Specifications of High Temperature of The Sagger Box Rectangle Alumina Crucible Ceramic Refractory Crucible Boat

This alumina crucible boat handles severe warmth. It’s produced labs and sector. The shape is rectangular. This shape fits well in numerous heaters. It holds products during heat procedures.

The major material is high-purity alumina ceramic. Alumina is very solid. It resists chemical strike well. This crucible won’t respond with the majority of samples. That maintains your products pure. The alumina is thick. Thickness stops gases and fluids from saturating through. Your examples remain had.

Its optimum continuous temperature is 1750 ° C(3182 ° F). That’s very warm. It helps short bursts at 1800 ° C (3272 ° F). Constantly inspect your details furnace limitations. Thermal shock resistance is good. It takes care of rapid heating and cooling down cycles reasonably well. Prevent severe temperature jumps frequently. This helps the crucible last longer.

Requirement dimensions are common. Lengths are usually 70mm, 90mm, 100mm, 130mm, 150mm, 170mm, 200mm. Widths are normally 15mm, 20mm, 30mm, 40mm, 50mm. Heights are generally 15mm, 20mm, 25mm, 30mm, 40mm. Personalized sizes are possible. Ask the producer. The wall surfaces are thick sufficient for stamina. Density ensures stability at heats.

It’s made for sagger boxes. The watercraft sits inside the safety sagger. This arrangement shields it from straight fire or fumes. This crucible operates in air environments. It works in inert gases also. It’s used for sintering, calcination, and warmth therapy. It benefits evaluating powders, ceramics, metals, and stimulants. It’s reliable for duplicated high-heat usage. Manage it thoroughly. Avoid impacts when cold. Alumina can chip if gone down. Clean it completely between usages. Comply with the producer’s cleansing guidelines. This crucible supplies regular high-temperature performance.

Applications of High Temperature of The Sagger Box Rectangle Alumina Crucible Ceramic Refractory Crucible Boat

This alumina crucible watercraft deals with extreme warmth well. Individuals use it in numerous warm industrial work. It shields materials inside during firing or melting. The shape is rectangle-shaped. This shape fits well in kilns and heating systems.

Ceramic makers depend on it greatly. They placed pottery pieces inside the sagger box. The box guards the ceramic from direct flame and ash. This keeps the pottery tidy throughout glazing. It avoids damage from irregular home heating. Kiln shelves stay cleaner also.

Steel employees utilize it for thawing little steel sets. It holds rare-earth elements like silver or gold safely. The crucible watercraft resists the molten metal’s assault. It doesn’t infect the steel melt. Shops use it for testing tiny alloy examples.

Heat treatment stores find it helpful. They place small metal components inside the boat. The boat goes into high temperature heating systems for annealing or solidifying. The alumina material holds up against rapid temperature modifications. It does not crack easily under thermal shock.

Chemical laboratories and factories use these boats. They hold powders or examples for heat responses. The alumina stays inert. It does not respond with most chemicals. This keeps experiments pure. It is good for catalyst testing or calcining powders.

Its stamina is vital. Alumina ceramic is very hard. It endures misuse and repeated heating cycles. This makes it last longer than cheaper products. The high pureness alumina uses exceptional thermal security. It will not plunge or warp at working temperature levels. Users conserve cash in time. They require less substitutes. It gives dependable protection for useful materials.

5 FAQs of High Temperature of The Sagger Box Rectangle Alumina Crucible Ceramic Refractory Crucible Boat

What temperature can this crucible handle?
It withstands up to 1800°C (3272°F). This is its maximum safe working temperature for long periods. Don’t exceed this limit. The crucible will fail.

How fast can I heat it up?
Heat it slowly. Avoid sudden jumps in temperature. Increase the heat gradually. This prevents cracking from thermal stress. Follow your kiln’s recommended ramp rates.

Can it handle quick temperature changes?
It resists thermal shock better than many materials. Avoid drastic temperature swings. Sudden cooling is especially risky. Let it cool down slowly inside the kiln. This is safest.

How long does it last?
Lifespan varies. It depends on temperature, cycling frequency, and the materials melted. Used correctly, it lasts for many firings. Avoid mechanical damage and thermal shock. This extends its life.

How do I clean it?
Remove residues after each use. Let it cool completely first. Use mechanical methods like gentle scraping. Avoid harsh chemicals. They might damage the alumina surface. Check for cracks before reusing it.
