Direct Ink Writing of SiCN/RuO₂/TiB₂ Composite Ceramic Ink for High-Temperature Thin-Film Sensors.

ABSTRACT: Direct ink writing (DIW) of high-temperature thin-film sensors holds significant potential for monitoring extreme environments. However, existing high-temperature inks face a trade-off between cost and performance. This study proposes a SiCN/RuO₂/TiB₂ composite ceramic ink. The added TiB₂, after annealing in a high-temperature atmospheric environment, forms B₂O₃ glass, which synergizes with the SiO₂ glass phase formed from the SiCN precursor to effectively encapsulate RuO₂ particles. This enhances the film's density and adhesion to the substrate, preventing RuO₂ volatilization at high temperatures. Additionally, the high conductivity of TiB₂ improves the film's overall conductivity. Test resu
