高频感应等离子法与直流电弧法相比 ,等离子体的容积大 ,直径达几十毫米 ;等离子流速小 ,每秒几十米 ,可在氧化、还原多种反应气体中进行。因此 ,可以合成在形态、结晶构造、化学组成等方面与以往不同的材料。最近 ,二氧化钛用作光催化材料、抗菌材料已受到极大关注 ,还正在研 High-frequency induction plasma method compared with the DC arc method, the plasma volume, the diameter of tens of millimeters; plasma flow rate of small, tens of meters per second, in oxidation, reduction of a variety of reactive gases. Therefore, it is possible to synthesize a material different from the conventional one in terms of morphology, crystal structure, chemical composition and the like. Titanium dioxide has recently been used as a photocatalytic material, and antibacterial materials have received great attention and are being researched
