Syed,
A couple suggestions for you, but first you need to specify whether you want
96% alumina or 99%, or something else. Since you are going to put a
glaze/glass layer, or a sputtered layer, on the substrate it probably
doesn't matter too much, however. Depends on what you intend to do with it.
There are a couple ways to go about this. One - go to a company like
LaserAge out of Chicago, or Ahne Oosterhof [who frequents this forum] works
at a laser shop out in CA, I believe. Go to these folks [that generally
have 96% plates in stock ranging up to possibly 6 x 6" in dimension with
thicknesses of approx 0.3mm, 0.6mm, +] and have them either cut the
'wafers', or leave them in the square format with break-away tabs. This
provides different options, depending on who you can find to metalize them
for you.
There are a number of thin film deposition houses out there. Other
questions include do you want a glazed surface - glass frit applied and
reflowed? Or do you want a sputtered SiO2 layer? How thick? [for each
layer]. If going with a glazed approach, there will be a meniscus at the
edge - generally. Depending on how thick you make it.
I would find your deposition source first. Getting the substrate cut will
be the easy part.

Subject: [TN] need alumina wafers
Dear TechNet Denizens,
We are in need of 5 ea. 100 mm alumina wafers. To add to that it would be
beneficial if someone could quote us 5 100 mm alumina wafers with a SiO2
layer, TiO2 layer followed by a Pt layer. If you are able to accomplish
this please email back and contact us. It will also help if sources can be
referenced.
Thank you for your help.
