Product Description
Excellent low cost replacement to platinum virtually eliminates sample contamination.
Benefit of using zirconium crucibles, they do not require platinum tipped tongs.
Zirconium crucibles are fragile! Handle carefully during unpacking, transportation, handling and cleaning.
Zirconium exhibits superb corrosion resistance in most organic and inorganic acids, salt solutions, strong alkalis and a few molten salts. An effective all round crucible for fusions employing sodium carbonate and sodium peroxide.
Heating zirconium produces a creamy white passive oxide film, corrosion barrier, stable in both reducing and oxidizing conditions. Check before heating any crucible for any micro-cracks, replace with new zirconium crucible.
Do not over load material in zirconium crucibles, this can increase the possibility of uneven heating.
Under vacuum, argon or helium zirconium crucibles can be heated to 1450°C otherwise temperature limit for use in air is 450˚C to 500˚C.
A slow heating ramp rate and cooling rate are highly recommended to minimize the thermal shock on crucibles. When increasing the temperature, special attention should be paid on two sensitive temperature periods: not exceeding 3°C/MIN during 100°C ~300°C and 1050°C ~1200°C. The rate can be faster in other temperature ranges, but it is recommended to be less than 5°C /MIN.
DO NOT take zirconium crucibles directly out of furnace at high temperature otherwise they may crack. Recommend remove from heat when the temperature is under 100°C.
Zirconium crucibles should NOT be heated by torch or furnaces that cannot control temperature change rate. The uneven heating can cause cracks!
