Specification of The Supplies 99% Alumina Ceramic Crucibles High Temperature Resistant Ceramic Crucibles

Specification of The Supplies 99% Alumina Ceramic Crucibles High Temperature Resistant Ceramic Crucibles.

These crucibles are made from 99% pure alumina ceramic. This high purity is key. It gives them excellent resistance to very high temperatures. They can handle continuous use up to 1650°C (3000°F). Short-term use can reach even higher, around 1700°C (3100°F). This makes them perfect for intense heating applications.

They are very strong. The material has high mechanical strength. It resists wear and abrasion well. This toughness means the crucibles last a long time. They withstand rough handling better than lower purity ceramics.

Thermal shock resistance is another major feature. These crucibles heat up and cool down without cracking easily. Sudden temperature changes are less of a problem. This is because alumina has low thermal expansion. They expand very little when heated. This reduces internal stress during rapid heating or cooling cycles.

Chemical stability is outstanding. The 99% alumina ceramic resists attack from many acids and alkalis. It doesn’t react with most molten metals or slags. This inertness keeps your samples pure. Contamination is minimized. Chemicals don’t damage the crucible easily.

The crucibles have a very dense structure. Porosity is extremely low. This prevents materials from soaking into the crucible walls. It also makes cleaning easier after use. Leakage is virtually eliminated.

Surface finish is smooth. This further helps prevent material sticking. It aids in pouring melts cleanly. Cleaning residue off is simpler.

They come in many sizes and shapes. Common sizes range from small 10ml capacities up to large 500ml or more. Standard shapes include tall form, low form, and sometimes special designs. Dimensions are precise. This ensures consistent performance.

These crucibles are ideal for repeated high-heat use. They work well in labs, research, and industrial processes like metal melting, ash testing, or chemical synthesis.

Applications of The Supplies 99% Alumina Ceramic Crucibles High Temperature Resistant Ceramic Crucibles

These 99% alumina ceramic crucibles handle extreme heat reliably. They work perfectly for melting metals. Gold, silver, copper, platinum need containers that won’t fail. These crucibles resist temperatures over 1700°C. This makes them safe for foundries and jewelry workshops. You can melt metal repeatedly. The crucible won’t crack or contaminate your melt. This purity is crucial for high-quality results.

Chemical processing uses these crucibles too. They hold aggressive acids and bases. Fusions, ashing, and calcination demand inert containers. Alumina offers excellent chemical resistance. Your samples stay uncontaminated. Reactions proceed without unwanted interference from the crucible material.

Laboratories depend on them for precise work. They are essential for sample preparation. Analytical testing requires pure starting materials. These crucibles ensure no impurities skew results. Materials science research uses them constantly. They synthesize new compounds at high temperatures. Crystal growth experiments need stable, inert platforms. Alumina crucibles provide that stability.

The high purity alumina minimizes interaction. Your molten material stays true to its composition. This is vital for accurate analysis and production. The crucibles offer great thermal shock resistance. You can heat and cool them rapidly. They won’t break under sudden temperature changes. This durability saves time and money. You get many uses from each crucible.

Industrial furnaces rely on their strength. They withstand harsh conditions daily. Production processes need dependable equipment. These crucibles deliver consistent performance. They are the go-to choice for demanding high-temperature tasks. Their reliability is proven across many fields.

5 FAQs of The Supplies 99% Alumina Ceramic Crucibles High Temperature Resistant Ceramic Crucibles

What makes these crucibles handle high heat?
They are made from 99% pure alumina. Alumina ceramic is very stable. It doesn’t melt easily. These crucibles withstand temperatures up to 1700°C. This is much hotter than most metals can handle. They keep their shape and strength at these extremes.

Why is 99% alumina purity important?
Higher purity means fewer impurities. Impurities weaken the material. They make the crucible more likely to crack under heat. 99% alumina gives maximum resistance to heat and chemicals. It ensures the crucible doesn’t react with your materials. Your sample stays pure.

Can these crucibles handle sudden temperature changes?
They resist thermal shock better than lower purity ceramics. But you must be careful. Avoid very rapid heating or cooling. Big, fast temperature swings stress any ceramic. Heat them up gradually. Let them cool down slowly too. This makes them last much longer. Don’t plunge a hot crucible into cold water.

What are they typically used for?
These crucibles are for labs and industry. People use them for melting metals like gold or silver. They work for fusing samples in analysis. They are good for sintering powders. They work well in high-temperature furnaces. They are not for direct flame contact.

How do I clean them after use?
Let the crucible cool completely first. Remove loose residue physically. Soak it in a suitable acid or solvent bath if needed. Alumina resists most chemicals. Rinse it very well with clean water after soaking. Dry it thoroughly before reusing. Avoid harsh mechanical scrubbing. It can scratch the surface over time.
