前記溶媒は、処理剤が溶解または分散するものであって、霧化または液滴化が可能なものであれば特に限定されず、無機溶媒であってもよいし、有機溶媒であってもよいし、これらの混合溶媒であってもよい。本発明においては、前記溶媒が水であるのが好ましい。
前記処理溶液中の処理剤の含有量は、特に限定されないが、好適には例えば、0.0001〜80重量%であり、より好適には0.001%〜50重量%である。
超音波振動子6は、発振器と接続されており、発振器を作動させると、超音波振動子6から超音波が照射されるように構成されている。超音波が照射されると、容器5内の超音波伝達液5aを介して、超音波振動が原料溶液4aに伝わり、原料溶液4aの霧化または液滴化が生じる。霧化または液滴化により発生したミストまたは液滴は、キャリアガスの供給によって、供給管7内を移動し、管状炉8へと搬送される。
またさらに、上記と同様にして、繰り返し実験を行い、図6に示す透過率と膜厚との関係を導き出した。
