brookite

基本解釋

The mixed crystallite consisting of brookite and anatase has the best photocatalytic activity in the all samples.
光催化活性最好的是由板鈦礦相和銳鈦礦相組成的混晶樣品。
Consequently, rutile transformed into brookite up to the pH value of 10 and brookite became more while continuously increasing the amount of HMT.
當pH值達到10時，金紅石相轉變?yōu)榘邂伒V相，隨著六亞甲基四胺加入量的繼續(xù)增多，板鈦礦相也逐漸增多。
However, silver ions not only promoted (or catalyzed) the formation of brookite phase but also reduced the phase transformation temperature of anatase to rutile.
同時，Ag+離子的摻雜不僅促進了鈑鈦礦的形成，并且降低了銳鈦礦向金紅石相的轉變溫度。
When AgNO_3 concentration was higher than 0.03 M, the prepared samples consisted of anatase, brookite, rutile and metal silver nanocrystal particles, and their grain size ranges were 5-30 nm.
當AgNO_3濃度高于0.;03 M時，Ag-TiO_2復合薄膜由銳鈦礦、金紅石、鈑鈦礦、金屬銀顆粒組成，它們的晶粒尺寸范圍在5-30 nm。
So it is concluded that anatase is easier to form at lower pH value, but rutile at higher pH value.Ascent of base strength from increase of pressure can promote the formation of brookite.
因此在低pH值趨向于生成銳鈦礦相，高pH值趨向于生成金紅石相，而壓力增大導致的堿性增強是促進板鈦礦相形成的主要因素。
