    White Refractory Ceramic Crucibles Graphite Melting Crucible For Drying Burning


    Crucibles (ceramic crucibles, graphite crucibles, refractory crucibles)


    Ceramic Crucibles, Graphite Crucibles, Refractory Crucibles,For Drying, Burning, Melting Or Heating


    We offer a range of crucibles suitable for calcinating and melting various alloys.The main quality of a crucible is its ability to withstand temperatures above the melting temperatures of the alloys deposited by metallurgists without altering or polluting the molten metal. In some cases, when a crucible is brought to these very high temperatures, it must be strong enough to withstand being moved for the casting of parts (bronze foundry for example).

    Crucibles (ceramic crucibles, graphite crucibles, refractory crucibles) are containers for drying, burning, melting or heating various substances for use in metallurgy, glass industry, growing crystals, laboratory equipment, various high-temperature equipment.


    Our team is available to help you choose the crucible and the material that best meet your requirements.
