微波法制备γ-Al_2O_3蜂窝陶瓷涂层的实验研究

Experimental Research on γ-Al_2O_3 Honeycomb Ceramic Coating by Microwave Process

采用微波加热法制得了γ-Al2O3蜂窝陶瓷涂层及相应的三效催化剂.比较并详细分析了微波涂层（TC-B）与传统涂层（TC-A）在晶型、比表面积及三效催化剂活性上的差别.结论是.微波涂层的主要特性参数均达到或超过了传统涂层.以微波法制备γ-Al2O3涂层的工艺过程能耗少、周期短、生产成本低.

A kind of honeycomb ceramic coating was prepared by using microwave heating methods. Differences on specific area, crystal and catalytic activity between the microwave coating (TC-B) and the normal coating (TC-A) were tested and analyzed too. The results show that the main characteristic parameters of the coating by microwave process are as good as, if not better than, that of the coating by existing process. Using microwave process to prepare γ-Al2O3 honeycomb ceramic coating can save large amount of energy, time and cost.
