英文摘要 | 研究了KAIF_4与简单氟化物,与KBF_4,K_3AIF_6,K_3GaF_6,K_3YF_6,KBe_2F_5等不同类型化合物组成的赝二元系的相图.相图结果表明,化合物组成与KAIF_4愈相似者对KAIF_4的熔点影响愈大,共晶熔液中含这个化合物的浓度也愈大.简单氟化物800℃以下在KAIF_4熔液中难溶由此推断KAIF_4 熔液由KAIF_4分子和K~+以及AIF_4~-组成.KAIF_4分子相对稳定,并占主要成分; Many quasi-binary phase diagrams which comprised of KAlF4 with other fluorides or complex fluorides have made by visual-polythermal, DTA and XRD methods. Results indicated that the more composition of second components is similar to that of KAlF4, the more influence on liquid and eutectic of the system would be observed. Stable and simple fluorides are difficultly soluble in molten KAlF4 below 800 degrees C. From mentioned, it is deduced that the structure of molten KAlF4. appears to be comprised of molecular KAlF4 as well as ions K+ and AlF4-. Molecular KAlF4 is relatively stable and is the main part in the melt.; SCI(E); 中文核心期刊要目总览(PKU); 中国科学引文数据库(CSCD); 2; 08; 765-768; 53 |
