A quartz crucible is a container or furnace made of refractory materials. Below, we will learn about the reasons for sandblasting on quartz crucibles:
A quartz crucible is a ceramic bowl shaped container with a deep bottom. When there is a solid that needs to be heated over high heat, a quartz crucible should be used. Because it can withstand higher temperatures than glassware, the lid is usually placed tilted on a quartz crucible to prevent the heated material from escaping and allow air to freely enter and exit for possible oxidation reactions.
Due to the very small bottom of the quartz crucible, it usually needs to be installed on a mud triangle before it can be directly heated with fire. It can be placed upright, tilted on an iron tripod, or placed on its own according to experimental needs. After heating, the quartz crucible should not be immediately placed on a cold metal table to avoid cracking due to rapid cooling. They should not be immediately placed on wooden tabletops to avoid burning the tabletop or causing a fire. The correct approach is to naturally cool it on an iron tripod or slowly cool it on an asbestos mesh.
That's all for the brief introduction of the reason for product sandblasting. If you have any questions in the future, please feel free to consult us.
