Abstract
A process for producing a Ti or Ti alloy product includes exposing particles of pyrophoric Ti metal and Ti alloys to a liquor, gas or vapour that includes a passivation component that forms a passivated protective layer with Ti on surfaces of the particles.

A process for producing a Ti metal or a Ti alloy product comprising the following steps:
- (a) reducing TiCl4 in a fluidised bed reactor (“FBR”) with a Mg reductant and producing Ti metal particles dispersed in a protective MgCl2 matrix,
- (b) removing the protective matrix in a vacuum distillation unit and producing particles of Ti metal or a Ti alloy in situations where other metals such as Al and V are formed in the fluidised bed reactor;
- and
- (c) exposing the particles of the pyrophoric Ti metal or Ti alloys to a liquor, gas or vapour that contains a passivation component that forms a protective passivation layer with Ti on the surface of the particles.
(canceled)
An apparatus for producing a Ti metal and Ti alloy product that comprises a contact unit that is configured to bring into contact particles of pyrophoric Ti metal and Ti alloys and a liquor, gas or vapour that includes a passivation component that can form a protective passivation layer on surfaces of the particles of the pyrophoric Ti metal and Ti alloys.
