| Abstract |
| In line with ACCs stride towards new materials, the
Research & Consultancy Directorate of the company has
successfully developed and scaled up the process for
manufacture of high and ultra high purity alumina
powders at semi-commercial levels for high performance,
structural and electronic applications.
Among the various applications of high purity alumina
powders, wear resistant parts and thermal barrier coatings
are of prime importance for the domestic market. In order
to optimise the powder characteristics for wear resistant
applications, a study was undertaken to evaluate the influence
of various parameters such as chemical purity, phase
com~osition, ~article size distribut~on, specific ~urfa.ce area
(RE1) of startmg powders and their effect on smtermg and
wear properties. The paper highlights the influence of powder
characteristics on sintering and wear resistance properties
of the fabricated grinding media during milling. |
