chemical homogeneity meaning in Chinese

化学均匀性
化学均质性

The influence of preparing conditions on aluminum titanate composing was inquired . by analyzing element content of alumina and titania source , arranging a stoichiometric dosage , and keeping the chemical homogeneity from sol to mixed ti - al oxide precursor , a high activity powder was prepared . after calcining the precursor powder at 1250 for 2h , aluminum titanate phase is formed
本试验通过准确测定起始物的ti 、 al含量，严格化学配比，采取适当措施将微尺度上的组成均匀性从溶胶一直保持到混合铝钛氧化物前驱体的生成，使该粉体具有高活性，将其在1250煅烧2h ，已合成出以钛酸铝为主晶相的产物，比文献报道的钛酸铝相的最低生成温度降低了50 。
