5ml 702 Zirconium Crucible Laboratory

5ml 702 zirconium crucible product instructions

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

Heating zirconium produces a milky white passive oxide film, a corrosion barrier that is stable under both reducing and oxidizing conditions. Check for micro-cracks before heating the crucible and replace with a new zirconium crucible.

Do not over load the zirconium crucible with material, this increases the likelihood of uneven heating.

Argon or helium zirconium crucibles can be heated to 1450°C under vacuum, otherwise use in air is limited to 450°C to 500°C.

It is strongly recommended to use slow heating and cooling rates to minimize thermal shock on the crucible. When heating up, special attention should be paid to two sensitive temperature ranges: 100°C~300°C and 1050°C~1200°C period not exceeding 3°C/MIN. The rate may be faster in other temperature ranges, but less than 5°C/MIN is recommended.

Do not take the zirconium crucible directly out of the furnace at high temperatures or it may break. It is recommended to remove from heat source 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 cause cracks!
