Growth Mechanism of AlN Synthesized by Directed Nitridation of Molten Aluminium Alloys
铝合金直接氨化生长氮化铝反应机制研究

The growing process of AIN crystal in directed nitridation of molten aluminium alloys was investigated. The growing characters of AIN crystals were obtained through XRD and SEM. A new mechanism of vapour-liquid-solid-solid (VLSS) was proposed, and its similarity and difference from the traditional vapour-liquid-solid (VLS) mechanism were discussed. The emphasis was placed on the prerequisites and realization process of VLSS mechanism.
