Zircon - crucible

Zirconium crucibles (zirconium metal/zirconium oxide) are primarily used for melting, crystal growth, and reaction vessels in high-temperature, high-purity, and highly corrosive environments. With their four major advantages—high melting point (1852℃), chemical inertness, corrosion resistance, and thermal shock resistance—they are irreplaceable in semiconductors, metallurgy, photovoltaics, scientific research, and the nuclear industry.

I. Semiconductors and Electronics (Core Applications)
Single-crystal silicon/compound semiconductor crystal growth: Czochralski (CZ) method for growing single-crystal silicon, GaAs, SiC, sapphire, and YAG laser crystals, eliminating metal ion contamination and ensuring wafer/crystal purity and uniformity.

Chip manufacturing: High-purity reaction/supporting containers for high-temperature diffusion, ion implantation, and CVD/PVD thin film deposition.

Optical glass/specialty glass melting: Preparation of high-transmittance, low-impurity optical glass.

II. High-Temperature Metallurgy and Rare Metals
Vacuum melting of reactive/refractory metals: High-purity melting of titanium, zirconium, hafnium, tantalum, niobium, tungsten, molybdenum, etc., without reacting with the molten metal, ensuring precise composition. High-Temperature Alloy/Special Alloy Casting: Smelting and forming of high-temperature alloys and corrosion-resistant alloys for aero-engines.

Rare Earth/Permanent Magnet Material Preparation: Sintering and smelting of rare earth permanent magnets such as NdFeB, reducing impurities and improving magnetic properties.

Precious Metal Refining: Purification and melting of precious metals such as platinum, palladium, gold, and silver.

III. Photovoltaic Industry
Silicon Smelting/Polycrystalline Silicon Ingot Casting: Melting of photovoltaic-grade silicon and casting of polycrystalline silicon ingots, suitable for large-size silicon wafer production.

Perovskite Cell R&D: High-temperature synthesis and sintering of new photovoltaic materials.

IV. Chemical and Special Materials
High-Temperature Reactions in Strongly Corrosive Media: Reaction vessels for harsh systems such as concentrated acids, concentrated alkalis, and molten salts.

High-Performance Ceramics/Composite Material Sintering: High-temperature sintering and forming of ceramics such as zirconium oxide, silicon nitride, and silicon carbide.

V. Scientific Research and Laboratories
High-purity material synthesis/thermal analysis: Differential thermal analysis (DTA), thermogravimetric analysis (TG), high-temperature solid-state reaction, standard containers for zone melting purification.

High-temperature treatment of special samples: High-temperature annealing and sintering of contamination-sensitive metal, ceramic, and semiconductor samples.

VI. Aerospace and Nuclear Industry
Aerospace: Smelting of high-temperature alloy components, preparation of rocket nozzles/reentry protection materials.

Nuclear Industry: Pretreatment of nuclear-grade zirconium materials, sintering and purification of nuclear fuel, separation of radioactive isotopes (low neutron absorption cross-section).

VII. Other Industrial Scenarios
Specialty Glass/Enamel: Smelting and forming of acid- and alkali-resistant glass and high-temperature enamel.

Electrolytic refining: Electrolytic purification of high-purity aluminum, copper, and other non-ferrous metals.
