Can the graphite crucible be rinsed with water?
It is not recommended to wash with water. If you rinse with water or get wet, you must bake for about 20 hours before use, until it is completely dry. Otherwise, the graphite crucible will burst because of heating. The graphite crucible has good thermal conductivity and high temperature resistance, and the thermal expansion coefficient is small in the process of high temperature use, and has a certain anti strain property for hot and cold quenching. The corrosion resistance of acid and alkaline solution is strong, and it has good chemical stability. In metallurgy, casting, machinery, chemical and other industrial sectors, it is widely used in smelting of alloy tool steel and smelting of nonferrous metals and their alloys. And has better technical and economic results.
When the graphite crucible is heated, it will burst. If you rinse it with water, you must bake for about 20 hours before you use it. When the pan is completely dry, it's best to bake about six Baidu at regular intervals.
According to the remnants of the graphite crucible is what determines what to clean, general graphite crucible attachment on the residue after combustion of inorganic, can use hydrochloric acid to clean up, most of them can be dissolved, some contains carbon residue, acid insoluble salt is used, then you can use nitric acid cleaning, because nitrate has strong oxidation, cleaning can be properly heated.
Graphite crucibles can be rinsed with water. The graphite crucible will burst when heated.
