内容简介

It is necessary for improving the service life that the increase in ZrO_2 content should be compatible with the decrease in a apparent porosity. It was determined that the corrosion resistance of ZG materials containing less than 86 percent of ZrO_2 was deteriorated because of the increase in apparent porosity, for the same compaction pressure. On the basis of the above knowledge, the authors prepared an improved mix, which had improved corrosion resistance, and confirmed the compatibility of corrosion resistance with thermal shock resistance.
