I have a flat support of 6 cm (Al2O3 obtained by dry pressing) and need to reduce it to 3.8 cm for test in the gas permeation module. The rsintering shrinkage was not enough, how could I cut this support?
Which dimension you are speaking about? Length? Width? Height? If you need just to shorten (length reduction) your part, ensure that it is sintered properly and then cut it gently with thin diamond saw.
