摘要
以菱铁矿为主要原料与传统陶瓷原料(长石、石英、粘土和透辉石等)相结合进行磁性日用陶瓷的研制,同时进行了坯釉适应性的尝试。根据烧成样品的测试和分析结果表明,菱铁矿作为陶瓷原料是可行的,磁化后表现出较高的磁性强度,并且该坯体与研制的玻璃釉匹配良好。
The study on magnetic household ceramics will contribute much to the further utilization of related new material resources and energy conservation in ceramics firing. Various formulas (with siderite, feldspar, quartz, diopside, etc. mixed in proportion to each other) and firing conditions were systematically investigated with regard to magnetism, strength, and color or glossiness. In the experiments, different formulas with siderite and energy saving material (diopside) varying in content were tried. Finally, the sample with high magnetism fired at a relatively low temperature was obtained. The optimum process is: firing at around 1050±5°C for half an hour in oxidizing atmosphere, which guaranteed the transformation of Fe2+ to Fe3+. Through the X-ray analysis, large amounts of α-Fe2O3 and γ-Fe2O3 have been found in the porcelain bodies. According to the magnetism test, the magnetic susceptibility of all bodies is lower than 8×103, immediately next to high magnetic minerals. It is also concluded that the higher the amount of siderite, the higher the magnetism. In addition, the glaze was also investigated. The firing results of glazed ceramics show that the fitness between the body and the glaze is good, and the color, glossiness and strength are desirable, too.
