莫来石是瓷器显微结构之一,是构成瓷器机械强度的主要因素。莫来石瓷具有良好的电性能,抵抗强酸、碱、盐侵蚀的能力,线膨胀很小,因此有助于瓷坯稳定性的提高。因此莫来石瓷可做为高频装配瓷,化学瓷,热电偶瓷等。莫来石是硅铝酸盐耐火材料的主要矿物组成,莫来石质高铝耐火材料制品中莫来石  相似文献

蛇纹石瓷是镁质瓷的一种。镁质瓷主要系指滑石瓷、堇青石瓷、镁橄榄石瓷、镁铝类尖晶石瓷。由于这类瓷的机械强度很高、并有良好的介电性能,所以工业上被广泛应用于高频瓷器的制造上。这类瓷虽在第二次世界大战时才开始研究,现已成为无线电工业的必需材料。应用镁质瓷制造日用瓷器,近年来我国有几个地方进行了研究,但多采用滑石作为  相似文献

The intention of the present study was to develop an alternative composition for making porcelain material using diopside as the main raw material. Particle size distribution, X‐ray diffraction, X‐ray fluorescence spectrometer, and field emission scanning electron microscope were carried out to characterize the body. Alfa‐quartz, diopside, anorthite, and clinoenstatite were major phases of fired sample. The flexural strength, 131.54 MPa, was two times higher than that of conventional porcelains. During firing, iron ions were diffused into diopside crystal lattice giving the porcelain body a favorable whiteness. It is applicable in preparation of porcelain material using diopside as the main raw material.  相似文献

In order to extend the raw materials base for the production of porcelain, it is suggested to use the local raw material of Siberia, i.e., diopside, which makes it possible to decrease the sintering temperature and to improve the physicochemical properties and whiteness of porcelain. The introduction of over 15% diopside gives rise to a new crystalline phase, i.e., anorthite. This decreases the sintering range and the viscosity of the melt.Translated from Steklo i Keramika, No. 8, pp. 20–22, August, 1995.  相似文献

Strong fluxes are needed to fire vitrified ceramics at temperatures significantly lower than those usually reached in industrial firing cycles. This work is aimed at understanding the role of strong fluxes in the microstructural evolution during sintering. Six fluxes (colemanite, ulexite, wollastonite, diopside, spodumene and phonolite) were individually added to a porcelain stoneware batch and processed in standard conditions. Compacts and fired bodies were characterized by optical dilatometry, XRD-Rietveld, SEM and measuring technological properties. Strong fluxes change the firing behaviour with a complex interplay of sintering kinetics, microstructural features, and phase composition. Every flux has its own repercussion on the properties of the liquid phase (chemical composition, degree of polymerization, viscosity and surface tension) which are key points to explain the observed microstructure, densification rates, and stability at high temperature. Batches with phonolite, wollastonite or diopside exhibit characteristics closer to standard porcelain stoneware, while spodumene and borates suffer from unsatisfactory microstructures and lower densification efficiency.  相似文献

Ceramic pigments with the structures of diopside and anorthite are obtained from natural wollastonite. It is demonstrated that the reactions of synthesis of diopside structure occur in several stages with formation of intermediate products. Mineralizing additives are required for a more complete phase formation of the anorthite structure. The obtained pigments have a vivid color and can be used to decorate porcelain, faience, and majolica products. Translated from Steklo i Keramika, No. 2, pp. 18 – 20, February, 1999.  相似文献

The possibility of preparing ceramic pigments on the basis of natural silicates is investigated. It is shown that tremolite and diopside rock can be used for obtaining ceramic pigments with the structure of diopside. Wollastonite gives a wollastonite structure which can be the base for preparing diopside and anorthite using additives.  相似文献

A local variety of diopside rock is investigated with a view to using it in ceramic-tile mixtures. Specifics of sintering and phase formation of ceramics are determined for the combination of diopside rock and local clays from Khakassia. A diagram is developed for choosing a tile mixture composition with the required degree of sintering. Properties of various-purpose tiles of optimum compositions are described.
