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

巴杜里 9800009 该项目在一个综合项目下既涉及科学问题，也涉及技术发展。从科学的角度来看，该项目涉及合成纳米晶体陶瓷，并通过微波烧结等活化固结工艺使其致密化。纳米晶体材料是指至少一维尺寸为100 nm（1 nm 10-9 m）或更小的颗粒。这些材料预期具有改变的物理和机械性能，只要它们可以被固结保持纳米晶体结构。然而，这是一个具有挑战性的工作，因为致密化发生与并发的晶粒生长。在这项工作中，微波烧结将被用作活化固结过程。烧结方案将在测量粉末的高温介电性能后确定。 技术开发将在GOALI计划下进行，其中将涉及几个当地行业的财团。这些行业代表了从粉末生产到切削工具开发以及电子材料的各种产品。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.
