top grade graphite crucible

The main raw material of graphite crucibles is crystalline natural graphite, which has excellent thermal conductivity and high-temperature resistance, strong corrosiveness to acid and alkali solutions, and good chemical stability. There are various types of graphite crucibles, but their application scope is relatively narrow, allowing for free selection. Based on the above excellent properties, graphite crucibles are widely used in industrial fields such as metallurgy, casting, machinery, and chemistry, and can also be used for the refining and refining of non-ferrous metals and new materials.     There are some instructions for use. As the bottom of the crucible is very small, when heating, the crucible needs to be placed on a graphite pad or a clay triangle. Direct heating is possible, but immediate cooling after heating is impossible. Take it out with tongs. Do not place it on a cold metal table to avoid cracking due to rapid cooling. During use, it is essential to check for any ob…
