9860878 This Small Business Innovation Research Phase I project examines the potential for characterizing ceramic powders and fibers using an innovative elliptically polarized light scattering method. Particle size, size distribution, and shape are key factors in manufacturing advanced ceramic materials, which rely on precise mixtures of fine and coarse particles. IOTA's can determine these parameters via a unique approach for optimizing polarization settings. Unlike current on line particle measuring techniques, cylindrical and irregular shapes (such as particle agglomerates) can be evaluated. The ability to discern such shapes can have a great impact for improving ceramic quality and process control, important for product development and reduced costs. This investigation will assess the feasibility of using the system at a ceramic manufacturing site. Fundamental research is proposed to closely examine the accuracy of the instrument (comparing results with electron micrographs) for a variety of particle sizes, shapes, and size distributions. A particle loading study is also proposed to evaluate under what conditions the system can operate. Phase I will focus on evaluating system accuracy and acceptable working conditions for measuring ceramic powders and whiskers. In Phase II a prototype system will be constructed and tested at a ceramic manufacturing plant. Particle agglomeration will also be studied. The ability to measure fine particle sizes and shapes is necessary for controlling the quality of many high technology products, such as advanced ceramics and pharmaceuticals. In addition, monitoring and controlling particle size is fundamental to the manufacture of many consumer products (cosmetics, paints, pigments), textiles, food processing, medical apparatus (parenteral solutions, blood processing), and environmental monitoring.

9860878这个小型企业创新研究阶段I项目研究了使用创新的椭圆极化的光散射方法来表征陶瓷粉末和纤维的潜力。 粒度，尺寸分布和形状是制造高级陶瓷材料的关键因素，这些因素依赖于精确的细颗粒和粗颗粒的混合物。 IOTA可以通过优化极化设置的唯一方法来确定这些参数。 与线颗粒测量技术不同，可以评估圆柱形和不规则形状（例如粒子团聚物）。 辨别这种形状的能力可以对改善陶瓷质量和过程控制产生重大影响，对产品开发和降低成本很重要。 这项调查将评估在陶瓷制造地点使用系统的可行性。 提出了基本研究，以密切检查仪器的准确性（将结果与电子显微照片进行比较），以了解各种粒径，形状和大小分布。 还提出了一项粒子载荷研究，以评估系统可以运行的条件。 第一阶段将着重于评估系统的准确性和可接受的工作条件，以测量陶瓷粉末和晶须。 在第二阶段，将在陶瓷制造工厂构建和测试原型系统。还将研究粒子聚集。 测量精细颗粒尺寸和形状的能力对于控制许多高科技产品（例如高级陶瓷和药品）的质量是必要的。 此外，监测和控制粒径是许多消费产品（化妆品，油漆，颜料），纺织品，食品加工，医疗设备（肠胃外解决方案，血液加工）和环境监测的基础。
