9318415 Kingery The objective of this research is to improve the reliability and effectiveness of additive-promoted sintering of ceramics. This process constitutes the vast majority of competitive commercial practice. This requires researching the distribution of additives (i.e., their wetting behavior) and chemistry during the entire process of heating and cooling. The scientific importance of this study is to refocus sintering paradigms away from formally correct but often irrelevant isothermal models towards the more complex and substantial changes occurring during heating and cooling. %%%% The practical importance of the research will be to establish a basis for obtaining enhanced quality and reliability and performance by using a sol-gel process for optimally positioning a small fraction of critical additive. ***

小行星9318415 本研究的目的是提高添加剂促进陶瓷烧结的可靠性和有效性。 这一过程构成了绝大多数竞争性商业惯例。 这需要研究添加剂的分布（即，它们的润湿行为）和在整个加热和冷却过程中的化学性质。 这项研究的科学重要性是重新聚焦烧结范式，从形式上正确但往往不相关的等温模型转向加热和冷却过程中发生的更复杂和实质性的变化。 %%%% 该研究的实际重要性将是建立一个基础，通过使用溶胶-凝胶工艺来优化定位一小部分关键添加剂，从而获得更高的质量、可靠性和性能。 ***
