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

巴伦9613068氧化铝的传统合成和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。本研究项目的目的是为氧化铝陶瓷的制备开发环境友好的工艺。研究的重点是：(1)设计不使用有毒试剂或溶剂的氧化铝陶瓷的替代合成路线；(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；(3)应用新材料和新工艺，开发一种成本效益高的方法，以高效地防止污染和回收资源。该项目的范围包括对氧化铝前驱体的水处理、将其加工成可成形的泥料以及由该泥料制造固体陶瓷体的基础研究。这项研究的目标是两个潜在的应用：(1)高密度流延氧化铝基板；(2)多孔超滤和纳米滤膜。这些改进在污染防治方面具有潜在的应用前景。

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.
