This Small Business Innovation Research Phase I project will develop an innovative and versatile low-pressure injection molding (LPIM) process for the fabrication of net-shape ceramic components. LPIM has been recently recognized as an attractive process for the fabrication of high-precision, complex-geometry ceramic parts. However, one major factor that limits the use of injection molding process for production is the lack of reliability and throughput. Thus, there is an immediate need for technologies that can substantially improve the LPIM process. This project will utilize a low-pressure injection molding approach for the net-shape forming of high performance ceramics reliably and at low cost. Specific innovations include: utilizing an environmentally-safe solvent extraction debinder technique, improving the thermal conductivity of the current binder system, and demonstrating an improved fabrication versatility that is relatively insensitive to material and size constraints.The commercial benefits will be to alumina ceramic based cross-flow particulate filtration systems for liquid waste streams; mullite based filters for hot gas streams; NZP based engine liners; and alumina based element holders for furnaces.

该小型企业创新研究第一阶段项目将开发一种创新且多功能的低压注塑 (LPIM) 工艺，用于制造净形陶瓷部件。 LPIM 最近被认为是制造高精度、复杂几何形状陶瓷零件的一种有吸引力的工艺。然而，限制注塑工艺用于生产的一个主要因素是缺乏可靠性和产量。因此，迫切需要能够大幅改进 LPIM 工艺的技术。该项目将采用低压注射成型方法，以可靠且低成本的方式实现高性能陶瓷的净成型。具体创新包括：利用环境安全的溶剂萃取脱粘合剂技术，提高现有粘合剂系统的导热性，并展示对材料和尺寸限制相对不敏感的改进的制造多功能性。商业利益将在于基于氧化铝陶瓷的液体废物流错流颗粒过滤系统；用于热气流的莫来石过滤器；基于 NZP 的发动机衬套；以及用于熔炉的氧化铝基元件支架。
