摘要: The purpose of this research is designed and constructed a small vacuum furnace. A cylindrical graphite was chosen as the material furnace, cylinder aluminium copper sheets were employed to prevent heat radiation that transfers from furnace chamber wall. rotary pump used, pressure can be pumped up 30 mTorr heated 700 °C driving by wire temperature wall relatively remained too low. In addition, loss obtained conduction, convection, analyzed. dominating found caused blackbody radiation, which thus used estimate relationship between drive power needed. has an inner diameter 44 mm, outer 60 mm 45 in height, 355.5 W needed °C.
