Crystal Growth Crucible Holder from United States
A crystal growth crucible holder is a high-temperature-resistant holder designed to secure quartz crucibles in Czochralski silicon crystal pullers. It maintains crucible alignment and temperature stability during the crystal growth process, which is essential for producing semiconductor-grade silicon. This holder is equally suitable for use with machines of headings 84.70 to 84.72, as it supports the preparation of components for ADP systems.
