摘　　要：Mineralizing mechanism of three mineralizers in dry synthesizing of cordierite in talc-clay-ommercial alumina system has been investigated.Cordieite grog containing 95% cordierite phase has been synthesized by this technique ,The synthesized cordierite has well-developed cordierite crystals with network structure,its ,thermal expansion coefficient α=2.4×10^－6／℃(20℃-1000℃），And cordierite-mullite deck with high perfomance has been developed by using the raw cordierite co-grinding powder as the matrix and hight-grade mullite grog as the aggregate.
