فرن أنبوبي عمودي صغير عالي الحرارة في المختبر

TFV-1200-50-I-220 is a small open type vertical tube furnace with a tube diameter of φ 30/50 mm. It is applicable to sintering and quenching of samples in vacuum or atmosphere. With different accessories and installations, it can also be used as a fluidized bed vertical tube furnace for CVD experiment on powder surface deposition. In this case, a quartz sand core with a diameter of 5-15 um is embedded within the high purity quartz tube. The sintered powder is placed on the sand core layer. Deposition experiment shall be carried out by passing the gas to the sand core layer through the flanges at the bottom of the tube and keeping the sample particles suspended in the heating zone under the effect of the gas flow (generally stabilized in the constant temperature zone).
