brookite

基本解释

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钛矿相和锐钛矿相组成的混晶样品。
Consequently, rutile transformed into brookite up to the pH value of 10 and brookite became more while continuously increasing the amount of HMT.
当pH值达到10时，金红石相转变为板钛矿相，随着六亚甲基四胺加入量的继续增多，板钛矿相也逐渐增多。
However, silver ions not only promoted (or catalyzed) the formation of brookite phase but also reduced the phase transformation temperature of anatase to rutile.
同时，Ag+离子的掺杂不仅促进了钣钛矿的形成，并且降低了锐钛矿向金红石相的转变温度。
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.
当AgNO_3浓度高于0.;03 M时，Ag-TiO_2复合薄膜由锐钛矿、金红石、钣钛矿、金属银颗粒组成，它们的晶粒尺寸范围在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值趋向于生成锐钛矿相，高pH值趋向于生成金红石相，而压力增大导致的碱性增强是促进板钛矿相形成的主要因素。
