Abstract

FIELD: chemistry.
SUBSTANCE: invention relates to field of silicate technology, namely to compositions of glass, which can be applied for manufacturing products for decorative-artistic purposes. Glass contains, wt %: PbO 50-56; B2O3 12-14; SiO2 20-25; CdO 4-5; NaF 0,5-1; Pr2O3 4-5. Glass melting is realised in electric furnaces at temperature 1300-1350°C. Water resistance of glass constitutes II hydrolytic class.
EFFECT: increase of glass water resistance.

Description

Изобретение относится к области технологии силикатов, а именно к составам стекла, которое может быть использовано для изготовления изделий декоративно-художественного назначения.The invention relates to the field of technology of silicates, namely, compositions of glass, which can be used for the manufacture of decorative and artistic products.

Известно стекло, содержащее, мас.%: PbO 50-75; B2O3 1-10; SiO2 12-25; TiO2 1-8; CdO до 3; NaF до 6 [1].Known glass containing, wt.%: PbO 50-75; B 2 O 3 1-10; SiO 2 12-25; TiO 2 1-8; CdO up to 3; NaF up to 6 [1].

Задача изобретения состоит в повышении водостойкости стекла.The objective of the invention is to increase the water resistance of glass.

Технический результат достигается тем, что стекло, содержащее PbO, B2O3, SiO2, CdO, NaF, дополнительно содержит Pr2O3 при следующем соотношении компонентов, мас.%: PbO 50-56; B2O3 12-14; SiO2 20-25; CdO 4-5; NaF 0,5-1; Pr2O3 4-5.The technical result is achieved in that the glass containing PbO, B 2 O 3 , SiO 2 , CdO, NaF, additionally contains Pr 2 O 3 in the following ratio of components, wt.%: PbO 50-56; B 2 O 3 12-14; SiO 2 20-25; CdO 4-5; NaF 0.5-1; Pr 2 O 3 4-5.

В таблице приведены составы стекла.The table shows the compositions of glass.
