The sol-gel procession of titanium alkoxide was studied through DTA-TG, XRD analysis methods. The study covers the influence of water volume, nitric acid and silver nitrate addition on the gelation time, thermal effects, weight change of sample and anatase-rutile phase transformation temperature. 本文以DTA-TG和XRD等分析方法研究钛醇盐溶胶中水含量、硝酸含量和硝酸银掺杂对胶凝时间、热效应、失重和锐钛矿-金红石相变温度的影响。
