Известно стекло содержащее, мол.%.; SiO 5€-б5, СаО 20-25, FejO 5-20, Who 5-10 Cl J. Известное стекло имеет относител ную магнитную проницаемость 5,6-7,3 точка Кюри (630-645)t5c. Наиболее близким к предлагаемому по технической сущности йл етс ферромагнитное стекло, содержащее. Mac.%s SiOj 36,06-44,35, СаО 2,138 .83, 39,75-40,23, Mn04,448 .84,ВаО 2,15-13,22 t2l. Недбстатком указанного CTfeKrta вл етс невысокое значениз коэрцитивной силы по намагйиченности. Цель изобретени - повьшение зна«1ен коэрцитивной силы по намагниченности. 2 Поставленна цель достигаетс тем, что ферромагнитное стекло, включающее SlO ,СаО, ВаО, МпО, дополнительно содержит при следующем соотношении компонентов , мас.% 36,07-41,38 2,3-11,88 2,24-13,22 4,02-8,85 39,11-40,23 1,0-5,0 Синтез стекол провод т из шихтных материалой марок ч, хч и чда в электрической печи с карборундовыми нагревател ми при температурах, не превышающих 1500°С. ВьГработку стекла осуществл ют в графитовые формы На чугунной плите и вЫФ гиванием в дрот с последуюп1им при 650°С. Интервал формовани определен из температурных зависимостей в зкости. Конкретные составы сфекол и их свойства приведены в табл. 1 и 2 соответственно. .Таблица 1 3 Наличие в стеклах оксидов марганца , бари и железа позвол ет получить структурные единицы ферритов ма ганца и бари в результате обменного взаимодействи катионов железа с катионами марганца и бари . Магнитные моменты обменно св занных пар в матрице стекла хаотически ориентированы как парамагнетики и практичес ки не дают вклада в упор доченную самопроизвольную намагниченность. Коэрцитивна сила обусловлена капельной , составл ющей стекол. Кальциевые бесщелочные стекла характеризуютс обьгчным развитием ликвационных процессов, и при содержании окси дов железа 20 моп.% ликвационна фаза представл ет собой непрерывную двухкаркасную структуру. В натриевых стеклах реализуетс капельна структура. Поэтому при Дос таточном количестве магнитной фазы, котора пропорциональна намагничен 824 ности насьпцени (92,63 и 99,73 кАУм), предлагаемый состав cтekлa обладает повышенным значением коэрцитивной силы (74,95 кА/м). Оптимальным содержанием оксида натри вл етс 2%. Меньшие количества натри не позвол ют получить капельной магнитной структуры стекла, а большие количества привод т к диамагнитному разбавлению обменно-св занных пар, ответственных за остаточную намагниченность материала. Температурный интервал формовани стекла в рабочем диапазоне в зкости 10 -10 Па.с 1023-1383 К. Указанное стекло может быть не .пользовано в качестве штериала АЛЯ производства корей магнитных мешалок , а по величине коэрцитивной силы - дл изготовлени элементов запорной арматуры. Дозирующих устройств и ротаметров контрольноизмерительной техники.This invention relates to glasses with signs of a magnetically hard material, and can be used in chemical technology for mixing aggressive liquids and as a shut-off valve for metering devices and rotameters in the field of instrumentation technology. Known glass containing, mol.%; SiO 5 € -b5, CaO 20-25, FejO 5-20, Who 5-10 Cl J. The known glass has a relative magnetic permeability of 5.6-7.3 Curie point (630-645) t5c. The closest to that proposed by the technical essence was ferromagnetic glass containing. Mac.% S SiOj 36.06-44.35, CaO 2.138 .83, 39.75-40.23, Mn04.448 .84, BaO 2.115-13.22 t2l. The disadvantage of this CTfeKrta is the low value of the coercive force due to magnetization. The purpose of the invention is to increase the sign of the coercive force by magnetization. 2 The goal is achieved by the fact that ferromagnetic glass, including SlO, CaO, BaO, MpO, additionally contains the following ratio of components, wt.% 36.07-41.38 2.3-11.88 2.24-13.22 4.02-8.85 39.11-40.23 1.0-5.0 Synthesis of glasses is carried out from batch materials of brands h, hch and chd in an electric furnace with carborundum heaters at temperatures not exceeding 1500 ° C. Glass processing was carried out in graphite forms. On a cast-iron plate and VYF, a dip was made into a dart, followed by a step at 650 ° C. The molding interval is determined from the temperature dependences of the viscosity. Specific compositions of sphecol and their properties are given in table. 1 and 2 respectively. .Table 1 3 The presence of manganese, barium and iron oxides in glasses makes it possible to obtain structural units of manganese and barium ferrites as a result of the exchange interaction of iron cations with manganese and barium cations. The magnetic moments of exchange coupled pairs in the glass matrix are randomly oriented as paramagnets and practically do not contribute to the ordered spontaneous magnetization. The coercive force is due to the droplet component of the glass. Calcium alkaline-free glasses are characterized by an obstructive development of liquation processes, and with an iron oxide content of 20 mop.%, The liquation phase is a continuous two-frame structure. Drip structure is realized in sodium glasses. Therefore, with a sufficient amount of the magnetic phase, which is proportional to the magnetisation of the nascens (92.63 and 99.73 kAhm), the proposed composition of the glass has an increased value of the coercive force (74.95 kA / m). The optimum content of sodium oxide is 2%. Smaller amounts of sodium do not allow to obtain a droplet magnetic structure of glass, and large quantities lead to diamagnetic dilution of exchange-coupled pairs responsible for the residual magnetization of the material. The temperature interval for forming glass in the working viscosity range is 10 -10 Pa. With 1023-1383 K. The specified glass may not be used as ALA material produced by Korea for magnetic stirrers, but by the magnitude of the coercive force, for the manufacture of shut-off fittings. Dosing devices and rotameters of measuring instruments.
