A composition of a ceramic pigment has been developed using pyroxenite, including pyroxene minerals — augite and enstatite—with forsterite, serpentine and coloring oxides of iron and chromium being present. The compositions of the crystalline phases in pigments were investigated by means of XPAand microanalysis as a function of the firing temperature. A ceramic pigment with diopside structure makes it possible to obtain a brown coating when using the pigment in a wide range of firing temperatures 850 – 1250°C, excluding melting of the pigment while improving the purity of tone and brightness of the coating.

辉石基陶瓷颜料

已经开发了使用辉石的陶瓷颜料组合物，其中包括辉石矿物（辉石和顽辉石）以及镁橄榄石，蛇纹石以及铁和铬的有色氧化物。借助XPA和微观分析研究了颜料中晶相的组成与焙烧温度的关系。具有透辉石结构的陶瓷颜料可以在850至1250°C的宽范围烧成温度下使用时获得棕色涂层，不包括颜料的熔化，同时还可以提高涂层的色调纯度和亮度。
