“…The sol-gel process is an attractive synthetic approach to produce silicon oxycarbide glasses, as revealed by a number of studies published in this field. [170][171][172] The sol-gel technique can be applied for the synthesis of SiAlCO-precursors as well.…”

“…Because of their structure, SiOC glasses have tailorable physical properties that strongly depend on the microstructure (presence of phase separation and bonding state of carbon) and composition (carbon content). They exhibit remarkable mechanical properties, including high elastic modulus, bending strength and hardness; resistance to oxidation at high temperature, devitrification and creep; and chemical durability superior to conventional silicate glasses in aggressive environments (Eguchi & Zank 1998;Pantano et al 1999). In particular, they have been shown to possess a variable propensity to contact activate coagulation of whole human blood plasma, depending on the carbon/ oxygen ratio at their surface.…”

We have developed a robust technique to fabricate monodispersed solid and porous ceramic particles and capsules from single and double emulsion drops composed of silsesquioxane preceramic polymer. A microcapillary microfluidic device was used to generate the monodispersed drops. In this device, two round capillaries are aligned facing each other inside a square capillary. Three fluids are needed to generate the double emulsions. The inner fluid, which flows through the input capillary, and the middle fluid, which flows through the void space between the square and inner fluid capillaries, form a coaxial co-flow in a direction that is opposite to the flow of the outer fluid. As the three fluids are forced through the exit capillary, the inner and middle fluids break into monodispersed double emulsion drops in a single-step process, at rates of up to 2000 drops s 21. Once the drops are generated, the silsesquioxane is cross-linked in solution and the cross-linked particles are dried and pyrolysed in an inert atmosphere to form oxycarbide glass particles. Particles with diameters ranging from 30 to 180 mm, shell thicknesses ranging from 10 to 50 mm and shell pore diameters ranging from 1 to 10 mm were easily prepared by changing fluid flow rates, device dimensions and fluid composition. The produced particles and capsules can be used in their polymeric state or pyrolysed to ceramic. This technique can be extended to other preceramic polymers and can be used to generate unique core -shell multimaterial particles.

“…This synthesis was adapted from that described by Pantano et al [15]. Two equivalents (eq) of triethoxysilane (TREOS, Fluorochem), 1 eq of methyldimethoxysilane (MDMS, Fluorochem), and 4 eq of ethanol as a solvent were added to a Teflon reaction vessel.…”

Silicon oxycarbide glass has been investigated as a potential immobilisation medium for irradiated graphite waste from nuclear power generation. The glass was synthesised via sol-gel techniques using alkoxysilane precursors. Attempts to produce a wasteform via conventional sintering were unsuccessful, but dense wasteforms were achieved by spark plasma sintering (SPS). Microstructural investigations showed that the addition of graphite to the glass did not alter the structure of the matrix; no reaction between the graphite and the glass matrix was observed. Silicon oxycarbide glass is a viable candidate for encapsulation of graphite waste prior to disposal.
