Thermal stability is an important parameter of amorphous material, and is an inevitable subject in amorphous matter research.

热稳定性是非晶材料的重要参量，是非晶材料研究中不可回避的课题。

Ti-Si composite materials are mixed at atomic scale, and Ti-O-Si bond appears in all of the samples with different TiO2 content; the mixed oxides are mainly existed in the form of amorphous pattern, anatase appears when the TiO2 content is more than 80%, but compared with the intension of pure TiO2, it has not integrate structure. The acetic content has great influence in the specific area and crystal structure of the mixed oxides. 20TiSi has good heat stability, still possesses 11m2/g after calcined at 1100℃; calcinations on the large scale of temperature does not cause the break of Ti-O-Si bond, TiO2 is well dispersed in 20TiSi calcined at 1100℃, and it still existed in the form of amorphous.

结果表明：制得的Ti-Si复合氧化物具有很高的比表面积，在TiO_2含量为10％时达到681.5m~2／g，Ti原子进入Si-O四面体结构中，形成Si-O-Ti键，复合氧化物的稳定性好，当TiO_2含量低于60 wt％时，以无定型形式存在；当含量为80％时，出现锐钛矿型TiO_2，但与纯TiO_2相比晶型不完整：醋酸对Ti-Si复合氧化物的比表面积、晶型都有很大的影响；TiO_2含量为20％的20TiSi经1100℃高温焙烧后，仍有较高的比表面积(11m~2／g)，稳定性好，在较宽的温度范围内焙烧，没有引起Ti-O-Si键的断裂，分散度高，没有出现晶型TiO_2。
