METHOD FOR BONDING BETA ALUMINA AND ALPHA ALUMINA BY USING ALUMINA AND CALCIUM OXIDE AND UNIT HEAT CONVERSION GENERATOR USING SAME

摘要

To meet the following challenge, the present invention uses mixed powder of alpha alumina and calcium oxide (CaO) as a basic adhesive for bonding. More specifically, the present invention provides a technology which does not need to separately bond an alpha alumina component by manufacturing an alpha alumina-integrated type bonding component. A technology which is used for a direct bonding is also provided by applying the mixed powder of alpha alumina and carbon oxide (CaO) to a part between the beta alumina and the alpha alumina. The mixed powder of the alpha alumina and the carbon oxide (CaO) is melted at a lower temperature than normal alumina by forming an eutectic point when heating the mixed powder at a temperature of 1300-1500C and thereby induces a bonding of alpha-beta-alumina.;COPYRIGHT KIPO 2014
