Description
Изобретение относитс к получению неорганических соединений ансшогов природных минералов типа С.ЛЮ.Ц, амфиболов и т.д, , которые могут быть использованы в качестве наполнителей в различных композиционных материалах дл электро- и радиотехники. Известен способ получени порошка синтетического фторамфиболевого асбеста путем кристаллизации из расплава с использованием шихты, составленной из окислов и фторидов CQответствую1цих элементов при высоких температурах с последующим охлаждени ем полученного продукта и его-измель чением. С целью упрощени процесса и улу шени физических, химических и механическиу . свойств конечного продук та, предлагаетс вести процесс при 1450-1550°С с использованием шихты состава, вес.%: 1,8-2,2 XF (х-де X На , Li) 0,5-1,5 MgFa., 5-6 MgO и 78 ,5 SiOj с последующим охлаждением .расплава со скоростью 10 20 С/мин и измельчением полученного продукта диспергированием в воде. Эф.фект улу шени свойств порошка фторал1фиболов го асбеста достигаетс за счет дис- , пергировани поликристал.лического слитка в каком-либо растворителе, например в воде. И р и м е р. Исходные компоненты, например фториды натри , лити и магни , карбонаты натри и лити , окись магни и окись кремни и т.п., в качестве которых используют как химические реактивы, так и технические продукты, суиат и.пи прокаливают. Шихту предлагаемого состава перемешивают , а затем плав т в высокотемпературных печах в графитовых тигл х. Расплав охлаждают со скоростью 1020°С/мин . Поликристаллические слитки , содержащие 70-90% основного продукта - синтетического амфибола типа фторрихтерита (Nag i . ) литиевого протоамфибола (t-i2Mg Sigu,,jF) и 10-20% кристаллизук цегос совместно с амфиболом водонабухающего фторгекторита , обрабатывают в воде. Полученный в результате самопроизвольно-г го диспергировани с.питка порошок отдел ют декантацией или фильтрованием и сушат. В результате диспергировани получают кристаллы амфибола ириной 5-10 мкм и длиной 300-500 мкм.The invention relates to the production of inorganic compounds of natural minerals of the type C. LYU.C, amphiboles, etc., which can be used as fillers in various composite materials for electrical and radio engineering. A method is known for producing a powder of synthetic fluorine-fibrous asbestos by crystallization from the melt using a mixture composed of oxides and fluorides of CQ corresponding to the elements at high temperatures, followed by cooling of the obtained product and its grinding. In order to simplify the process and improve physical, chemical and mechanical. properties of the final product, it is proposed to conduct the process at 1450-1550 ° C using the composition of the mixture, wt.%: 1.8-2.2 XF (xxD Na, Li) 0.5-1.5 MgFa., 5-6 MgO and 78, 5 SiOj, followed by cooling the melt at a rate of 10–20 C / min and grinding the resulting product by dispersion in water. The effect of improving the properties of a powder of fluoroallabic asbestos is achieved by dispersing the polycrystalline ingot in a solvent, for example, in water. And p and meer. The starting components, for example, sodium fluoride, lithium and magnesium fluoride, sodium and lithium carbonates, magnesium oxide and silicon oxide, etc., which are used as chemical reagents and technical products, are suiat ipi calcined. The mixture of the composition according to the invention is stirred and then melted in high temperature furnaces in graphite crucibles. The melt is cooled at a rate of 1020 ° C / min. Polycrystalline ingots containing 70-90% of the main product - synthetic amphibole of the type of fluorichterite (Nag i.) Of lithium protoamphibole (t-i2Mg Sigu ,, jF) and 10-20% of crystalline tsegos together with amphibole of water-swollen fluoro vector, are treated in water. The resulting spontaneous dispersion of the powdered material is separated by decantation or filtration and dried. As a result of dispersion, amphibole crystals of irin 5-10 microns and a length of 300-500 microns are obtained.
