SBIR Phase I: A Low Cost Process for Toughened Ceramics

*96-60960西博尔德这个小型企业创新研究第一阶段项目将开发一种用于增韧氧化铝陶瓷的低成本工艺，这种陶瓷广泛应用于几乎所有行业和市场的磨损、腐蚀和电气绝缘应用。目前，这些陶瓷的脆性和高昂的成本大大限制了它们的使用。这项研究将研究一种低成本的水基陶瓷前驱体，可以用来增韧传统的氧化铝。多孔的商业氧化铝预制体将与该前驱体一起渗透，以开发出片状增韧氧化铝。这将需要的唯一新的加工步骤是在商业陶瓷生产线上最终烧成之前的渗透。商业应用有望在更坚韧的低成本氧化铝陶瓷中实现。***

*** 96-60960 Sibold This Small Business Innovation Research (SBIR) Phase I project will develop a low cost process for toughening alumina ceramics, which are widely used in wear, corrosion, and electrical insulation applications in virtually all industries and markets. Presently, brittleness of these ceramics and their high cost sharply limit their use. This research will examine a low cost, water based ceramic precursor that can be used to toughen conventional aluminas. Porous commercial alumina preforms will be infiltrated with the precursor to develop a platelet toughened alumina. The only new processing step that this would require is infiltration prior to final firing in a commercial ceramic production line. Commercial applications are expected in tougher low cost alumina ceramics. ***
