This article mainly describes the advantages and applications of different materials crucible. 1. Tungsten boat: · High temperature resistance: Tungsten boat has excellent high temperature resistance and can withstand the vacuum evaporation process at high temperature. · Thermal conductivity: Tungsten has good thermal conductivity and can provide uniform heating, which helps to obtain uniform film deposition. Stability: tungsten is relatively stable at high temperature, not easy to oxidize, suitable for evaporation under high temperature conditions.     2. Boron nitride crucible: · Adhesion resistance: boron nitride crucible has good adhesion resistance, which can reduce material residue and pollution. · Electrical conductivity:  boron nitride(BN)  crucibles usually have low electrical conductivity, which is helpful for certain processes where electronic conduction needs to be controlled. · Chemical inertia: boron nitride crucible is relatively inert in many chemical...

For these researchers, our most suitable and standard product is ceramic crucible. This word may be new to the general public. Still, crucibles are good friends of the lab and a loyal helper of researchers to do experiments. Clays originally made crucibles, and one of the earliest uses of platinum was also making crucibles. However, with the development of preparation technology, crucibles can now be composed of any material that can melt or change its contents. Image by Skieze from Pixabay What is a crucible? Crucibles are vessels made of extremely refractory materials such as clay, graphite, porcelain... Its role is to melt and refine metallic liquids, and also as a solid-liquid heating and reaction vessel. Crucibles belong to chemical instruments. When we heat solid by fire, we must ...
