|solidification point/crystallization point;結晶溫度
結晶溫度(Crystallization Temperature)是指物質從液态或熔融态轉變為固态晶體時的特定溫度範圍。該參數反映了物質内部原子、分子或離子有序排列形成晶格結構的熱力學條件,是材料科學、化學和地質學等領域的關鍵指标。
材料科學領域
在金屬加工中,結晶溫度決定合金冷卻過程中晶核形成與晶體生長的速率,直接影響材料的機械性能和微觀結構。例如,鋼的退火工藝需精确控制結晶溫度以優化晶粒尺寸(參考:ASM International《金屬手冊》)。高分子材料的結晶溫度則影響塑料制品的透明度與強度,如聚丙烯(PP)的結晶溫度區間為120℃–140℃(來源:《高分子材料科學與工程》期刊)。
化學工業應用
溶液結晶過程中,溫度控制可分離提純化合物。例如,蔗糖從糖漿中析出的結晶溫度與溶液飽和度直接相關,該原理被廣泛應用于制糖工藝(引用:美國化學會《工業化學工程基礎》)。
地質學意義
岩漿冷卻時,不同礦物的結晶溫度差異導緻火成岩的分層結構。橄榄石在約1200℃時率先結晶,而石英則在600℃–700℃形成,這一序列稱為鮑文反應系列(來源:美國地質調查局USGS火山學研究報告)。
結晶溫度(crystallization temperature)是指物質在特定條件下從液态或非晶态轉變為晶态的溫度。以下是詳細解釋:
結晶溫度是材料在冷卻或加熱過程中開始形成晶體結構的臨界溫度。例如,熔融金屬冷卻時,達到該溫度後會逐漸形成晶體。對于高分子材料,這一溫度可能表現為冷結晶溫度(cold crystallization temperature),即非晶态材料在加熱時重新結晶的溫度。
