Engineering Equipment Grant: Rapid Solidification of Oxide Ceramics

氧化物陶瓷的快速凝固是一种新的加工技术，它可以获得其他加工技术所不能获得的材料的组织和性能。这项提议是为了购买一台感应加热装置，将氧化物加热到熔点，然后快速凝固。这些材料在结构、磁性、电气和超导应用以及生产独特成分的玻璃方面具有巨大的潜力。两类氧化物体系，含陶瓷的ZrO2和MBa2Cu3O7-x(M=Y，Dy，Gd)超导体将用感应加热熔化，并用双辊淬火快速凝固。这些材料将通过差热分析、扫描和透射电子显微镜以及X射线衍射进行检测。

Rapid solidification of oxide ceramics is a novel processing technique which can yield materials with microstructures and properties which cannot be obtained by other processing techniques. This proposal is for the purchase of an induction heating unit to heat oxides to their melting point and then rapidly solidify them. These materials have enormous potential for structural, magnetic, electrical, and superconducting applications as well as producing glasses of unique compositions. Two classes of oxide systems, ZrO2 containing ceramics and MBa2Cu3O7-x (M=Y,Dy,Gd) superconductors will be melted by induction heating and rapidly solidified by twin roller quenching. These materials will be examined by differential thermal analysis, scanning and transmission electron microscopy and x-ray diffraction.
