Specification of C799 Al2o3 99.7% 99% Alumina Ceramic Crucible for Glass Melting Pot

This ceramic crucible handles extreme heat. It resists chemical damage. People use it for melting glass. The material is aluminum oxide. We call it alumina. The purity level is 99.7%. This high purity matters. It makes the crucible very durable. It also helps the crucible resist corrosion. You can use it at very high temperatures. It tolerates temperatures up to 1750°C. That’s 3182°F. This crucible handles sudden temperature changes well. It won’t crack easily. The material is very dense. Its density is about 3.9 g/cm³. That density stops molten material from soaking in. The crucible stays strong. Its hardness is high. It measures 9 on the Mohs scale. This hardness resists scratches and wear. The crucible surface stays smooth. It comes in different sizes. Common sizes are 50 ml, 100 ml, 250 ml, 500 ml, 1000 ml, 2000 ml. You choose the size for your furnace. The crucible shape is cylindrical. It has a flat bottom. The walls are straight. This shape helps heat spread evenly. The design is simple. It works reliably. This crucible suits many applications. Use it for glass melting. Use it for enamel frits. Use it for precious metal melting. Use it for lab tests needing pure alumina. Its high purity ensures no contamination. Your melt stays clean. The crucible lasts a long time. It saves you money. You replace it less often. Handle it carefully. Avoid sharp impacts. Thermal shock is minimized. Still, heat it gradually. Cool it down slowly too. This extends its life. This crucible is a dependable tool. It performs well in harsh conditions.

Applications of C799 Al2o3 99.7% 99% Alumina Ceramic Crucible for Glass Melting Pot

C799 Al2O3 99.7% alumina ceramic crucibles are built tough for melting glass. Their high purity matters. At 99.7% Al2O3, these crucibles withstand extreme heat. They work well above 1700°C. This is crucial for glass melting. High temperatures won’t damage them easily.

These crucibles resist chemical attack. Molten glass is highly corrosive. The dense alumina structure fights this. Impurities stay out of your melt. Your glass stays pure. Consistent results are easier. Glass sticks less. Cleaning is simpler. Crucible life gets longer.

Thermal shock is a big problem in glass work. Crucibles heat up fast. They cool down fast sometimes. Alumina ceramic handles this well. Its low thermal expansion helps. Sudden temperature changes cause less stress. No sudden failures. Your process stays reliable. Downtime drops.

Mechanical strength is excellent. Alumina ceramic is very hard. Crucibles resist scratching. They resist wear over time. Handling molten glass is rough. Crucibles keep their shape. They don’t deform under load. Crucible lifespan increases significantly. You save money on replacements.

Using C799 crucibles means better glass quality. They prevent contamination. Your melt stays clean. You get consistent results batch after batch. This purity is essential for clear glass. It’s vital for colored glass too. Impurities ruin color. Alumina prevents that.

These crucibles work in many furnaces. Electric furnaces use them. Gas furnaces use them. They are versatile. Their performance is reliable. Production becomes smoother. You face fewer interruptions. Consistent glass quality is the result.

5 FAQs of C799 Al2o3 99.7% 99% Alumina Ceramic Crucible for Glass Melting Pot

C799 Al2O3 99.7% Alumina Ceramic Crucible: Key Questions

What is this crucible made from?
This crucible uses very pure alumina ceramic. Its composition is 99.7% aluminum oxide (Al2O3). This high purity level is essential. It ensures strong performance under extreme heat.

How hot can this crucible get?
This crucible handles very high temperatures well. Its maximum working temperature reaches 1750°C (3182°F). This makes it suitable for melting many materials needing intense heat.

Can it handle sudden temperature changes?
Yes, thermal shock resistance is a key strength. Pure alumina ceramic handles rapid heating and cooling cycles effectively. This crucible won’t easily crack from sudden temperature shifts during glass work.

Is it good for melting glass specifically?
Absolutely. Its high purity alumina construction is ideal for glass melting. The material resists reacting with molten glass. This keeps your glass batch clean and free from contamination. It also withstands the chemical nature of molten glass well.

How long will this crucible last?
Lifespan varies based on use. Factors matter a lot. These include the specific glass type melted, peak temperatures reached, heating/cooling speed, and crucible handling. Proper care extends its usable life significantly. Expect good service life under normal glass melting conditions.
