Abstract

ZrSiO4-based pigments have been known to be very stable in ceramic glazes but require a high firing temperature required for phase formation. This study examined the feasibility of using rice husk waste as a substitute for crystalline SiO2. The amorphous form of silica with some impurities was obtained by calcining the rice husk at 800℃. The general chemical formula were (Zr0.9M0.1)SiO4, where M = V, Pr, Fe and Cr. The solid-state processing was achieved by firing at 1300℃ for 12 h with NaF (5 wt%). X-ray Diffraction revealed a lower relative fraction between ZrO2 (secondary phase) and ZrSiO4 in the RHA systems compared to the oxide system for all dopants. Amorphousness of RHA did help enhance phase formability. The particle sizes were in the 3 µm to 5 µm range. Elemental analysis revealed some areas with intense signals of zirconium, indicating unreacted ZrO2 particles. Colorations appeared to be blue, yellow, brown and green for dopants of V, Pr, Fe and Cr, respectively. Technological performance was tested in a practical ceramic glaze and frequently used raw materials fired at its maturation point. The results of this study hold huge potential for using rice husks for sustainable manufacturing of pigments as green products.

稻壳灰合成锆英石颜料及其在陶瓷釉中的性能

众所周知，zrsio4基颜料在陶瓷釉中非常稳定，但需要较高的烧成温度才能形成相。本研究考察了利用稻壳废料代替结晶SiO2的可行性。将稻壳在800℃下煅烧得到含杂质的无定形二氧化硅。一般化学式为(Zr0.9M0.1)SiO4，其中M = V, Pr, Fe和Cr。采用NaF (5wt %)在1300℃下烧制12 h，实现固态加工。x射线衍射显示，与所有掺杂剂的氧化物体系相比，RHA体系中ZrO2(二次相)和ZrSiO4的相对分数较低。RHA的非晶性确实有助于提高相的成形性。粒径范围为3µm ~ 5µm。元素分析显示，一些区域有强烈的锆信号，表明未反应的ZrO2颗粒。V、Pr、Fe和Cr的掺杂剂分别呈现蓝色、黄色、棕色和绿色。在实际陶瓷釉料和熟化常用原料中进行了工艺性能测试。这项研究的结果为利用稻壳作为绿色产品可持续生产颜料提供了巨大的潜力。
