The low-cost alternative to platinum virtually eliminates sample contamination.

The advantage of using zirconium crucible is that they do not require platinum head pliers.

Zirconium crucible is fragile! Handle with care during unpacking, transportation, handling and cleaning.

Zirconium exhibits excellent corrosion resistance in most organic and inorganic acids, salt solutions, strong alkalis and a few molten salts. An effective all-purpose crucible suitable for melting using sodium carbonate and sodium peroxide.

Heating zirconium produces a milky white passivated oxide film that is resistant to corrosion and stable under both reduction and oxidation conditions. Check for any microcracks before heating any crucible and replace with a new zirconium crucible.

Do not overload the material in the zirconium crucible, which increases the possibility of uneven heating.

Argon or helium zirconium crucible can be heated to 1450°C under vacuum, otherwise the temperature limit for use in air is 450°C to 500°C.

A slow rate of heating and cooling is strongly recommended to minimize thermal shock on the crucible. When increasing the temperature, special attention should be paid to the two sensitive temperature periods: no more than 1200°C/MIN during 3°C ~100°C and 300°C ~1050°C. Rates can be faster in other temperature ranges, but less than 5°C /MIN is recommended.

Do not remove zirconium crucbles directly from the furnace at high temperatures, or they may crack. It is recommended to remove from the heat when the temperature is below 100°C,

Zirconium crucibles should not be heated by torches or furnaces that cannot control the rate of temperature change. Uneven heating can lead to cracks!
