Description
Предлагаемый способ имеет р д преимуществ по сравнению с прототипом:The proposed method has a number of advantages compared with the prototype:
1. Более высокий выход по току,1. Higher current efficiency,
2. Получение металлов более высокой чистоты.2. Obtaining metals of higher purity.
3. Создание непрерывного и экологически чистого производства.3. Creating a continuous and environmentally friendly production.
4. Широкий круг получаемых металлов и большой выбор соединений из которых их можно восстановить.4. A wide range of metals and a wide selection of compounds from which they can be restored.
5. Высока скорость процесса.5. High speed of the process.
Реализаци процесса показана в примерах .The implementation of the process is shown in the examples.
. Пример 1. В герметичный реактор, содержащий металлический катод (нержавеюща сталь) и нерасходуемый керамический анод, в атмосфере инертного газа (аргона) загружали и наплавл ли хлорид кальци в количестве 3,0 кг. В катодное пространство вводили 0.5 кг двуокиси титана. Субхлорид кальци задавали электролизом. Дл этого включали посто нный ток и вели электролиз при катодной плотности тока 1 А/см1. Example 1. In a sealed reactor containing a metal cathode (stainless steel) and a non-expendable ceramic anode, 3.0 kg of calcium chloride was charged and melted in an atmosphere of inert gas (argon). 0.5 kg of titanium dioxide was introduced into the cathode space. Calcium subchloride was determined by electrolysis. For this, a direct current was turned on and electrolysis was performed at a cathodic current density of 1 A / cm1

Содержание металлического титана в осадке 99,8 %. Выход по току выше 95 %.calcium ions to subions. The calcium subchloride content was maintained at 0.5 May. % The process temperature is 800 ° C. As a result of the experiment, titanium powder was obtained. The content of titanium metal in the sediment is 99.8%. Current efficiency above 95%.
Пример 2. Эквимольные количества металлического кальци и осушенного хлорида смешивали и нагревали до 850° С в атмосфере инертного газа. В результате этой операции получали сплав, содержащий 85-90 % субхлорида кальци . Его загружали в герметичный реактор, содержащий смесь хлорида и фторида кальци и окись титана. Содержание субхлорида поддерживали 20,0 мае. %. Температура процесса 850° С. Содержание металлического титана в полученном осадке 99,87 %.Example 2. Equimolar amounts of calcium metal and dried chloride were mixed and heated to 850 ° C in an inert gas atmosphere. As a result of this operation, an alloy was obtained containing 85-90% calcium subchloride. It was loaded into a sealed reactor containing a mixture of calcium chloride and fluoride and titanium oxide. The subchloride content was maintained on May 20.0. % The temperature of the process is 850 ° C. The content of titanium metal in the obtained precipitate is 99.87%.
Остальные примеры сведены в таблицу. Все опыты проводились в герметичных реакторах в атмосфере инертного газа.Other examples are tabulated. All experiments were carried out in sealed reactors in an inert gas atmosphere.
При ведении электролиза использовали 25 керамические оксидные аноды, на которых выдел етс кислород.In the electrolysis, 25 ceramic oxide anodes were used, on which oxygen was released.
