求大神翻譯外文摘要 謝謝
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.

本工作的重點放在通過向二氧化硅氣溶膠基質(zhì)中添加赤鐵礦來合成紅色無機陶瓷顏料的方法上面。在煮沸了的濃鹽酸(36 wt%)中的浸出實驗表明,以二氧化硅氣溶膠和人工合成的針鐵礦的混合物為原料在 1150~1200°C 的溫度下煅燒 2~4 小時就生成赤鐵礦。使用比表面積300~400m2/g的二氧化硅氣溶膠為原料時可得到更好的結(jié)果。通過比較煅燒樣品的L-a-b的數(shù)值可以連續(xù)地測量產(chǎn)品顏色的變化,更多的信息還可通過 Kubelka- Munk 吸附函數(shù)來獲得。因為產(chǎn)品的化學和熱學的良好穩(wěn)定性,這種性能特異的顏料也許適合用于具有快速燒制周期生產(chǎn)工藝的陶瓷所需的顏料。

本工作重點是將赤鐵礦(粉)包在薰過的硅石基質(zhì)中以合成紅色無機陶瓷顏料。沸濃鹽酸(36 wt%)浸出試驗表明,將薰過的硅石和人工合成針鐵礦的混合物在 1150~1200°C 的溫度下煅燒 2~4 小時就可發(fā)生赤鐵礦吸留(包藏)。使用比表面積300~400m2/g的硅石效果更好。 比較煅燒樣品的L-a-b的數(shù)值可測出產(chǎn)品顏色的連續(xù)變化,更多的信息可通過 Kubelka- Munk 吸附函數(shù)獲得。由于(產(chǎn)品的)抗腐蝕耐高溫(化學和熱學的良好穩(wěn)定性),(所獲得的)這種多晶型顏料可認為是一種適用于陶瓷快速燒制生產(chǎn)的紅色顏料,
