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。These rapid changes in surface temperature and other weather parameters could lead to severe mismatches between regional conditions and the physiological requirements of many plant species
