K20, A1203, BaO, Li20 with possible fining additives, especially Sb2Oa and F2. The most commonly used for the production of TV picture tubes are glasses in which the chemical composition per 1000 parts by weight includes six basic components, mainly 820 to 690 parts ¬ sci Si02, 60 to 150 parts of Na20, 35 to 75 parts of K20, less than 30 parts of A1203, less than 140 parts of BaO and less than 6 parts of Li20, with possible clarifying additives, especially up to 15 parts of Sb203, up to 5 parts of As203 and / or up to 30 parts F2. There is also a glass for the production of television picture tubes produced at a ratio of weight per 1000 parts of mass mainly from four components including 760 to 700 parts of SiOz, 50 to 100 parts of Na20, more than 75 parts of K20 and 60 to 150 parts of BaO, with possible clarifying additives in the form of Sb203, F2 and possibly other impurities. The aim of the invention is to lower the forming temperature T3 corresponding to a viscosity of 10 * loams at a constant value of the coefficient of 10 15 20 25 thermal expansion, which has a value of about 92-10-7— ° .K This solution contributes to the reduction of thermal energy consumption for glass production and extends the service life of the washing equipment At high temperatures. The essence of the invention "consists in the fact that the glass mass intended for the production of TV picture tubes is composed in weight ratios into 1000 parts of the three essential components 790 to 690 SiO 2, 100 to 180 parts Na20 and 50 up to 160 parts of BaO, with the possible addition of up to 15 parts of fining agents, especially Sb203, and impurities up to 30 parts, especially Fe203, A1203, K20 and / or F2.C An example is given below to illustrate the invention. 77.8 parts by weight of SiO2, 6.7 parts by weight of BaO, and 15.5 parts by weight of Na20 mixed to obtain a glass that has a common thermal expansion factor of 92.84 * 10-7— ° and a K forming temperature T3 of approximately 1254 ° C Whereas the four-component glass, containing 73.17 parts v. Si02, 10.61 pts. v. BaO, 7.53 pcs. v. Na2O and -8.7 pts. v. K20, has a coefficient of thermal expansion of '92.84-10-7 .- °, forming temperature 121 489) 3 121 489 4 T3 = 1290 ° C and in almost the entire range for this value of the coefficient of thermal expansion is constant. From the above data it follows that the glass according to the invention has a forming temperature T3 lower by 36 ° C than the temperature of the known glass, which is extremely important in the production of glass mass. Patent claim Glass used for the production of TV cathode-ray tubes, containing fining agents, characterized by the fact that it consists of in parts by weight 5 per 1000 parts of glass with 790 to 690 parts of Si02, 100 to 180 parts of Na20 and 50 to 160 parts of BaO.ZGK, Oddz. 2 Chorzów, residing in 6697-83 - 110 copies Price PLN 100, - PL
