I have purchased a white alumina (Aluminum oxide ceramic) plate from Amazone. It is 4.5" x 4.5" in dimention with thickness of about 1 mm. This material is very hard and brittle. I want to cut it by a single cut to get 4.5" x 3" for use in the Peltier based cooling device for rapid, high voltage electrophoresis project. Can any one guide me ?
hi,
You can use a glass cutter to make a straight mark of the required length with it on the alumina sample. After that gently hold the alumina substrate and while applying pressure on the crack line, break it. It is exactly similar to the glass cutting procedure with the glass cutter.

Dear Ramesh,
I have faced the same issue several times, finally the best way to cut the alumina is with abrasive waterjet (AWJ). You might need to adjust (fine tuning) the water jet for the best results (pressure of water, content of sand, type of sand).
Greetings,
Dr. George Peppas
Thanks for sharing your own experience. Do your have any idea about the role and effectiveness of cutting either with laser or plasma ?
