Molded Crucibles


Molded CruciblesTypically available in Pyro220. Other materials available by special request. High purity fused quartz Pyro220 crucibles are made in a broad range of sizes for the Czochralski process of growing single crystal silicon ingots.

They are formed using a proprietary process involving strictly controlled atmosphere and thermal gradients.  Subsequently, they have a number of advantages over crucibles formed by the conventional method of arc fusing quartz sand.  Pyro220 crucibles are characterized by their transparency, high temperature strength, dimensional precision and low bubble content. These properties have been proven to promote superior crystal yields in the semiconductor industry.

Pyro220 crucibles transfer more radiant heat than opaque crucibles, which reduces the amount of sweeping gas required and results in better temperature control.  Due to its distortion resistance in high temperatures, the crucible helps to extend the life of the graphite susceptor.  Pyromatics’ crucibles have excellent dimensional precision along their bottom radii, walls, and diameters, insuring a good fit in the susceptor.  The smooth exterior finish allows the crucible to be placed in the susceptor without abrasion, keeping the furnace free of loose graphite particles.
