ceramicsthrough

Ceramicsthrough is a coined term used in some design and materials communities to describe ceramics that incorporate deliberate through-structural features, such as through-holes, channels, or through-thickness conduits, in a single component. It is not a standard term in established literature; rather, it refers to a family of concepts that overlaps with porous ceramics, through-porous membranes, and structurally integrated ceramics.

Design and properties: Through-structures enable transport, interconnectivity, or load transfer, and are often used to improve function without external assemblies. Materials commonly used include alumina, silicon carbide, silicon nitride, zirconia, and cordierite. Designers must account for sintering-induced shrinkage, pore-by-pore distribution, and the risk of crack initiation around through features.

Manufacturing methods: Methods include slip casting, tape casting, extrusion, and ceramic additive manufacturing (3D printing) such as binder jetting or vat photopolymerization. Post-processing includes debinding, sintering at appropriate temperatures, and surface finishing or glazing. Achieving precise through features often requires design compensation and process calibration.

Applications: Potential applications cover filtration and separation membranes with through-pores, catalytic supports and reactors with through-channels for flow distribution, thermal insulation with through passages, and porous ceramic scaffolds for biomedical implants or tissue engineering where through pores promote integration.

Challenges and outlook: Key challenges include controlling pore size and distribution around through structures, maintaining mechanical strength and toughness, and scaling production for consistent quality. Ongoing research focuses on advanced processing, multi-material integration, and using through-structures to enhance performance in high-temperature or corrosive environments.
