由於近年研究發現微波加熱較傳統加熱有優勢，而材料的特性是決定微波加熱情況的關鍵，所以本論文我們建構了一個可以進行材料處理，以及量測材料特性的實驗系統，最高可以將SiC加熱到670℃。但因為常溫的材料特性是熟知的，而材料特性隨溫度的變化則不清楚，所以我們用了兩種腔體微擾法來量測材料SiC在不同溫度時的介電常數。用傳統的腔體微擾法量測，其優點是使用上較為方便，但缺點是適用性不廣泛，其要求材料的體積要遠小於腔體的體積，並且空腔的電場分布要相近於腔體內有材料的情況。所以我們提出另一個腔體微擾法，其適用的較為廣泛，沒有傳統的腔體微擾法的缺點，所以可以得到比較準確的數值。我們也做了實驗，運用兩種理論計算出不同溫度的SiC的介電常數，並進行比較，發現介電常數的實部結果差不多，但是介電常數的虛部則有顯著的差異，我們提出的方法有校正的效果。
