    Microstructure and Thermal Conductivity of Sintered Reaction-Bonded Silicon Nitride: The Particle Size Effects of MgO Additive by Shin-Il Go, Yinsheng Li, Jae-Woong Ko, Ha-Neul Kim, Se-Hun Kwon, Hai-Doo Kim, Young-Jo Park

    Published 2018-01-01
    “…It was revealed that the size of MgO is critical for thermal conductivity with regard to the microstructural evolution process. That is, the abnormal grain growth promoted by an inhomogeneous liquid-phase distribution led to higher thermal conductivity when coarser MgO was added, whereas a relatively homogeneous liquid-phase distribution induced moderate grain growth and lower thermal conductivity when finer MgO was added.…”
