摘要
Abstract
The green compact properties of ZrO2 spray-dried powders were studied by means of pressure-density compaction curves of the powder and SEM photographs . The results show found that the granule size distribution of the spray-dried powder has a smaller effect on the green compact density . Granule yield strength, which depends on the dimension of granules and the relative humidity in the environment, is a critical factor influencing the uniformity of green compact microstructures . Therefore, plasticizing granules and eliminating larger granules can improve the microstructure of the green compact .关键词
