发明名称 Membrane for capacitive vacuum measuring cell
摘要 A ceramic membrane for a capacitive vacuum measuring cell includes a thin ceramic membrane with a thickness of <250 mum, in particular less than 120 mum. The membrane is produced from a ribbon-shaped green body of Al2O3, and is given high planarity by smoothing the membrane after sintering. The green body is sintered at a sintering temperature that is higher than the smoothing temperature applied following sintering.
