Characteristics and Application of Graphite Crucible
Graphite crucible – this is a container, made of graphite material, commonly used in high temperature experiments, chemical analysis and smelting of metals, as well as in other areas. It has many excellent characteristics, which make it ideal for working with high-temperature substances and aggressive solutions.
Using Graphite Crucible
Graphite crucibles withstand high temperatures, Therefore, graphite crucibles are mainly used for melting precious metals, alloys and other metal materials, and can also be used in experiments on heating various chemicals.
Features of Graphite Melting 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 extend the service life of graphite crucible？
- Avoid sudden changes in temperature: sudden changes in temperature can cause thermal stress on the graphite crucible, which can damage the crucible structure. During the heating or cooling process, sudden changes in temperature should be avoided if possible and a gradual heating or cooling method can be used.
- Cleaning and care: After using the crucible, its surface should be promptly cleaned of residues.. For gentle wiping, you can use a soft brush or cotton cloth and avoid using hard objects or harsh cleaning agents., to avoid scratching the surface of the crucible. Mild detergents can be used to remove more stubborn residues, but avoid strong acidic or alkaline solutions.
- Avoid strong impacts: Graphite melting crucibles should be protected from strong impacts or collisions, to avoid breakage or cracks. Use caution during handling and storage and avoid contact with hard objects.
- Proper storage: When the graphite melting crucible is not used, 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 dirt.
