CERAMIC COMPOSITES

• “Dense and homogenous ceramic material consisting of carbon/silicon nitride nanotubes, production method and applications thereof”. Patent number ES2326018 (B1)🡻

The invention relates to a composite silicon nitride ceramic material consisting of a dense silicon nitride matrix without pores and with non-degraded carbon nanotubes (CNTs) uniformly dispersed inside the matrix. The invention also relates to a method for producing said composite materials by the dispersion of the carbon nanotubes in the silicon nitride matrix and the subsequent spark plasma sintering thereof in a vacuum. Said materials can be used to produce tools, devices or any type of element requiring a good thermomechanical and tribological behaviour, for example, cutting tools or anti-wear components, for example, valves, ball bearings and flanges.

The present invention relates to a silicon nitride ceramic material having a continuous gradient in the microstructural characteristics thereof and in the properties thereof, from one extremity to the other of the ceramic component. Furthermore a method is described for the manufacture in situ of said ceramic materials having a gradient function from a single homogenous composition of ceramic powders and employing a sintering process through electric discharge modifying the temperature profiles within the compacted ceramic powder. These materials may be utilised for the manufacture of tools, devices or any type of element requiring good thermomechanical and tribological performance, for example cutting tools, or in anti-wear components such as valves, bearings and journals. Furthermore they may be employed as substrate wherein exists a porosity gradient wherein to grow nanotubes of carbon and utilise the device as catalyst or membrane.

• “Process for production of graphene/silicon carbide ceramic composites”. Patent number US9988313 (B2)🡻, EP2897921 (B1)🡻, WO2014047283 (A1)🡻

We provide a method for the in situ development of graphene containing silicon carbide (SiC) matrix ceramic composites, and more particularly to the in situ graphene growth within the bulk ceramic through a single-step approach during SiC ceramics densification using an electric current activated/assisted sintering (ECAS) technique. This approach allows processing dense, robust, highly electrical conducting and well dispersed nanocomposites having a percolated graphene network, eliminating the handling of potentially hazardous nanostructures. Graphene/SiC components could be used in technological applications under strong demanding conditions where good electrical, thermal, mechanical and/or tribological properties are required, such as micro and nanoelectromechanical systems (MEMS and NEMS), sensors, actuators, heat exchangers, breaks, components for engines, armours, cutting tools, microturbines or microrotors.
