詳細說明
 英文名:Magnesium oxide, high purity

 

分子式:MgO

 

分子量:40.30

 

物化性質:高溫下具有優良的耐堿性和電絕緣性。熱膨脹系數和導熱率高。具有良好的光透過性。白色無定形粉末。無臭、無味、無毒。相對密度約3.58(25℃)。熔點2852℃,沸點3600℃.難溶于水,不溶于醇,溶于酸或銨鹽溶液中。經1000℃以上高溫灼燒,可轉化為晶體。溫度升高至1500℃以上時,則成死燒氧化鎂或燒結氧化鎂。遇空氣中二氧化碳生成堿式碳酸鎂。

 

用途:廣泛用作高溫耐熱材料。在陶瓷領域用作透光性陶瓷坩堝、基板等的原料。在電子材料、電氣領域用于磁性裝置填料及各種載體。用作陶瓷基板比氧化鋁熱傳導率高2倍,電解質的損失僅為氧化鋁的1/10。還可作為耐熱性涂料用的填料。

 

制法:純堿法、碳銨法
