微波固相法合成硼酸镁晶须

Preparation of Magnesium Diborate Whisker By Microwave Irradiation

应用微波合成技术，以氧化锌为加热介质，合成出了硼酸镁（Mg2B2O5）晶须，与常规固相反应相比，微波法可在微波辐射下（2．450Hz）仅20min内使反应完成。在详细研究相转变的同时，对微波在固相合成中的作用进行了初步的讨论。

Magnesium diborate whisker has been successfully prepared by a new method-microwave irradiation. The preparation of reaction was processed in a commercial microwave oven operation at 2. 45GHz. We used ZnO as heating medium in order to induce the temperature. The fast reaction by microwave irradiation was observed. The Microwave solid state reaction was completed within only 20 min. The possible effect of the microwave irradiation on the solid state reaction was discussed.
