Abstract

Настоящее изобретение предлагает экономичный способ изготовления губчатого титанового материала высокой чистоты, содержащего меньшие количества кислорода и металлических элементов. Для этого при производстве губчатого титанового материала способом Кролла время t вакуумного разделения на стадии вакуумного разделения устанавливают как t=t+(15~35) ч, где t- это время от начала вакуумного разделения до момента времени, когда температура Tцентральной части материала в реакторе достигает стабильной температуры. В центральной части материала и вблизи нее, где количества металлических элементов являются небольшими, измеренная по методу БЭТ удельная площадь поверхности составляет менее 0,05 м/г.Международная заявка была опубликована вместе с отчетом о международном поиске.The present invention provides an economical method of manufacturing a sponge titanium material of high purity, containing smaller amounts of oxygen and metal elements. To do this, in the production of a titanium sponge material by the Kroll method, the vacuum separation time t at the vacuum separation stage is set as t = t + (15 ~ 35) h, where t is the time from the start of vacuum separation to the time when the temperature T of the central part of the material in the reactor stable temperature. In the central part of the material and near it, where the quantities of metal elements are small, the specific surface area measured by the BET method is less than 0.05 m / g. The international application was published together with an international search report.
