Much of the bulk crystal growth begins with sealing source powders in quartz ampoules for later processing. Here are videos detailing how we prepare our quartz ampoules.
Cutting Quartz Tubing with a Tube Cutter
This video details how 2DCC personnel cut quartz tubing into desired tube lengths for later ampoule preparation.
Creating One-End Closed Quartz Tubes
This video highlights how we use an oxygen-hydrogen torch to split quartz tube to make one-end closed (test tube) quartz tubes.
Sealing Non-Oxygen Sensitive Ampoules
In this video, we show how we seal our ampoules that contain source material that is not sensitive to exposure to air.
