Purpose -The purpose of this paper is to synthesize anticorrosion pigments of the perovskite type, YXO 3 , where X ϭ Ti, Zr, Mn or Al and Y ϭ Ca, Sr, La or Fe, for coating materials intended for corrosion protection of metals. Also, to synthesize pigments containing hexavalent Mo and W (double perovskites). Design/methodology/approach -The anticorrosion pigments were synthesized from oxides or carbonates by a high-temperature process. The following pigments were synthesized: CaTiO . The pigments were characterized by the physico-chemical properties of the powders, by X-ray diffraction analysis and by scanning electron microscopy. Epoxy-ester coating materials containing the pigments at a volume concentration PVC ϭ 10 per cent were prepared and subjected to tests examining their physico-mechanical properties and tests in simulated corrosion atmospheres. Findings -The perovskite structure was identified in the majority of the pigments. The pigments were found to impart good corrosion inhibiting properties to coating materials. The highest calculated anticorrosion efficiency was found for paints containing CaMnO 3 or SrMnO 3 as the pigments. Practical implications -The pigments synthesized can be used with advantage in paints intended for corrosion protection of the substrate metals. Originality/value -The use of the above pigments in anticorrosion coating materials to protect metals is new. Especially beneficial are the uses and procedures for the synthesis of anticorrosion pigments which do not contain heavy metals and are acceptable from the environmental protection aspect.

“…These pigments are heat stable to temperatures exceeding 1000°C and they are suitable for a majority of applications [3]. They have been widely used as a semiconductor in dye-sensitized solar cell [4], catalysts [5], electrodes in electrochemical double layer capacitors (EDLC) [6], solid oxide fuel cells (SOFCs) [7], resistors [8], gas sensors [9], transparent optical device [10], and pigments [11].…”

“…It provides indirect evidence that the temperature of the 3D glass matrix embedded in the carbon powder gradually increases from top to bottom during sintering. It has been proved that in an oxidising atmosphere, as the iron content and the temperature change, the colors of the glaze will appear to be instable colors because of the changes of ionic valence (Kar et al , 2008). For the blue region analysed, Co was always present in a small amount, which was sufficient to obtain dark tones.…”

Purpose The low-temperature sintering of silica glass combined with additive manufacturing (AM) technology has brought a revolutionary change in glass manufacturing. This study aims to carry out in an attempt to achieve precious manufacturing of silicate glassy matrix through the method of slurry extrusion. Design/methodology/approach A low-cost slurry extrusion modelling technology is used to extrude silicate glassy matrix inks, composed of silicate glass powder with different amounts of additives. Extrudability of the inks, their printability window and the featuring curves of silicate glassy matrix are investigated. In addition, the properties of the low-temperature sintering green part as a functional part are explored and evaluated from morphology, hardness and colour. Findings The results showed that the particle size was mainly distributed from 1.4 µm to 5.3 µm, showing better slurry stability and print continuity. The parameters were set to 8 mm/s, 80% and 0.4 mm, respectively, to achieve better forming of three-dimensional (3D) samples. Besides, the organic binder removal step was concentrated on 200°C–300°C and 590°C–650°C was the fusion bonding temperature of the powder. The hardness values of 10 test samples ranged from 588 HL to 613 HL, which met the requirements of hard stones with super-strong mechanical strength. In addition, the mutual penetration of elements caused by temperature changes may lead to a colourful appearance. Originality/value The custom continuous AM technology enables the fabrication of a glass matrix with 3D structural features. The precise positioning technology of the glass matrix is expected to be applied more widely in functional parts.
