An MS-1301 high-temperature mass spectrometer was used in the experiments and quartz effusion cells with the sublimation surface-to-effusion orifice area ratio of about 3000 were employed. The vapor above the system consists of Zn(g), and O2, which corresponds to the incongruent vaporization of Zn7In2O10 and Zn5In2O8.

Sep 09, 2015 · Sintering furnaces therefor on the market are for the most part convection types, very similar to porcelain ovens, as it produces more esthetic results. Question: Does the Yttria content alter the zirconia's time to sinter or high sintering temperature? Answer: Yttria is a stabalizer as zirconia by itself is an unstable element.

It was found that cracking was accelerated by external tensile stress, high fibre permeability, moderate fibre orientation, and water-plasticization. It was also found that the cracking process was a sensitive indicator of residual latent strain in the fibre, which may persist after high-temperature annealing.
