Many experiments in chemical experiments also require heating. There are many heaters that we use. Among them, the most widely used ones are the ones.
Crucibles, can be used for the intensity heating of a large number of crystals, and can be divided into graphite crucibles and quartz crucibles. Graphite crucible has good thermal conductivity and high temperature resistance; in high temperature use, the coefficient of thermal expansion is small, it has strong resistance to extreme heat and extreme cold, and it is resistant to strong acid and alkali, and can be applied to heating of various liquids; Graphite crucible has a wide range of uses in metallurgy, foundry, machinery, chemical and other departments; graphite crucible is made of natural graphite raw materials, which maintains the original excellent characteristics of graphite.
Graphite crucibles for fire-fighting heating are mainly used for the melting of non-ferrous metals such as copper, aluminum, and alloys. There are so many features of graphite crucible itself.
Due to the reasonable design, advanced structure and novel materials, the energy consumption of the graphite crucible is lower than that of the same type of furnace.
Clean energy such as natural gas or liquefied gas can be used as fuel and less pollution.
Resistance furnace high-purity graphite crucible is mainly used for the melting of gold, silver and rare metals. Ceramic crucibles are mainly used in the laboratory and in the melting of platinum, gold and rare metals. Can graphite crucible work under air conditions at 2000 °C, will it decompose oxidatively? Will it make the molten metal carburize? The most important thing is that carburization is fatal. Under normal circumstances, it can reach 2000 degrees in the air, but it will oxidize rapidly, and the problem of metal carburization must exist.
