Example Embodiment
[0033] Example 1
[0034] Clamp the loose powder rod 7 at the lower end of the quartz push rod 2, and send the loose powder rod 7 into the upper part of the sintering furnace core tube 6 through the rod feeding device 1. After the loose powder rod 7 is in place, the cover plate 3 on the top of the furnace core tube 6 is sintered Also cover at the same time; use the induction heating furnace 8 to increase the temperature in the furnace core tube to 1000 ℃, and pass a specified amount of process gas such as chlorine, helium, etc. into the furnace core tube through the air inlet 12. The chlorine flow rate is 0.05 slm, helium The air flow rate is 5slm, and the rod feeding device 1 is turned on to feed the loose powder rod 7 downwards at a speed of 10mm / min, and rotate through the hot zone of the heating furnace 8 at a speed of 1rpm. When the dehydration process of the entire loose powder rod 7 is completed, The rod body stops at the position where the dehydration is finished (at this...

[0037] Example 3
[0038] Clamp the loose powder rod 7 at the lower end of the quartz push rod 2, and send the loose powder rod 7 into the upper part of the sintering furnace core tube 6 through the rod feeding device 1. After the loose powder rod 7 is in place, the cover plate on the top of the sintering furnace core tube 6 is also Cover at the same time; use the induction heating furnace 8 to increase the temperature in the furnace core tube to 1300 ℃, and pass a specified amount of process gas such as chlorine, helium, etc. into the furnace core tube 6 through the air inlet 12. The chlorine flow rate is 2 slm, The flow rate of helium gas is 20slm, and the rod feeding device 1 is turned on to feed the loose powder rod 7 downwards at a speed of 20 mm / min, and rotate through the hot zone of the heating furnace at a speed of 5 rpm. When the dehydration process of the entire loose powder rod 7 is completed, The rod body stops at the position where the dehydration ends (at this time...
