Point Bottom Alumina Crucible


Advantages

1. Point bottom alumina crucible has a high temperature resistance of up to 1800°C.

2. It has excellent thermal shock resistance and can withstand sudden temperature changes.

3. It has a low thermal expansion rate, which ensures that the crucible maintains its shape and size even at high temperatures.

4. It has a high chemical resistance and is resistant to most acids and alkalis.



Description

1. Point bottom alumina crucible is made of high-grade alumina material.

2. It is ideal for use in laboratory and industrial applications.
3. The melting pot has a direct penetrate design, which allows for easy pouring of molten materials.
4. The melting pot is highly serviceable and can be old multiple times without any damage.
5. The crucible is likewise resistant to chemical substance corrosion and is soft to clean.
