Temperature rising behavior of oxide materials synthesized Ⅴ-Al alloy and slag after reaction in microwave field
The absorption of microwave energy has very close relationship with the structure and property of material.For the preparation of Ⅴ-Al alloy with using microwave-assisted self-propagating,it is essential to choose the proper materials with suitable properties and quantities.The temperature-rise can be obtained by the interaction between microwave field and materials,and then the aluminothermic reaction can be controlled in the microwave field.In this paper,the temperature-rise behaviors of Al2O3,CaO,V2O5 and the slag alter reaction under microwave field were investigated.The results showed that either the microwave power or the molecular structure of materials had significant effects on the heating rate.The relationship between temperature-rise behavior of different materials and the material structures were discussed through studying the difference of molecular structures,which led to the conclusion that the more structure defects in the crystal,the faster the heating rate was.
