Grafietsmeltkroes kenmerken en toepassing

A graphite crucible is a container made of a graphite material, commonly used in high-temperature experiments, chemical analysis and metal smelting, en andere velden. It has many excellent characteristics that make it ideal for handling high-temperature substances and corrosive solutions.

The use of a graphite crucible

Graphite crucibles can withstand high temperatures, so graphite crucibles are mainly used for melting precious metals, alloys, en andere metalen materialen, and can also be used in experiments to heat various chemical substances.

Features of graphite smelting crucible

Graphite smelting crucible has good thermal conductivity and high-temperature resistance. During high-temperature use, its thermal expansion coefficient is small, and it has certain strain resistance to rapid heating and rapid cooling. It has strong acid and alkaline solution corrosion resistance and good chemical stability.

How to maintain the service life of a graphite crucible？

1. Avoid sudden temperature changes: rapid temperature changes can cause thermal stress on the graphite crucible, which can damage the crucible structure. During the heating or cooling process, sharp temperature changes should be avoided as far as possible, and the method of gradual heating or cooling can be adopted.
2. Cleaning and maintenance: After using the crucible, its surface should be cleaned in time to remove residues. You can use a soft brush or cotton cloth to wipe gently and avoid using hard objects or rough cleaning tools, so as not to scratch the surface of the crucible. For more stubborn residues, mild detergents can be used, but avoid strong acid or alkaline solutions.
3. Avoid violent shocks: Graphite smelting crucibles should be protected from severe shocks or collisions to avoid breakage or cracks. Handle with care when handling and storing, and avoid contact with hard objects.
4. Proper storage: When the graphite smelting crucible is not in use, it should be properly stored in a dry and clean place, avoiding contact with environments with high humidity or corrosive gases. It can be wrapped in a plastic bag or closed container to prevent the accumulation of dust and impurities.
