Description
TiCl4+2H2O→TiO2+4HCl;Si(OEt)4+2H2O→SiO2+4EtOH
本発明の範囲内で、「酸化可能」とは、金属化合物が酸素の存在で固体の金属酸化物及びガス状の副生成物へと変換されることを意味するものと解釈される。その例は以下のものである:
ZrCl4+O2→ZrO2+2Cl2
固体形で添加される金属化合物のサイズは、ナノスケール〜数センチメートルの範囲内の寸法であってよい。粒径は、装置パラメータ、例えば火炎温度及び物質パラメータ、例えば金属化合物の蒸発温度の双方に依存する。一般に、固体形で添加される金属化合物のサイズは0.1〜5000μm、有利に1〜1000μmである。
蒸気状の四塩化ケイ素8kg/hをバーナーの混合室に移送する。同時に、水素4.5m3(STP)/h及び一次空気11.9m3(STP)/hを混合室に導入する。混合物に点火し、火炎燃焼させ、反応室に流入させる。塩化カリウム21g/hを計量供給スクリューを用いて火炎中に計量供給する。更に、反応室に二次空気30m3(STP)/hを導入する。フィルター又はサイクロンにおいて、固形物を排ガス流から取出し、次いで水蒸気で約500℃の温度で処理する。
