Specifications of Factory 99.7% 99% Corundum Alumina Ceramic Crucible Pots for Glass Melting Boat

These Manufacturing facility 99.7% Alumina Porcelain Crucible Pots are built for hard glass melting work. They use very high-purity alumina (light weight aluminum oxide). This purity degree is 99.7%. It means the crucible takes care of extreme warmth truly well. You obtain exceptional resistance to high temperatures. The material likewise fights off chemical deterioration effectively. Glass thaws will not damage it easily. These crucibles are recognized for lasting a long period of time.

The crucible shape is a timeless boat layout. This shape is practical. It provides you an excellent surface area for melting. It also makes pouring melted glass easier. Requirement dimensions are offered. Usual measurements are around 150mm long, 100mm wide, and 80mm high. Wall thickness is commonly 10mm. This thickness provides toughness. It additionally assists handle heat appropriately. You can get other sizes if needed.

Thermal shock resistance is a vital function. The crucible warms up quickly. It cools down fast also. Abrupt temperature adjustments will not crack it. This is essential for glass job. Processes frequently entail quick home heating or cooling down cycles. The dense ceramic structure reduces contamination. Your dissolved glass stays pure. You will not obtain undesirable stuff from the crucible blending in.

These crucibles function well in electric kilns or gas heaters. They deal with temperature levels as much as 1700 ° C (3092 ° F) conveniently. This covers a lot of glass melting requirements. The material is really difficult. It withstands wear and abrasion. This sturdiness indicates you use it over and over. It saves money lasting. Handling is simple. The layout is basic and robust.

Manufacturing facilities rely on these crucibles for regular outcomes. The high purity alumina makes certain dependable efficiency thaw after thaw. It’s a strong option for major glass melting.

Applications of Factory 99.7% 99% Corundum Alumina Ceramic Crucible Pots for Glass Melting Boat

These crucible pots are made from 99.7% pure alumina ceramic. This is corundum. It’s unbelievably tough and durable. Glass manufacturers use them for melting glass. They manage the intense heat very well. Temperature levels reach 1800 ° C quickly. The material stays steady. It doesn’t soften or warp. This stability is vital for regular melting.

The pureness is crucial. 99.7% alumina suggests very few impurities. Impurities can wreck the glass thaw. They cause problems or discoloration. These pots maintain the glass tidy. You get a pure melt each time. The surface is very smooth also. Liquified glass does not adhere to it. This makes putting less complicated. Cleansing the pot is less complex after usage.

Thermal shock resistance is another large and also. These pots heat up quick. They cool off quick too. They do not split from sudden temperature adjustments. This prevails in glass workshops. Frequent heating and cooling down cycles take place. Normal crucibles could break. These alumina pots endure it. Their low porosity helps. Less than 1% porosity implies practically no glass seeps in. The crucible stays intact longer. Its life expectancy is much better.

Manufacturing facilities create these crucibles exactly. They make certain consistent wall surface thickness. This advertises also warm distribution. Locations are minimized. The glass thaws evenly. You stay clear of uneven melting troubles. The form is developed for performance. The “boat” type holds an excellent quantity of material. It fits basic melting setups well.

These crucibles are crucial devices. They are for melting high-quality glass. Jewelers, artists, and laboratories rely on them. They need reputable, high-purity melting containers. These alumina pots provide that. They provide outstanding efficiency. They last a long period of time. This minimizes substitute expenses substantially. Taking care of molten glass needs trustworthy devices. These crucibles supply that stability.

5 FAQs of Factory 99.7% 99% Corundum Alumina Ceramic Crucible Pots for Glass Melting Boat

Factory FAQs: 99.7% Alumina Ceramic Crucible Pots for Glass Melting

What material are these crucibles?
These crucibles are made from 99.7% pure alumina ceramic. This is a very hard material. It’s mainly corundum. This gives excellent resistance to heat and chemicals.

How hot can these crucibles get?
These crucibles handle very high temperatures well. The maximum continuous use temperature is 1750°C (3182°F). Short peaks can reach 1800°C (3272°F). Do not exceed these limits. Exceeding them damages the crucible.

How long does one crucible last?
Crucible lifespan varies. It depends heavily on your specific melting process. Factors include the glass type melted, the temperature used, how long each melt cycle runs, and how carefully you handle the crucible. Expect multiple uses under normal conditions. Inspect it regularly for cracks or wear.

Do I need to preheat new crucibles?
Yes, preheat new crucibles slowly before first use. This step is critical. It removes any absorbed moisture from the ceramic material. Heating too fast traps steam. Trapped steam causes cracking. Follow the factory’s recommended preheating schedule exactly.

How can I prevent thermal shock?
Avoid sudden, extreme temperature changes. Never place a cold crucible directly into a hot furnace. Never pour cold material onto a very hot crucible. Allow the crucible to heat up and cool down gradually. Control temperature changes during operation. This prevents cracking from thermal stress.
