Abstract

This article deals with the investigations on mullite ceramics formation from Kyanite sample- an alumino-silicate mineral with microwave heating. In the present investigation kyanite was heated in microwave sintering furnace with calcined alumina, silicon carbide, zirconium dioxide and binder for mullite formation as well as for the preparation of zirconia toughened mullite product. The results of these studies reveal that how a small amount of zirconium dioxide helps in toughening the mullite formation for refractory and ceramics applications. The results shows that microwave heating method is one of the most novel and eco-friendly process for such toughened mullite formation, well within very short period of time. The observations with mullite formation and zirconia toughened mullite formation were observed with the structural data using X-ray diffraction data, field effect scanning electron microscope and energy dispersive spectroscopy. Future studies are still in process.

摘要

本文涉及从蓝晶石样品（一种采用微波加热的铝硅酸盐矿物）形成莫来石陶瓷的研究。在本研究中，蓝晶石在微波烧结炉中与煅烧氧化铝、碳化硅、二氧化锆和粘合剂一起加热以形成莫来石以及制备氧化锆增韧莫来石产品。这些研究的结果表明，少量的二氧化锆如何有助于在耐火材料和陶瓷应用中增韧莫来石的形成。结果表明，微波加热法是这种增韧莫来石形成的最新颖、最环保的工艺之一，而且在很短的时间内。使用X射线衍射数据、场效应扫描电子显微镜和能量色散光谱法观察了莫来石形成和氧化锆增韧莫来石形成的结构数据。未来的研究仍在进行中。
