Abstract

It has been established that, in the production of titanium powder by the hydration/dehydration route (HDH), there occurs a generation of a significant quantity of fine powders that cannot be used for the manufacture of filters. This project seeks to identify at least two commercial products for the remaining fractions of titanium powder. The proposed approach is the use of the fine fraction of titanium powder for the development of a production route for titanium parts and direct use of the powder for spraying dental implants. The main result of the first phase of the project was the qualification by companies Prodoctor- Implac and De Bortolli, of pilot batches of titanium powder for spraying. Among the activities planned for phase 2 are: the dissemination of the application of titanium powders produced by the HDH route for spraying bone-integrating dental implants; the production of pilot batches for parts; and making viable the use of titanium powders produced by the HDH route for surface treatments (thermic aspersion), among many others. If the proposed lines are established, there will be an increase in foreign exchange earnings, by the simple fact of replacing an import with a material of increased value (titanium powder) or a part manufactured from a sub-product (scrap or titanium residue) at lower cost.
