Description
Способы рафинировани металлов путем фильтровани их через пористзю перегородку известны и основаны на различии температур плавлени чистого металла и примеси и ограниченной взаимной растворимости их около точки плавлени чистого металла. При этом р д присутствующих примесей находитс в расплавленном металле в виде взвеси металлов примесей или их соединений с основным металлом.Methods for refining metals by filtering them through a porous septum are known and are based on the difference between the melting temperatures of the pure metal and the impurity and their limited mutual solubility near the melting point of the pure metal. In this case, a number of impurities present are in the molten metal as a suspension of impurity metals or their compounds with the base metal.
Насто щее изобретение использует указанный способ дл рафиннровани жидкого галли , при этом фильтром служит фильтрующа поверхность его примесей, задержанных пористой перегородкой. Взвесь примеси предварительно укрупн етс за счет роста центров кристаллпзапии , благодар чередованию нагрева и медленному охлаждению.The present invention uses this method to refinish liquid gallium, and the filter is the filtering surface of its impurities, retained by the porous partition. The suspension of impurities is preliminarily enlarged due to the growth of crystalpium centers, due to the alternation of heating and slow cooling.
Фильтрование через пористую пластинку дает значительное снижение содержани примесей в металлическом галлии: если в исходном металле железа было 0,250%, то после фильтровани его стало 0,00025%, меди соответственно было 0,014%, стало - 0,0005% и т. д.Filtration through a porous plate gives a significant decrease in the content of impurities in metallic gallium: if in the base metal iron was 0.250%, then after filtration it became 0.00025%, copper, respectively, 0.014%, became 0.0005%, etc.
Предмет изобретени Subject invention
Способ очистки галли от примесей фильтрованием через нористую перегородку, отличающийс тем, что расплавленный металл при температуре, близкой к затвердеванию, фильтруют через пористую перегородку , покрытую слоем нерастворимых веществ, взвещенных в галлие , предварительно укрупненных путем повторного нагрева и медленного охлаждени .The method of purification of gallium from impurities by filtration through a dichroic septum, characterized in that the molten metal at a temperature close to solidification, is filtered through a porous septum covered with a layer of insoluble substances found in gallium, previously coarsened by repeated heating and slow cooling.
