QUARTZ GLASS CRUCIBLE AND METHOD FOR TREATING SURFACE OF QUARTZ GLASS CRUCIBLE |
摘要 |
There is provided a quartz glass article having a surface treated with novel coating materials which provides a reduced chemistry, wherein the quartz glass surface having a reduced chemistry upon exposure to melted silicon or similarly corrosive environments, forms crystalline structures covering at least 30% of the coated surface of the quartz glass crucible. Said crystalline covered surface provides a more stable surface of contact with the silicon melt and the growth of single crystal silicon. In one embodiment of the invention, the coating material comprises at least a methyl group for providing at least one of a hydrogenated and a methylated surface on the coated surface, forming rosette structures, or other crystalline morphologies covering at last 80% of the coated surface. In another embodiment of the invention, the coating material is selected from at least one of an amine, an organosilane halogen and mixtures thereof. |
