在这项研究中，VxTi1-xO2（0小于或等于x小于或等于0.20）金红石固溶体是由V(IV)氧基乙酰丙酮酸酯和Ti(IV)异丙醇混合物（聚合凝胶）水解缩合而成的凝胶合成的。这些固溶体在高温（1200-1400℃）下稳定并进入釉料。釉料的着色以及这些金红石固溶体的热稳定性表明它们作为灰色陶瓷颜料的潜在用途。将获得的结果与从 V2O5 和 TiO2（锐钛矿）混合物（陶瓷法）获得的结果进行比较。当 x < 0.10 时，醇盐在釉料上会出现明显的颜色变化。
In this study, VxTi1-xO2 (0 less than or equal to x less than or equal to 0.20) rutile solid solutions have been synthesized from gels built from hydrolysis-condensation of V(IV) oxyacetilacetonate and Ti(IV) isopropoxide mixture (polymeric gel). These solid solutions are stable at high temperature (1200-1400degreesC) and into glazes. The colouration of the glazes together with the thermal stability of these rutile solid solutions indicates their potential usefulness as gray ceramic pigments. The results obtained are compared with those obtained from V2O5 and TiO2 (anatase) mixtures (ceramic method). From alkoxides, noticeable change in coloration is obtained on glazes, when x < 0.10.
