Abstrakt: Ceramics and semiconducting materials with internal channels are crucial in a variety of diverse technologies such as "lab on a chip," fuel cell applications, and cooling of microelectronics. In this paper, techniques for fabricating internal channels in brittle materials first are reviewed. Then, the mechanical machining of surface channels in 99.99% pure alumina partially sintered at 600°C and 700°C is discussed. After machining, the partially sintered alumina is sintered to a density of about 97% of theoretical and then joined to 96% pure alumina to convert the surface channels into internal channels.
