GOALI: Microwave Sintering of Auto-Ignition Synthesized Nano-Ceramics

这个项目既涉及科学问题，也涉及一个综合项目下的技术发展。从科学的角度来看，该项目涉及合成纳米晶陶瓷，并通过微波烧结等激活固结过程使其致密化。纳米晶材料是指至少具有一个维度lOOnm （1nm -9 m）或更小的颗粒。这些材料有望改变物理和机械性能，只要它们能被巩固，保持纳米晶体结构。然而，这是一项具有挑战性的工作，因为致密化与晶粒生长同时发生。在这项工作中，微波烧结将作为一种激活固结过程。在测定粉体的高温介电性能后确定烧结进度。技术开发将在GOALI计划下进行，其中将涉及几个当地工业联盟。这些行业代表了各种各样的产品，从粉末生产到刀具开发以及电子材料。预计合作伙伴之间将进行广泛的互动。

Bhaduri 9800009 This project involves both scientific issues as well as technical developments under one comprehensive project. From a scientific viewpoint, the project deals with synthesizing nanocrystalline ceramics and densifying them with an activated consolidation process such as microwave sintering. Nanocrystalline materials signify particulates with at least one dimension lOOnm (1nm 10-9 m) or less. These materials are expected to have altered physical and mechanical properties, provided they can be consolidated maintaining the nanocrystalline structure. However, this is a challenging job since densification occurs with concurrent grain growth. In this work, microwave sintering will be used as an activated consolidation process. Sintering schedule will be determined after measuring the high temperature dielectric properties of the powders. The technical developments will be carried out under the GOALI program wherein a consortium of several local industries will be involved. These industries represent a wide variety of products from powder production to cutting tool development as well electronic materials. Widespread interactions are expected to take place among the partners.
