금홍석으로부터 소성법에 의한 Potassium Hexatitanate Whisker의 합성
The Synthesis of Fibrous Potassium Hexatitanate Whisker from Natural Rutile Ore by the Calcination Method
초록
원료 물질로 금홍석과 공업용 K2CO3를 사용하여 소성법으로 육티탄산칼륨 섬유를 제조하였다. 이 육티탄산칼륨 섬유를 얻기 위한 최적 조건은 반응온도 1050℃, 반응시간 3시간이 적절하였으며, K2CO3에 대한 금홍석의 몰비 4.4에서 공업용 규격에 적합한 섬유상을 얻을 수 있었다. 반응 몰비 4.4의 조건으로 합성된 생성물에는 미량의 이티탄산칼륨과 사티탄산칼륨이 혼재해 있으므로 육티탄산칼륨의 단독상은 850℃, 3시간으로 열처리하여 제조하였다.
Fibrious potassium hexatitanate whisker was produced from the calcination process using a mixture of the natural rutile ore and industrial K2CO3. Fibrous Potassium titanate was prepared by the following procedures the starting material consisting of K2O·4.4TiO2 was calcined at 1050℃ for 3 hrs. The calcined products obtained under the above condition consisted mainly of potassium hexatitanate with a small admixture of potassium dititanate and potassium tetratitanate. Therefore the single phase of potassium hexatitanate was obtained by heat treatment of 850℃, 3 hrs.
