Semiconductor quartz crucible

Disposable, high-purity containers used to manufacture monocrystalline silicon ingots—the foundational material for chips—represent the "first critical checkpoint" determining chip quality. Extreme purity: The inner layer must achieve a purity of 99.998% or higher to prevent impurities from contaminating the silicon crystal. Thermal stability: They must resist deformation and cracking during prolonged exposure to high temperatures, ensuring the continuity of the crystal-pulling process.
