When sufficient sintering has taken place, the ceramic body will no longer break down in water; additional sintering can reduce the porosity of the ceramic, increase the bond area between ceramic particles, and increase the material strength. [5] Industrial procedures to create ceramic objects via sintering of powders generally include: [6]
Simulation of the outside of the Space Shuttle as it heats up to over 1,500 °C (2,730 °F) during re-entry into the Earth's atmosphere Bearing components made from 100% silicon nitride Si 3 N 4 Ceramic bread knife. Ceramic engineering is the science and technology of creating objects from inorganic, non-metallic materials. This is done either ...
Liquid phase sintering is a sintering technique that uses a liquid phase to accelerate the interparticle bonding of the solid phase. In addition to rapid initial particle rearrangement due to capillary forces, mass transport through liquid is generally orders of magnitude faster than through solid, enhancing the diffusional mechanisms that drive densification.

Compaction of ceramic powders is a forming technique for ceramics in which granular ceramic materials are made cohesive through mechanical densification, either by hot or cold pressing. The resulting green part must later be sintered in a kiln. The compaction process permits an efficient production of parts to close tolerances with low drying ...
Primary applications are the reduction of microshrinkage, the consolidation of powder metals, ceramic composites and metal cladding. Hot isostatic pressing is thus also used as part of a sintering (powder metallurgy) process and for fabrication of metal matrix composites, [4] often being used for postprocessing in additive manufacturing.

Porous ceramic membranes are typically manufactured through a slip coating-sintering process. In this process a support is initially made by sintering particles of a ceramic material into a mold with a binding agent. The surface of this support is then coated in a solution of finer ceramic particles and a polymeric binder.
Commercially available equipment for the AM of ceramics mostly relies on layer by layer sintering of powders and is rarely cost-effective. However, the difficulties in machining ceramic articles means that AM techniques can be attractive in situations where production volumes are too low to viably produce molds for slip casting methods.
Ceramic nanoparticle is a type of nanoparticle that is composed of ceramics, which are generally classified as inorganic, heat-resistant, nonmetallic solids that can be made of both metallic and nonmetallic compounds. The material offers unique properties.
