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。Firstly, the mechanism of the preparation of superfine quartz powder with ball mill is studied in this article, based on nature of quartz material, griffith ' s strength theory and the crush theory of planetary ball mill. the problem of granulation during the process of the preparation of superfine quartz powder is studied minutely. and proposed increasing dispersant and disperser medium to restrain granulation, and dispersing use ultrasonic after milled
