尖晶石型无钴黑色陶瓷颜料的研究进展

黑色陶瓷颜料目前被广泛应用于陶瓷装饰领域,其传统制备工艺需加入氧化钴,但氧化钴的高价限制了黑色陶瓷颜料的发展,因此开发无钴黑色陶瓷颜料成为陶瓷颜料研究领域的热点之一,而尖晶石型无钴黑色陶瓷颜料因其出色的耐高温性、气氛适应性和化学稳定性受到众多研究者的青睐。本文基于尖晶石型无钴黑色陶瓷颜料的相关研究进展,围绕其呈色机理、制备原料种类和制备工艺等方面进行了详细的阐述与分析。目前,制备该类陶瓷颜料的原料主要分为化工原料、矿物原料和工业固废,制备工艺则主要包括传统高温固相法、微波焙烧法、化学沉淀法、溶胶-凝胶法、微乳液法、溶液燃烧法等,所制备颜料的呈色性能主要受原料组成中过渡金属元素之间摩尔比、焙烧温度和保温时间的影响。相较而言,采用微波焙烧工业固废制备该类陶瓷颜料具有良好的应用前景,但制备过程中尖晶石形成规律和演变机理以及工业固废所引入的杂质组分对颜料性能的影响还有待进一步研究。

Physico-chemical properties of ceramic pigments for high-temperature application

Heat resistant coatings are required primarily for stacks, exhaust pipes, reactors, space crafts and similar equipments that are permanently or occasionally exposed to elevated temperatures.

Production of ceramic pigments with diopside and anorthite structure using the gel method

The possibility of producing ceramic pigments with the diopside and anorthite structures by the sol-gel method using wollastonite is studied. It is established that the use of the gel method intensifies the synthesis of anorthite and diopside crystal structures by means of better homogenization of the batch components at the mixing stage. A positive factor is the effective formation of anorthite and diopside structures at relatively low temperatures (about 1100°C), as well as the mineralizing effect of the chromophores on the crystallization of these minerals. __________ Translated from Steklo i Keramika, No. 8, pp. 26–28, August, 2006.     

Minimisation of toxicity in nickel ferrite black pigment

Abstract

Black ceramic pigments are usually prepared from a mixture of transition metal oxides, including toxic and hazardous elements such as Ni, Co, Cr, and Mn. Spinel type black ceramic pigments based on Ni(Fe,Cr)₂O₄ prepared by a ceramic method have been optimised to reduce toxic and hazardous components. Ni (an A1 carcinogen as classified by ACGIH)has been partially substituted by inert elements such as Mg and Zn and the content of Cr (an A1 carcinogen in hexavalent form) has been minimised, to obtain a black ceramic pigment in which the important properties (colour and stability) are maintained. The black pigments obtained have been glazed and compared with commercial pigments. While maintaining adequate colouring properties, the concentration of toxic elements in the composition has been reduced.     

Ceramic pigments and dyes beyond the inkjet revolution: From technological requirements to constraints in colorant design

The advent of digital decoration has changed the technological requirements of colorants and the way they are applied onto ceramic substrates. This technological revolution has introduced additional steps in colorant production (ink micronization) and new constraints in application (ink-jet printing) that cannot be reproduced in a standard ceramic laboratory, so stretching the distance between academic and industrial research. The goal of this work is to provide an up-to-date picture of ceramic pigments, dyes and effects, with emphasis on their behavior in the current decoration technologies, which are shortly reviewed. Technological performance expected for ceramic colorants and new requirements imposed by digital decoration are discussed in detail. An extensive overview of both industrially used and candidate pigments, dyes and effects is focused on the suitability to different ceramic applications and firing conditions. Finally, lines of future research are outlined and commented.
