 Method of producing wollastonite ceramic pigments based on dicalcium silicates / 2498967
Method involves fast water cooling of a gel calcined at 1050-1100°C, said gel being obtained by concentrated hydrochloric acid treatment of a mixture of finely ground wastes - dicalcium silicate (nephelene sludge) (63.0-70.4 wt %), silicon oxide (22.0-24.6 wt %) and chromophore (5.0-15.0 wt % with respect to the oxide). Obtained pigments are stable in the 650-850°C temperature range and can be used to produce overglaze paints and low-melting glazes.
Brick glaze / 2498966
Brick glaze contains the following, pts.wt: clay 1-2; chalk 1-2; yellow lead 30-36; pyrolusite1-2; zircon 20-26; potash 6-8. A glaze suspension with moisture content of 45-47% is prepared. The suspension is deposited in form of a thin layer on the surface of the formed brick, which is dried to moisture content of 2-5%, dried and sent for firing at temperature of 950-1050°C.
Method of producing protective-decorative coatings on wall ceramic articles / 2498965
Method of producing protective-decorative coatings on wall ceramic articles involves depositing on the front surface of a ceramic article a slurry of quartz sand, which is finely ground using superplasticiser MB-1 in amount of 0.8-1.0%, plasma melting of said front surface with a plasma jet lying horizontal to the front surface at a distance of 5-8 mm. The plasmatron has operating power of 9.5 kW and the plasma jet moves on the front surface at a speed of 0.30 m/s. Quality of the finished articles is inspected after treatment with the plasma jet.
Engobe / 2495005
Invention relates to engobed ceramic construction materials. The engobe contains the following components, wt %: white-burning clay - 54.0-58.0; quartz sand - 5.0-7.0; scrap glass - 10.0-14.0; ferrochrome slag - 25.0-27.0.

FIELD: chemistry.
SUBSTANCE: brick glaze contains the following components, pts.wt: clay 6-8; chalk 2-4; yellow lead 30-34; pyrolusite 6-8; quartz sand 44-52; potash 2-4.
EFFECT: high frost resistance of the brick glaze.
1 tbl
The invention relates to the construction materials industry and relates to compositions of glazes for use on ceramic brick.
Famous brick glaze containing parts: clay 100; chalk 10; lead litharge 57; pyrolusite 8 [1].
The objective of the invention is to increase the frost resistance of brick glaze.
The technical result is achieved by the fact that brick glaze, including clay, chalk, lead litharge, pyrolusite, additionally contains quartz sand and potash in the following ratio of components, parts: clay 6-8; chalk 2-4; lead litharge 30-34; pyrolusite 6-8; quartz sand 44-52; potash 2-4.
The glaze was obtained as follows.
Prepare and dispense components, such as any selected from the table structure.
