Patent ID: 8128885

Claim:
A microreactor having: a. a substrate ( 10 , 20 , 80 ) having a first layer ( 11 , 21 , 80 ) of a first ceramic material, the first layer ( 11 , 21 , 80 ) containing (1) at least one first component of a crystalline ceramic material and/or a glass material, the first component defining a matrix, and (2) a second component of an additional crystalline ceramic material situated in the matrix, the second component including crystals and/or crystal agglomerates, b. a cavity structure ( 14 , 24 , 84 ) defined by removal of at least some of the surface areas of the crystals and/or crystal agglomerates of the second component in the first layer ( 11 , 21 , 80 ); c. at least one catalytically active material arranged in and/or on the cavity structure ( 14 , 24 , 84 ).
