  摘要：

  It was previously established that kaolinite reacts with K2CO3 on heating to form products of KSiAlO4 composition. In the present study we investigated the solid state reactions with K2CO3 Of four kaolinites of different thermal stability. The mixtures were calcined at temperatures ranging from 400-700degreesC and washed before or after boiling with the remaining K2CO3. FTIR spectra indicated that the X-ray amorphous material formed after calcining the mixtures at 500-590degreesC had a SiAlO4 tetrahedral framework. Attempts to convert the products to zeolites gave promising results. After calcining at 700degreesC under atmospheric pressure synthetic kaliophilite (KSiAlO4) was obtained. These conditions are appreciably milder than previously reported for kaliophilite syntheses. Conversion to kalsilite increased with decreasing thermal stability of the original kaolinite.In similar reactions with KCl much less K was incorporated into the amorphous phase and kaliophilite was not obtained. The reactions of the four kaolinites with K2CO3 or with KCl were similar in trend, but differed in detail.

  science and implications for the geology field. The present studies on phase relations of the Fe-free and Fe-bearing nepheline-kalsilite systems have demonstrated that 10 mol % of Fe 3+ substitution in Al 3+ does not affect the phase relations of the solid solutions but causes the increase of lattice parameters. Analysis of the Mossbauer spectra has indicated that low-temperature carnegieite, low-temperature

  摘要 霞石-钾长石（NaAlSiO 4 -KAlSiO 4 ）体系中的结晶溶液形成了重要的成岩结构硅酸盐，在材料科学和地质领域具有重要应用。目前对无铁和含铁霞石-钾长石体系相关系的研究表明，Al 3+ 中10 mol %的Fe 3+ 取代不影响固溶体的相关系，但会引起晶格的增加。参数。穆斯堡尔谱分析表明，Na(Al 0.9 Fe 0.1 )SiO 4 -K(Al 0.9 Fe 0.1 )SiO 4 体系中的低温碳镁石、低温霞石和正交KAlSiO 4 O1 相只有一个双峰分配给具有四面体配位的高自旋 Fe 3+，
