氫氧化鈣如何轉化為氧化鈣 - 行業資訊 - 臨沂江聯環?？萍加邢薰?/title> <meta name="keywords" content=" " /> <meta name="description" content=" 兩種物質之間是可以相互變換身份的，當然這樣的情況一般發生在兩者相似的情況下，氫氧化鈣和氧化鈣之間就可以完成這樣的轉化，當然轉化也是有條件的?！　a(OH)2加熱脫水變成CaO，Ca(OH)2=CaO+H2O 條件是：加熱(△)，這是因為難溶性的堿加熱易分解。先和二氧化碳生成碳酸鈣，再煅燒碳酸鈣就可。其實直接煅燒氫氧化鈣就可以得到氧化鈣，但這樣的實驗條件較高，而且產物不很純。氧化鈣變身成氫氧化鈣也是可以的，CaO..." /> <link rel="shortcut icon" href="/favicon.ico" /> <link
