Abstract:The elemental requirements for electronic packaging substrate materials were summarized. The polymorphic transformation and typical properties of alumina were introduced. Three synthesis methods of alumina ultrafine powder were discussed, namely solid phase, gas phase and liquid phase methods. The effect of alumina ceramics sintering additives and six kinds of sintering technologies were analyzed, namely pressureless sintering, hot pressing sintering, high temperature isostatic pressing, microwave sintering, microwave plasma sintering and spark plasma sintering. The development trends of alumina ceramics substrate materials were pointed out.

 

Key words: electronic packaging materials; alumina ceramics; ultrafine powder; sintering additives; sintering technologies
