“…The exothermic peaks near 200°C likely correspond to further crosslinking of precursors 66 . In these samples, the initiation of polymer to ceramic conversion may be indicated by the exothermic DSC peak near 400°C 67 . Durazane‐1800 displays the highest crosslinking temperature (∼300°C) and lowest ceramic yield relative to the cross‐linked precursor (∼75.8 wt%).…”

This study presents new experimental data on the thermodynamic stability of SiC(O) and SCN(O) ceramics derived from the pyrolysis of polymeric precursors: SMP‐10 (polycarbosilane), PSZ‐20 (polysilazane), and Durazane‐1800 (polysilazane) at 1200°C. There are close similarities in the structure of the polysilazanes, but they differ in crosslinking temperature. High‐resolution X‐ray photoelectron spectroscopy shows notable differences in the microstructure of all polymer‐derived ceramics (PDCs). The enthalpies of formation (∆H°f, elem) of SiC(O) (from SMP‐10), SCN(O) (from PSZ‐20), and SCN(O) (from Durazane‐1800) are −20 ± 4.63, −78.55 ± 2.32, and −85.09 ± 2.18 kJ/mol, respectively. The PDC derived from Durazane‐1800 displays greatest thermodynamic stability. The results point to increased thermodynamic stabilization with addition of nitrogen to the microstructure of PDCs. Thermodynamic analysis suggests increased thermodynamic drive for forming SiCN(O) microstructures with an increase in the relative amount of SiNxC4−x mixed bonds and a decrease in silica. Overall, enthalpies of formation suggest superior stabilizing effect of SiNxC4−x compared to SiOxC4−x mixed bonds. The results indicate systematic stabilization of SiCN(O) structures with decrease in silicon and oxygen content. The destabilization of PDCs resulting from higher silicon content may reach a plateau at higher concentrations.

“…[42] The density and ceramic yield of polymer-derived ceramics can be affected by pyrolysis process parameters and the concentration of curing agent added. [43] The printed structures from 4T and 3T were pyrolyzed in a tube furnace under an argon atmosphere (Figure 3a), with a thermal profile from ambient to 1000 °C at a heating rate of 1 °C min À1 , followed by one-hour isothermal heating at 1000 °C before leaving to cool to room temperature within the furnace. After pyrolysis, the converted black ceramics with shiny surfaces maintained structural integrity, while neither pores nor crack was observed.…”

Additive manufacturing (3D printing) offers new opportunities to create complex structures for many applications. The development of suitable precursors for high‐resolution 3D printing of ceramics is increasingly essential to meet evolving material requirements. Herein, a new hybrid preceramic formulation based on thiol‐ene click chemistry for precision printing of polymer‐derived ceramic has been developed to enable the fabrication of complex 3D objects using high‐resolution projection microstereolithography (PμSL). Two low‐odor thiol compounds with either three (trithiol) or four thiols (tetrathiol) moieties have been examined, to investigate the influence of thiol structure on the mechanical properties of converted ceramics. Pyrolysis of the printed green bodies leads to the formation of silicon oxycarbide (SiOC) with high fidelity after polymer‐to‐ceramic transformation. The SiOC printed specimen converted from the tetrathiol formulation (4T) demonstrates excellent mechanical strength surpassing that of the trithiol‐based formulation (3T) and previously reported SiOC preceramic polymers. The ceramic honeycomb fabricated using the tetrathiol compound shows remarkable improvement in compressive strength, which is two times higher than that of the trithiol‐derived ceramic. This work proposes a simple and effective way to formulate 3D printable preceramic polymers through molecular design. The achieved 3D printed SiOC can fulfill the requirement for high‐strength ceramic materials with complex shapes.
