Title:
MANUFACTURE OF METALLIC TI
Document Type and Number:
Japanese Patent JPH03150327
Kind Code:
A
Abstract:

PURPOSE: To continuously and efficiently manufacture the high purity metallic Ti by sticking and forming metallic Ti on the surface of metallic Ti grains in a reactor by each gaseous body of titanium halide and Mg, fluidizing the metallic Ti grains in an another reactor and removing impurities.

CONSTITUTION: Fine-grained metallic Ti is charged onto a dispersion plate 2 at the bottom of a reactor 1, and from the lower direction of the dispersion plate 2, each steam of TiCl4 and Mg as well as an Ar gas heated by a plasma heater 4 are blown in to form a fluidized bed, and metallic Ti formed by a reducing reaction is stuck and accumulated on the surface of the metallic Ti grains. The metallic Ti grains which have grown in the reactor 1 are continuously introduced into a reactor 5 for refluidizing treatment, in which an Ar gas heated to about 1300 to 1400°C by a plasma heater 6 is blown from the lower direction of a dispersion plate 11 to dry away MgCl4, Mg, etc., sticking the metallic Ti grains in a fluidized state and MgCl4, Mg, etc., contaminated on the inside. Next, the metallic Ti grains in the reactor 5 are sent to a classifier 7 and are classified into the metallic Ti grains of fine grains and the ones having prescribed grain size or above, and the fine grains are returned into the reactor 1.
