containers choose them.

5 FAQs of 95 99% Alumina Ceramic Crucible Al2O3 Ceramic Corundum Crucible

What is an alumina ceramic crucible made of?
Alumina ceramic crucibles are mostly made from aluminum oxide. Aluminum oxide is called Al2O3. High purity alumina is used. The purity level is usually 95% or 99%. This means almost all the material is pure alumina. These crucibles are known as corundum crucibles.

How hot can these crucibles get?
These crucibles handle very high temperatures well. They work fine up to about 1700°C. This is much hotter than many metals melt. This makes them good for melting metals. They also resist sudden temperature changes. This is called thermal shock resistance. You can heat them up fast or cool them down fast. They usually won’t crack from the stress.

Are alumina crucibles strong?
Yes, they are very strong and hard. Alumina is one of the hardest ceramics. This makes them resistant to scratching and wear. They last a long time even with tough use. They keep their shape under high heat and pressure. They do not bend or warp easily. This strength is important for lab work.

How do I clean an alumina ceramic crucible?
Cleaning is usually simple. Let the crucible cool down completely first. Never put a hot crucible in water. That can cause cracking. After cooling, you can wash it with water. Use a brush if needed. For stubborn residues, you might need special cleaning agents. Avoid harsh chemicals that could damage the surface. Always dry the crucible thoroughly before using it again.

What are these crucibles used for?
People use these crucibles for melting metals. They are common in jewelry making. They are also used in laboratories for experiments. They work well with precious metals like gold and silver. They are also good for melting platinum. They are used in chemical analysis. They hold samples that need high heat. Their purity means they won’t add impurities to your melt.
