你真丑

新虫 (初入文坛)

[求助] 求大神翻译外文摘要 谢谢已有2人参与

The work focuses on the syntheses of red inorganic ceramic pigments by inclusion of hematite in a fumed silica matrix. Leaching tests in boiling solutions of concentrated (36 wt%) hydrochloric acid demonstrated that, starting from mixtures of fumed silica and synthetic goethite, the occlusion of hematite occurs by calcination at 1150 –1200°C for 2– 4 h. Better results were obtained by using fumed silica having surface area ranging from 300 to 400 m2/g. A continuos change in colour was measured by comparing L-a-b values of the calcined samples and more information were obtained by the Kubelka- Munk absorption function. Because its chemical and thermal stability, the obtained heteromorphic pigment may be considered a suitable red pigment for ceramic manufacturing by fast firing cycles.

本工作的重点放在通过向二氧化硅气溶胶基质中添加赤铁矿来合成红色无机陶瓷颜料的方法上面。在煮沸了的浓盐酸(36 wt%)中的浸出实验表明,以二氧化硅气溶胶和人工合成的针铁矿的混合物为原料在 1150~1200°C 的温度下煅烧 2~4 小时就生成赤铁矿。使用比表面积300~400m2/g的二氧化硅气溶胶为原料时可得到更好的结果。通过比较煅烧样品的L-a-b的数值可以连续地测量产品颜色的变化,更多的信息还可通过 Kubelka- Munk 吸附函数来获得。因为产品的化学和热学的良好稳定性,这种性能特异的颜料也许适合用于具有快速烧制周期生产工艺的陶瓷所需的颜料。
