Specifications of Alumina Ceramic Fiber Crucible with Lid

This alumina ceramic fiber crucible handles high heat well. It comes with a lid. The crucible is made mostly from alumina ceramic fiber. This material is good for very hot environments. It works fine up to about 1650 degrees Celsius. The crucible also handles fast temperature changes without breaking. It does not crack easily under heat stress.

Several sizes are available. Common sizes include 10 ml, 25 ml, 50 ml, 100 ml, and 250 ml capacities. The crucible feels lightweight. Its density is low. This low density helps with heat insulation. It keeps heat inside effectively. The material is porous. This porosity helps it resist thermal shock.

The alumina ceramic fiber resists chemical attack. It works well with many chemicals. It handles acids and bases without damage. The crucible is strong. It lasts a long time even with frequent use. The crucible surface is smooth. This smoothness helps prevent sticking.

The matching lid fits tightly. This tight seal protects the contents. It keeps things clean inside. The lid is also made from the same alumina ceramic fiber. It withstands the same high temperatures. The lid helps control the heating process.

Applications of Alumina Ceramic Fiber Crucible with Lid

Alumina ceramic fiber crucibles with lids are special containers. They are made from a unique material. This material handles very high heat well. It also resists sudden temperature changes. This is important in many tough jobs. These crucibles are strong. They do not break easily under stress. They are also very light. This makes them easy to move around. The lid fits tightly. It keeps things inside safe and contained.

People use these crucibles in science labs. They are good for melting small amounts of metal. They are also used for testing new materials. The crucible holds the material while it gets very hot. This helps scientists see how it changes. The crucible works well with different heating methods. People use them in electric furnaces. They also use them with gas burners. The crucible stays stable. It does not crack or fall apart.

These crucibles are common in research. They help develop new alloys. They are also used for checking how pure a material is. The high heat lets impurities burn away. The lid stops stuff from flying out. This keeps the experiment clean. The crucible lasts a long time. It does not wear out quickly like some other types. This saves money. You don’t need to buy new ones often. They are a good choice for high heat work.

5 FAQs of Alumina Ceramic Fiber Crucible with Lid

Alumina ceramic fiber crucibles with lids handle high heat well. They work in labs and industry. People often ask questions about them.

What’s the highest temperature these crucibles reach? They handle up to 1600°C or 2912°F. This suits melting metals like gold or silver. Keep within this limit. Going over risks damage.

How long will one crucible last? It depends on use. Frequent high heat cycles shorten its life. Proper care helps it last longer. Avoid sudden temperature changes. Handle it gently to prevent cracks.

Can I use this crucible with any chemical? No, check chemical compatibility first. Alumina resists many things. But strong acids or alkalis might attack it. Know what materials you melt. Avoid incompatible substances.

Is the crucible fragile? Yes, handle it carefully. The ceramic fiber material is somewhat brittle. Don’t drop it or hit it hard. Thermal shock from fast heating or cooling can cause cracks. Heat and cool it slowly.

Do I really need the lid? Yes, the lid is important. It helps control the temperature inside better. It keeps heat in for melting. It also stops dust or other things falling into your melt. Always use the lid when melting.
