•Re-usable for several crystallization firings
•Material classified as Advanced Ceramics (<100 MPa)
During the furnace process, the silica crucible is transformed from a glassy to a crystalline phase. During cooling, the crystalline SiO2 undergoes a phase transition that causes breakage. For this reason, the silica crucibles may only be used once. This gives a significant contribution to the production costs of the ingots.
With Steuler Solar crucibles of high performance silicon nitride, the crucible is practically chemical inert and the physical properties will contribute to long lifetime that can withstand several runs of silicon crystallizations.
