Silicon Crystal Ingot Processing - Silfex
High-purity, semiconductor-grade silicon (only a few parts per million of impurities) is melted in a crucible at 1,425 °C (2,597 °F; 1,698 K), usually made of quartz. Dopant impurity atoms such as boron or phosphorus can be added to the molten silicon in precise amounts to dope the silicon, thus changing it into p-type or n-type silicon, with different electronic properties. A precisely oriented rod-mounted seed crystal is dipped into the molten silicon. The seed crystal's rod is slowly pulled up… WebThe wide variety of crystal ingot available allows you greater freedom in selecting your choice of art, from crystal beads for jewelry making to crystal art diamond painting.
