摘要: A ceramic precursor, prepared by condensation reaction from poly(vinyl alcohol) (PVA) and boric acid (H3BO3) in 1:1, 2:1 4:1 molar ratios, was synthesized as low temperature synthesis route for boron nitride ceramic. Samples were pyrolyzed at 850°C nitrogen atmosphere followed characterization using Fourier transform infrared spectroscopy (FTIR) X-ray diffraction (XRD).
