This Small Business Innovation Research (SBIR) Phase I project is a feasibility study to produce two-submicron inorganic powders via solvent-free processing routes. One of the materials is the anionic clay known as hydrotalcite, which is used as an antacid and a PVC additive. The other material is a glass-zirconia composite, which is a promising candidate for making glass-ceramic dental materials. Structure-function relationships suggest that production of these two types of inorganic powders in particle sizes at or below one micron should translate into materials with improved performance over commercially available forms. For both target materials, the key advantages over current manufacturing methods are simplicity in terms of the processing steps; solvent-free manufacturing; and cost. Mechanochemical production of submicron powders should also compete favorably with more exotic syntheses leading to nanosized powders.

这个小型企业创新研究（SBIR）第一阶段项目是一个可行性研究，通过无溶剂加工路线生产两个亚微米无机粉末。 其中一种材料是被称为水滑石的阴离子粘土，它被用作抗酸剂和PVC添加剂。另一种材料是玻璃-氧化锆复合材料，这是一种很有前途的候选人，使玻璃陶瓷牙科材料。结构-功能关系表明，这两种类型的无机粉末的颗粒尺寸在或低于1微米的生产应转化为具有比市售形式更好的性能的材料。对于这两种目标材料，相对于当前制造方法的关键优势是加工步骤简单;无溶剂制造;和成本。亚微米粉末的机械化学生产也应该有利地与导致纳米级粉末的更奇异的合成竞争。
