ition in our production work. It is made of quartz as the basic material. If you want to use it for a longer period of time, you may wish to try it according to the following methods:

Milky white quartz tube

The temperature resistance of the quartz tube is related to its purity. The higher the purity, the higher the temperature resistance, but the softening point of the quartz tube is 1270 degrees, and it should not exceed 3 hours when used at 1200 degrees. Quartz glass that requires high temperature must be wiped clean before use. Can be soaked with 10% hydrofluoric acid or lotion, and then washed with high-purity water or treated with alcohol.

Wear thin-line gloves during operation, and do not allow direct contact with quartz glass by hand. Keep the furnace tube clean and hygienic, and no material that reacts with SiO2 can remain in the furnace tube. When burning the material, in order to make the furnace tube have a longer service life, do not put the material directly on the furnace tube and use a boat-shaped crucible. Quartz glass products are valuable materials, and they must be handled with care when used.
