Specification of Alumina Ceramic Fiber Crucible with Lid

This alumina ceramic fiber crucible offers a practical solution for high-temperature tasks. It is made primarily from alumina ceramic fiber material. This material gives the crucible excellent heat resistance. It handles temperatures up to 1500°C (2732°F) easily. This makes it suitable for melting various materials. Common sizes range from small 50ml capacities to larger 500ml options. You find them in different shapes. Cylindrical and conical shapes are typical. The crucible comes with a matching lid. The lid fits snugly. It helps contain materials inside during heating. It prevents spills. It reduces heat loss significantly. The lid is also made from alumina ceramic fiber. It withstands the same high temperatures as the crucible body.

The crucible itself is very lightweight. This makes handling it straightforward. Its structure is porous. This porosity provides good insulation properties. It heats up quickly. It cools down rapidly too. This characteristic offers good thermal shock resistance. The crucible won’t crack easily under sudden temperature shifts. It maintains its shape well under heat stress. Alumina ceramic fiber is chemically stable. It resists attack from many fluxes and molten metals. This ensures a longer service life. It minimizes contamination of your samples or melts. You can use this crucible repeatedly.

People use these crucibles in laboratories and small-scale foundries. They are common for melting precious metals like gold or silver. They work well for melting alloys. They are useful for ash testing procedures. The combination of high temperature tolerance and thermal shock resistance is key. The fitted lid adds extra value for containment. This crucible provides reliable performance for demanding thermal applications.

5 FAQs of Alumina Ceramic Fiber Crucible with Lid

What is an alumina ceramic fiber crucible with lid made from?
This crucible uses alumina ceramic fibers. These fibers are spun together. The result is a lightweight material. It handles very high heat well. The lid matches the crucible material. It fits snugly.

How much heat can this crucible take?
It withstands temperatures up to 1600°C (2912°F). That is its maximum limit. Do not exceed this. It handles rapid heating well. Avoid sudden temperature drops. Cooling too fast can damage it. It works best above 1000°C for long periods.

Can it handle strong chemicals?
Yes, it resists many chemicals well. It handles acids and bases okay. It is good against molten salts. Avoid strong alkalis like potassium hydroxide. Avoid hydrofluoric acid too. These can damage the fibers. Check chemical compatibility before use.

Why use the lid?
The lid is important. It keeps heat inside the crucible. This helps reach uniform temperatures faster. It protects your sample from drafts. It prevents dust and debris from falling in. It reduces material loss from splashing. Always use the lid for best results.

Can I reuse this crucible?
Yes, you can reuse it many times. It depends on how you use it. Check for cracks after each use. Look for chips or severe wear. Avoid sudden temperature shocks. Handle it gently. It lasts longer than some other ceramic types. Replace it when it shows damage.
