Said metal nitride is prepared through mixing the aqueous soltuion of nitrate or sulfate of A with the aqueous soltuion of Cr, Mo or W acid or one of their ammonium salts, coprecipitation or impregnation to obtain load-type or non-load-type dual-component metal salt or compound oxide, then pass in NH3, sequentially heating and azotizing at 600-750 deg.C.

该金属氮化物是由含A过渡金属元素的硝酸盐或硫酸盐水溶液与Cr、Mo或W酸或者Cr、Mo或W酸铵水溶液混合，通过共沉淀法或浸渍法制成负载型或非负载型双组元金属盐或复合氧化物，再将双组元金属盐或复合氧化物通NH3进行程序升温，至最终氮化温度600～750℃下进行反应而制得。

Tina's turmoil: I have been along time reader of another blog called Killer Strands and the writer (Dakota Ellis/Killer Chemist) is a hair colourist and a cosmetic chemist who has tested sulphate shampoos and proved it does fade color and may cause premature hair loss.

不久前我读过一篇名为《头发杀手》的博客，作者是一个发型师和化妆品药剂师，她叫达科达。埃利斯。她对含硫酸盐的洗发水作了试验并且证实这种酸性洗发水会导致头发掉色和早脱。
