Description
ве в течение 30 мин, по мере образсжани I шпинели расплав загустевает. При этом происходит реакци : . . Г M9Cl2-KC1 2KAlCl4 20a- ; riqAl204 3KCl: iCl2 ; Количество выдел ющегос хлора определ ют титр сжанием 5%-ного раствора йодисто:го кали . Расход кислс зода составл ет 112 л/час. Полученный продукт трехкратно ; промывают от солей кали водой, отфильт : рсжывают и осадсж просушивают при 12О Выход шпинели составл ет 96-97% вес. % от расчетного. : Полученна шпинель - кристаллический : порошок белсго цвета, ик еет размер кристаллов 2-3 микрона с октаэдрической фор ; мой зерен, показатель светопреломлени ; N ср 1,718 и чистота 10-4%, ( р, ,f Химический состав Мд А1 О : содержа:ние - 71,84%, Mgt) 28,22%. Предмет изобретени 1. Шихта дл адюмомагниевой шпинели, включающа соли алюмини и магни , о тличающа с тем, что, с целью получени тонкодисперсной шпинели высо кой чистоты при одновременнсш снижении энергетических затрат и стоимости, а также упрощени процесса, она содержит в качестве солей алюмини и магни хлоралюминат кали и карналлит обезвоженный при следующем соотношении указанных компоненте, вес. .%: Хлоралюминат кали 6О-70 Карналлит обезвоженныйЗО-40 2. Способ изготовлени шпинели из шихты по п. 1, отличающийс тем, что плавление шихты осуществл ют при температуре 800-9ОО°С, а в расплав подают газообразный килород в количестве л/час на ГОО грамм исходной шихты.ve for 30 minutes, as the spinel I is formed, the melt thickens. When this occurs, the reaction is:. . G M9Cl2-KC1 2KAlCl4 20a-; riqAl204 3KCl: iCl2; The amount of chlorine released is determined by squeezing a 5% solution of iodide: potassium iodide. The flow rate of the acid plant is 112 l / h. The resulting product is tripled; washed from potassium salts with water, filtering off: pszhuyut and precipitates are dried at 12 o. The output of spinel is 96-97% by weight. % of the calculated. : The resulting spinel is crystalline: a powder of Belsgo color, it has a crystal size of 2-3 microns with an octahedral form; my grains, light refraction index; N cf 1.718 and purity 10–4%, (p,, f Chemical composition Md A1 O: containing: ing - 71.84%, Mgt) 28.22%. The subject matter of the invention 1. The mixture for adyomomagnesium spinel, including aluminum and magnesium salts, is such that, in order to obtain high purity fine spinel while reducing energy costs and costs, as well as simplifying the process, it contains aluminum and magnesium potassium chloraluminate and carnallite dehydrated in the following ratio of these components, wt. .%: Potassium chloraluminate 6O-70 Carnallite dehydrated RZ 40. The method for making spinel from a batch according to claim 1, characterized in that the melting of the batch is carried out at a temperature of 800-9OO ° C, and gaseous gas hydrogen is supplied to the melt hour on go of grams of the initial charge.
