Application Tips of the Quartz Tube During the Use of Microwave Tube Furnace


Due to its unique structure, the tube is an important and key part of the microwave tube furnace, and it is also the reaction

place and working area during the production test. And the tube is directly related to the gas, pressure and operation

method. Therefore, pay attention to the use and maintenance of the quartz tube during the use of the microwave tube furnace:

1) Softening Point: 1683°c Annealing Point: 1215°c Strain Point: 1120°c. Do not use it for more than 3 hours at 1200°c.

2) In general, microwave tube furnace is not recommended for customers to import hydrogen. Hydrogen content

should control under 15%!

3). Keep the inside tube clean and sanitary, the materials that react with SiO2 must not remain in the tube. In order

to make the tube a longer service life, do not put the material directly on the tube and hold it in a boat.

4). Be sure to put ceramic plugs in the tube when heating, which improve the thermal uniformity inside the tube.

5) The temperature resistance of quartz tube is related to its purity. The higher the purity, the higher the temperature
