Metallizing of Silicon Nitride Ceramics
Journal of the Ceramic Association, Japan, 1986 It was found that a metallized layer can be formed on Si3N4 ceramics using the paste containing Li2MoO4 and TiO2. X-ray diffraction pattern and SEM observations revealed that the metallized layer consisted of Mo, TiN, Y2O3⋅2SiO2, etc., and that the thickness was around 7μm.
