A method of manufacturing a microfluid mixer includes pouring a ceramic precursor into a first mold, a second mold and a third mold. The first mold forms a base plate, the second mold forms a top plate, and the third mold forms a first plate. The ceramic precursors are gelled in the first mold, the second mold and the third mold to form a green base plate, a green top plate and a green first plate. The plates are removed from the respective molds. The green base plate, the green top plate, and the green first plate are co-fired to form a ceramic base plate, a ceramic top plate and a ceramic first plate. The ceramic base plate is interlocked with the ceramic top plate and the ceramic first plate, and a diaphragm is disposed upon one of the first plate and the top plate.

1. A method of manufacturing a microfluid mixer comprising: pouring a ceramic precursor into a first mold, a second mold, and a third mold, the first mold having a shape of a base plate; the second mold having a shape of a top plate; the third mold having a shape of a first plate;gelling the ceramic
1. A method of manufacturing a microfluid mixer comprising: pouring a ceramic precursor into a first mold, a second mold, and a third mold, the first mold having a shape of a base plate; the second mold having a shape of a top plate; the third mold having a shape of a first plate;gelling the ceramic precursors in the first mold, the second mold and the third mold to form a green base plate, a green top plate and a green first plate;removing the green base plate, the green top plate and the green first plate from the respective molds;co-firing the green base plate, the green top plate and the green first plate to form a ceramic base plate, a ceramic top plate and a ceramic first plate, the ceramic first plate including a plurality of ports for an entry of a first fluid and a second fluid, a mixing chamber fluidly connected with the plurality of ports;interlocking the ceramic base plate with the ceramic top plate and/or the ceramic first plate; anddisposing a diaphragm upon one of the first plate and the top plate. 2. The method of claim 1, wherein interlocking the ceramic base plate with the ceramic top plate and the ceramic first plate comprises co-sintering the ceramic base plate with the ceramic top plate and the ceramic first plate. 3. The method of claim 1, further comprising: forming at least one heating element cavity in the third mold. 4. The method claim 3, further comprising: mounting a heating element in the at least one heating element cavity. 5. The method of claim 1, further comprising: performing a finishing of the green first plate to form the plurality of ports and at least one channel. 6. The method of claim 5, wherein forming the plurality of ports and the at least one channel includes machining the plurality of ports and the at least one channel into the green first plate. 7. The method of claim 6, wherein machining the plurality of ports and at least one channel includes employing at least one of a electro-discharge machining, ultrasonic machining, micro-ultrasonic machining, abrasive flow machining, electrochemical machining, micro-electrochemical machining, and water jet machining. 8. The method of claim 5, wherein performing the finishing operation occurs after co-firing the green base plate, the green top plate and the green first plate forming the ceramic base plate, ceramic top plate and ceramic first plate. 9. The method of claim 5, wherein performing the finishing operation includes removing rough edges from one or more of the green base plate, the green top plate and the green first plate. 10. The method of claim 5, further comprising: coating the one of the green base plate, the green top plate and the green first plate after finishing. 11. The method of claim 10, wherein coating the one of the green base plate, the green top plate and the green first plate forms one of a wetting surface and a non-wetting surface. 12. The method of claim 10, wherein coating the one of the green base plate, the green top plate and the green first plate includes applying one of a polytetrafluoroethylene and a polydimethylsiloxane to a surface of the one of the green base plate, the green top plate and the green first plate. 13. The method of claim 10, wherein coating the one of the green base plate, the green top plate and the green first plate includes applying a silane coupling agent to a surface of the one of the green base plate, the green top plate and the green first plate. 14. The method of claim 1, further comprising: positioning the ceramic base plate, the ceramic top plate and the ceramic first plate in a trough. 15. The method of claim 14, further comprising: positioning a heating element in thermal contact with the trough.
