W crucible with lid
Tungsten crucible (round, square, rectangular, tapered shapes) is widely used in technologies for growing monocrystals from molten corundum, it is also used in electronics and technologies for thermal vaporization – deposition of various substances. It is an important part of a high-temperature furnace cause of its high melting point.
Tungsten metal is resistant to certain molten metals and metal oxides, and it has high-temperature resistance and low pollution. W crucible and other pure W & molybdenum parts can be used for sapphire crystal growth and rare-earth melting due to their and other excellent characteristics.
Non-Ferrous Crucible Inc. supplies all kinds of Tungsten crucibles (crucible body and lid, round crucible, tapered crucible, customized square & rectangular crucible) and pure tungsten parts (heaters, heat insulation screens, sheets, and supports, etc.), which are used in the process of sapphire growth and rare-earth melting.

Applications of Tungsten Crucibles
-Semiconductor Manufacturing: Used to melt and hold high-purity materials such as silicon, gallium arsenide, and germanium during the crystal growth process in semiconductor manufacturing.
-Metallurgy: Used to produce high-temperature alloys and metals such as titanium, steel, and superalloys, where tungsten crucibles provide a stable and inert environment for melting and casting processes.
-Chemical Processing: Due to its corrosion and high-temperature resistance, tungsten can be used to contain and heat highly corrosive chemicals and molten salts in chemical synthesis, refining, and purification processes.
-Glass Manufacturing: Used to produce specialty glass and optical fibers, where tungsten crucibles provide a stable and contamination-free environment for melting and forming glass materials.
-Thin Film Deposition: Used in physical vapor deposition (PVD) and chemical vapor deposition (CVD) processes to produce thin films and coatings on substrates in the semiconductor, optical, and aerospace industries.
Tungsten Rectangular Crucible
-Laboratory Research: Used in laboratory environments for high-temperature experiments, material synthesis, and chemical reactions that require an inert and stable container.
Packaging for our tungsten
Tungsten crucibles and other tungsten products are fragile and heavy, careful handling is needed. The standard package for tungsten products is a wooden crate so that the product can be protected during handling and transportation. Carton is also used for small crucible sets.
