“…Pigments used in gel polish compositions can be of natural or synthetic origin. Among mineral pigments, the most common materials are of salt and oxide nature, such as iron oxide pigment [2], also spinel-type [3][4][5] and pigments of various silicate structures [6,7]. The inorganic pigments are Pigments to be used for cosmetic purposes must have minimal toxicity.…”

characterized by high color stability but are limited by color palette. Organic pigments have a very rich color palette but are more expensive and are less. The advantages of organic and inorganic pigments can be combined with the synthesis of organic-inorganic materials. The most promising materials of such type are layered double hydroxides (LDH) intercalated with various anions [8], including anionic dyes [9, 10]. The use of LDHs with various cation compositions with different organic anionic dyes would allow broadening the color pallet of pigments, especially for cosmetic applications.

“…The objects of our study are the ceramic pigments, synthesized in the system open-hearth slag-Сr 2 O 3 -NiO (dark brown 1.2d) [17], and open-hearth slag-Сr 2 O 3 -CoO (black 8d) [18]. A temperature range of 1,200-1,250 °С is the most rational for firing such pigments; it enables the formation of the assigned mineralogical composition in combination with Table color indicators.…”

Синтез керамічних пігментів тради ційно здійснюється при високій темпера турі (не нижче 1200 °С). Для її зниження використовують мінералізуючі добавки, які мають різний механізм дії на вихідні компо ненти пігментних шихт. Ефективність дії мінералізаторів визначається їх природою, вмістом, ступенем диспергування в реаген ті, який активується. Отже, пошук най більш ефективних мінералізаторів при син тезі, зокрема, силікатношпінельних кера мічних пігментів має важливе наукове та практичне значення. Досліджено дію різних мінералізуючих добавок (B 2 O 3 , Na 2 B 4 O 7 , Na 2 O, NaF) на про цеси формування кристалофазового складу шлаквмісних керамічних пігментів і зміну їх колірних показників. Встановлена пряма залежність між температурою плавлення мінералізаторів та ефективністю їх впли ву на утворення шпінельних фаз, які висту пають носіями кольору в таких пігментах. Відчутний ефект від введення натрію фто риду, що має найвищу температуру плав лення серед дослідних добавок, досягається в результаті випалу пігментів при темпе ратурі не нижче 1150 °С. Дія натрію окси ду ефективна починаючи з температури 1100 °С. Найбільш доцільно застосовувати борвмісні сполуки. Їх введення дозволяє зни зити температуру випалу шлаквмісних піг ментів до 1050 °С при повному зв'язуван ні вихідних компонентів в шпінельні тверді розчини. Синтезовані при цьому керамічні пігменти забезпечують формування глазур них покриттів, які за якісними показниками не поступаються покриттям, отриманим з додаванням високотемпературних пігмен тів (температура випалу 1200-1250 °С). На утворення силікатних фаз (діопсиду і воластоніту), які не є носіями кольору в дослідних пігментах, ефективну мінералі зуючу дію чинять добавки NaF і B 2 O 3 Ключові слова: керамічні пігменти, міне ралізатори, випал, кристалофазовий склад, колірні показники, глазурні покриття

Purpose The purpose of this paper is to establish physical-chemical patterns and process parameters for obtaining low-temperature pink pigments with the structure of tin sphene using granulated blast-furnace slag. Design/methodology/approach Thermodynamic calculations were made in the work to assess the probability of malayaite phase formation during firing of slag-containing pigments. Mineralogical composition of synthesized pigments was evaluated by X-ray phase analysis. Spectral characteristics of pigments absorption in the infrared region were determined with the use of Fourier IR-spectrometry. Colour characteristics of the developed pigments and glass coatings with their introduction were studied on the comparator colour. Density of ceramic pigments was determined by pycnometric method, and chemical resistance was found on their weight loss after boiling in 1 N hydrochloric acid solution and 1 N sodium hydroxide solution. Findings Peculiar features of formation of the mineralogical composition of pink pigments are studied in the system CaO-MgO-Al2O3-SiO2-SnO2-Cr2O3 with the use of granulated blast-furnace slag. The end product and carrier of the pink colour is the solid solution on the basis of tin sphene. It is established that the most rational concentration of chromium (III) oxide for the formation of pink colouring of the pigments is 2 Wt.%. Practical implications The usage of developed pigments provides obtaining high-quality pink-coloured glaze coatings, in particular for ceramic tiles. Originality/value Activity of the components of blast-furnace slag in combination with the effective mineralizing action of B2O3 additive allows performing the firing of pink of the pigments with the formation of tin sphene at reduced temperature of 1,200°C.
