Abstract

The relatiop between change of sodium oxide in ceramic shell mould and its mechanical properties at high temperature were studied by using chemical analysis

X-ray diffraction analysis

polarization microscope and DTA

etc.

The reaction mechanism of high temperature and production control of sodium oxide were also discussed.
