Extended Data Fig. 3. Characterization of preceramic resins.
a, Thermogravimetric analysis (TGA) shows that after heating SIL 30 resin to 800 °C in nitrogen, 9.5% of the initial mass remains. b, X-ray diffraction patterns show that after pyrolysis of cured SIL30 resin at 800 °C and 1200 °C, the products remain amorphous. After annealing at 1400 °C, the measured pattern has reflections that match those for α-Si3N4 (PDF 04-0070851) from the International Centre for Diffraction Data (ICDD)51,52. c, TGA of HDDA-Ceramic Mix shows that after heating to 800 °C in nitrogen, 8.8% of the initial mass remains. d, X-ray diffraction pattern showing that after pyrolysis of the HDDA-Ceramic mix at 1400 °C for a total of 8 h, the measured patterns has reflections that match those for α-Si3N4 (PDF 04-0070851) and SiO2 (PDF 04-0075018) from the ICDD53.
