Quartz Crucibles

Trusted. Versatile. Superior.

In the manufacture of silicon wafers for semiconductor applications, polysilicon starting materials are placed in a fused quartz crucible, heated to high temperatures and pulled from the melt as a single crystal. Fused quartz is the oxide of the silicon molten in it, minimizing contamination concerns, and one of the few materials that can combine the high purity and high temperature properties required.

Key Features

  • Customizable by dimension, purity, bubble content and coating to meet specific customer needs
  • Regional sales offices worldwide ensure responsive and attentive local support
  • Available from 14 to 36 inches in diameter to accommodate a wide range of hot zone designs

Potential Applications

  • Semiconductor silicon ingot growth
  • Semiconductor equipment parts
  • Firing of various materials
  • Belljar
