Environmentally-Conscious Manufacturing: Environmentally-Benign Chemical Synthesis and Processing of Alumina-Based Ceramics

巴伦 9613068 传统的氧化铝制备方法是传统的陶瓷法和溶胶-凝胶法，这两种方法都对环境造成了严重的影响。本研究计画的目的是发展环保的氧化铝陶瓷制程。 研究的重点是：（1）设计一种不使用有毒试剂或溶剂的氧化铝陶瓷替代合成途径;（2）应用新材料作为现有技术的替代品，以防止或减少对环境的危害;以及（3）将新材料和新工艺应用于开发高效污染预防和资源回收的成本有效方法。 该项目的范围包括对氧化铝前体的水处理的基础研究，将其加工成可成型的泥浆，以及从该泥浆中制造固体陶瓷体及其特性。 该研究针对两个潜在的应用：（1）高密度流延氧化铝基板;（2）多孔超滤膜和纳滤膜。 这些改进在污染防治中具有潜在的应用价值。

Barron 9613068 The traditional methods for alumina synthesis and fabrication are traditional ceramic methods and sol-gel, both of which have serious environmental impacts. The objective of this research project is to develop environmentally-benign processing for the fabrication of alumina ceramics. The research is focused on the following tasks: (1) design of an alternative synthesis pathway to alumina ceramics which does not utilize toxic reagents or solvents; (2) applying the new materials as alternatives to present technology to prevent or reduce environmental harm; and (3) applying the new materials and processes to the development of a cost effective method for the highly efficient pollution prevention and resource recovery. The scope of the project includes fundamental research into aqueous processing of alumina-precursors, their processing into a formable slip, and the fabrication and characteristics of solid ceramic bodies from this slip. The research is targeted to two potential applications: (1) high-density tape-cast alumina substrates; and (2) porous ultra- and nano-filtration membrane. These improvements have potential applications in pollution prevention and control.
