Claims (9)
1. Способ восстановления оксида титана в твердом состоянии в электролизере, который включает в себя анод, катод, образованный, по меньшей мере частично, из оксида титана, и расплавленный электролит, который содержит катионы металла, способного химически восстанавливать катодный оксид титана, включающий в себя работу электролизера при потенциале, который выше потенциала, при котором катионы металла, способного химически восстанавливать катодный оксид титана, осаждаются в виде металла на катоде, в результате чего данный металл химически восстанавливает катодный оксид титана, отличающийся тем, что обновляют электролит и/или изменяют потенциал электролизера на более поздних стадиях работы электролизера с учетом реакций, имеющих место в электролизере, и концентрации кислорода в оксидах титана в электролизере для того, чтобы получить титан (α-Ti) высокой чистоты.
2. Способ по п.1, в котором металл, осажденный на катоде, является растворимым в электролите и может раствориться в электролите и поэтому мигрировать в окрестность катодного оксида титана.
3. Способ по п.1 или 2, в котором электролитом является электролит на основе CaCl2, который содержит СаО в качестве одного из компонентов электролита.
4. Способ по п.3, в котором потенциал электролизера выше потенциала, при котором металлический Са может осаждаться на катоде, т.е. потенциала разложения СаО.
5. Способ по п.3, в котором потенциал электролизера ниже потенциала разложения CaCl2.
6. Способ по п.3, в котором при температуре в интервале 600-1100°С и при графитовом аноде потенциал электролизера находится между 1,3 и 3,5 В.
7. Способ по п.3, в котором электролитом на основе CaCl2 является коммерчески доступный источник CaCl2, такой как дигидрат хлорида кальция, который частично разлагается при нагревании и дает СаО или иным образом включает в себя СаО.
8. Способ по п.3, в котором электролит на основе CaCl2 содержит CaCl2 и СаО, которые вводят по отдельности или предварительно смешивают с образованием электролита.
9. Способ по п.1, в котором анодом является графит или инертный анод.
