Quartz Tubes in CVD Tube Furnaces: Sealing, Flow, Safety

This page explains how quartz tubes actually function inside a CVD tube furnace, and why their interaction with the flange system directly affects sealing, gas flow stability, process repeatability, and safety.
If you use a CVD furnace and want to understand where performance issues really come from, this article connects the quartz tube itself with the practical role of the flanges around it.
