A photo-curable liquid composition for additive manufacturing of silicon-containing carbide ceramic includes a polymethylvinylsilane (PMVS) resin that has photo-reactivity over a first photo-wavelength absorption range and a photo-initiator additive mixed with the PMVS resin. The photo-initiator additive has photo-reactivity over a second photo-wavelength absorption range that has an overlapping wavelength range with the first photo-wavelength absorption range. The PMVS and the photo-initiator additive are reactive to polymerize upon exposure to radiation having a wavelength in the overlapping wavelength range.

A polysilazane composition comprising an organopolysilazane compound free of Si—H structure and an organoxysilane compound having at least two silicon atoms in the molecule does not release hazardous substances such as hydrogen or require reactive solvents.

Methods, processes, systems, devices and apparatus are provided for additive manufacture resulting in the 3D printing of ceramic materials and components with a thickness greater than three millimeters (3 mm). A sulfur-free 3D printable formulation comprises a liquid inorganic polymer resin using Stereolithograpy (SLA) printers and Digital Light Processing (DLP) curing of the polymer resin via the chemical bonding of the materials rather than sintering. Thus, the process has shorter manufacturing intervals, significantly lower energy use and produces larger scale ceramic components having less linear shrinkage, less mass loss and high ceramic yield with no corrosive sulfur compounds present in the ceramic component.

In an embodiment, a flame retardant composition comprises 60 to 95 wt % of a polycarbonate; a polysiloxane comprising a repeat unit of the formula (7); wherein the composition comprises 0.5 to 2 wt % of the repeat unit of the formula (7) of the polysiloxane; wherein the polysiloxane is free of one or both of a vinyl graft and repeat units derived from a vinyl monomer; 9 to 18 wt % of talc; 5 to 15 wt % of a phosphorus containing flame retardant; 0 to 1 wt % of a phosphite stabilizer; and 0.1 to 2 wt % of an anti-drip agent.

The present invention relates to gels and processes for making ceramic nanostructures, ceramic nanostructures made by such processes, and methods of using such ceramic nanostructures. Such process is templated via block copolymer self-assembly but does not require any post processing thermal and/or solvent annealing steps. As a result, such process is significantly more efficient and scalable than other processes that are templated via block copolymer self-assembly and yields a ceramic having a pore structure/shape that provides the ceramic with a higher ductility than traditional ceramics.

The present invention relates to an oxidation-stable silver paste comprising silver nanoparticles, and to the use of a paste of this type for the production of decoration elements having a metallic luster on articles having an outer silicate surface, such as porcelain, ceramic, bone china, glass or enamel, to metallic coatings on such substrates and to a process for the production of coatings of this type.
