Advanced Refractory Metals (ARM) offers high-purity zirconium crucibles with excellent corrosion resistance, thermal stability, and chemical inertness. Ideal for crystal growth, metal processing, and nuclear applications, these crucibles perform reliably under extreme conditions.
Zirconium crucibles are made from high-purity zirconium and built to handle extreme heat and chemicals. With a melting point of 1,855 °C and strong corrosion resistance, they’re perfect for crystal growth, nuclear work, and handling reactive metals. They're also great in vacuum or inert gas setups thanks to their low neutron absorption. Each crucible is precisely made for a smooth finish and tight fit, with standard and custom sizes available.
Advanced Refractory Metals supplies various kinds of zirconium crucible. Customization is available by your request.

Crystal Growth: Used in the synthesis of optical and semiconductor crystals (e.g., YAG, sapphire) via methods like Czochralski or Bridgman.
High-Temperature Metallurgy: Ideal for melting and processing reactive or high-purity metals.
Nuclear Industry: Suitable for fuel material processing due to zirconium’s low neutron absorption.
Chemical Processing: Handles corrosive acids and alkalis in aggressive environments.
Laboratory Use: Employed in thermal analysis, TGA/DSC experiments, and material synthesis under controlled atmospheres.
Multiple sizes are available and we do make customized products.
Our Zirconium crucibles are carefully handled to prevent damage during storage and transportation and to preserve the quality of our products in their original condition.
