Abstract: A fluidic module includes a monolithic closed-porosity ceramic body that has a first region and a second region with the first region disposed between the second region. The first and second regions are configured to differ from one another with respect to a common attribute of a ceramic material of the ceramic body. The common attribute can differ by forming the first and second regions from ceramic particles that differ with respect their particle sizes. The fluidic module further includes a tortuous fluid passage that extends through the ceramic body. The fluid passage is surrounded by the first region such that the fluid passage is separated entirely from the second region at least within a planar region of the ceramic body. The fluid passage has an interior surface with a surface roughness of less than or equal to 5 ?m Ra. A method for forming the fluidic module is disclosed.

Abstract: A device and a process for forming a monolithic substantially closed-porosity ceramic fluidic device having a tortuous fluid passage extending through the device, the tortuous fluid passage having a smooth interior surface, a material of the ceramic body having a continuous and uniform distribution of grains at least between opposed major surfaces of the ceramic body. The process includes positioning a positive fluid passage mold within a volume of binder-coated ceramic powder, pressing the volume of ceramic powder with the mold inside to form a pressed body, heating the pressed body to remove the mold, and sintering the pressed body. A relationship between a first stability characteristic of the volume of ceramic powder and a second stability characteristic of the mold prevents discontinuities in the pressed body after pressing and/or during heating.

Abstract: A process for forming a fluidic module (150) with integrated fluid separation includes positioning a first positive passage mold (115A) of a first fluid passage (170) having a tortuous shape within a volume of binder-coated ceramic powder (110A) and positioning a second positive passage mold (115B) of a second fluid passage (175) having a tortuous shape within the volume of ceramic powder (110A) and spaced apart from the first positive passage mold (115A). The process further includes positioning a powder interconnect (120) adjacent to a portion of each of the first (115A) and second positive passage molds (115B) within the volume of ceramic powder (110A), pressing the volume of ceramic powder (110A, HOB) with the first and second positive passage molds (115A, 115B) and the powder interconnect (120) inside to form a pressed body (148), heating the pressed body to remove the first and second positive passage molds (115A, 115B), and sintering the pressed body (148) to form a closed-porosity ceramic body (150).

Abstract: A module and process for forming a ceramic fluidic module (300) that includes a unified closed-porosity ceramic body (200) and a tortuous fluid passage (P) that extends through the body (200). The body (200) has a first mean density within a first layer (222) that is greater than a second mean density within a second layer (226). The first and second layers (222, 226) are axially serially arranged between opposed major surfaces (228, 229) of the body (200). The fluid passage (P) adjoins the first layer (222) of the body (200). The process includes pressing a first volume of ceramic powder (120) to form a pre-pressed body (150). A passage mold (130) is then positioned on the pre-pressed body (150). The pre-pressed body (150) and the passage mold (130) are then covered with a second volume of ceramic powder (125). The body (150), the mold (130), and the second volume of ceramic powder (125) are then pressed to form a pressed body (160).
