Zirconium Crucible Zirconium Cups

Features and Benefits :Why Zirconium crucibles?
It is no secret that zirconium crucibles cost more than porcelain, steel or nickel. However the average number of fusions that can be made in a zirconium crucible, as opposed to those of nickel, the ratio of longevity stands at 20 to 1. The higher cost zirconium crucible is recovered many times over.In addition to cost effectiveness, zirconium crucibles hold several advantages over other materials in the laboratory. If compared to platinum, several distinct advantages are readily apparent.- Ideal for most fusions done in full heat, resulting in little or no attack or oxidationof the crucible regardless material or flux mixture.- Resistant to melts of alkali (Na, K, Li) carbonates, hydroxides, peroxides, borates, nitrates, chlorides and some fluorides, or combinations of above.- Completely resistant to most solvents of all concentrations except hydrofluoric acid.- Offers virtual elimination of sample contamination.- Resistance to molten sodium peroxide.- Will not alloy with more easily reducible metals.- Unlike platinum no smoothing and reshaping is necessary.- Does not have the high-cost investment and security problems of platinum.
