Description

Изобретение относится к составам подглазурных керамических пигментов, используемых, преимущественно, для декорирования изделий из фарфора и фаянса.The invention relates to compositions of underglaze ceramic pigments used mainly for decorating porcelain and earthenware products.

Известен керамический пигмент, включающий, мас.%: CaO 9,96-11,96; Ca2O3 51,96-57,96; Sm2O3 32,08-36,08 /1/.Known ceramic pigment, including, wt.%: CaO 9.96-11.96; Ca 2 O 3 51.96-57.96; Sm 2 O 3 32.08-36.08 / 1 /.

Известен керамический пигмент, содержащий, мас.%: CaO 10,09-12,09; Nd2O3 32,29-34,29; Ga2O3 53,62-57,62 /2/.Known ceramic pigment containing, wt.%: CaO 10.09-12.09; Nd 2 O 3 32.29-34.29; Ga 2 O 3 53.62-57.62 / 2 /.

Целью изобретения является повышение показателя преломления пигмента.The aim of the invention is to increase the refractive index of the pigment.

Цель достигается тем, что в состав пигмента, содержащего CaO, Na2O3, Ga2O3, дополнительно вводят GeO2 и PbO, при следующем соотношении компонентов, мас.%: CaO 10,0-12,0; Nd2O3 30,0-34,0; Ga2O3 50,0-52,0; GeO2 2,0-4,0; PbO 2,0-4,0.The goal is achieved in that in the composition of the pigment containing CaO, Na 2 O 3 , Ga 2 O 3 , GeO 2 and PbO are additionally introduced, in the following ratio of components, wt.%: CaO 10.0-12.0; Nd 2 O 3 30.0-34.0; Ga 2 O 3 50.0-52.0; GeO 2 2.0-4.0; PbO 2.0-4.0.

В таблице приведены составы пигмента.The table shows the composition of the pigment.

Компоненты пигмента смешивают с 0,1-0,2% электролита, 8-12% воды, выдерживают при 800°C в течение 0,5 ч. Полученную массу размалывают до остатка не более 0,2% на сетке №005. Пигмент используют по назначению.The pigment components are mixed with 0.1-0.2% electrolyte, 8-12% water, incubated at 800 ° C for 0.5 hours. The resulting mass is ground to a residue of no more than 0.2% on a mesh No. 005. The pigment is used as intended.
