Ceramic inks based on preceramic polymers were developed for inkjet printing with an office bubble jet printer. The base system consists of a water-crosslinkable silicone polymer, a latent water source for in situ water generation, and a tin catalyst. While the silicone polymer and the water source can be mixed in any proportion, the catalyst must be added separately to achieve crosslinking at room temperature within minutes. By pyrolysis in inert atmosphere at 1000°C the system was shown to have a high ceramic yield exceeding 50 wt. %. The base system is compatible with alkanes, which makes it suitable for particulate filler, which can be used to control viscosity and tailor properties.
