| The types of raw material required for making alumina ceramics
suitable for the electronic industry are discussed in brief along with
their methods of manufacture. Different fabrication processes for
forming these ceramics are reviewed. These include, electrophoretic
coating, dry pressing, isostatic pressing, extrusion, slip casting, injection
moulding, tape casting and the processes for multilayer structures.
Emphasis is given to the last two processes, which are the most recent
ones, exclusively developed to cater to the needs of the electronic
ceramic industry. The different finishing operations and firing processes
for these ceramics are reviewed. The future growth potential for
this technology and its current status in the country are discussed. |
