微波磁場燒結的不但降低燒結溫度,縮短燒結時間,而且使磁體整體加熱,受熱更均勻,因而磁體晶粒更細小,並且主相晶粒邊界趨于規則化,晶間相的分佈更均勻;在常規燒結的磁體中則出現了晶粒異常長大現象,造成這一現象的原因,一方面可能是燒結溫度過高或燒結時間過長,另一方面可能是磨製的粉體均勻性較差,存在的大顆粒被許多細小顆粒包圍,在燒結過程中,大顆粒不斷吞併小顆粒,逐漸長大,而異常長大的晶粒自然會導致磁體性能的惡化。Abstract : based on the ahievement of epitaxial growth in several perovskite oxide films, we discuss the importance of substrate temperature ( ts ) and substrate material in the epitaxial growth of perovskite oxide thin films. influences of ts on growth orientation and epitaxial threshold temperature were observed. the results indicate that during the growth of the oxide films the phase formation and growth dynamics should be taken into consideration. the threshold temperature for epitaxial growth depends on the substrate materials. this demonstrates the influence of substrate material on the initial nucleation and epitaxial growth
