溶劑熱法制備的二氧化鈦納米顆粒用不用煅燒？
看文獻(xiàn)照做的，原文部分是這樣的It was kept under vigorous stirring for one hour and the whole mixture was transferred in a 120 ml Teflonlined stainless steel autoclave maintained at 150 ◦C for 18 h and finally cooled to room temperature naturally. This produced a yellowish white colored product which was centrifuged with DI water
and absolute ethanol for several times. Then the sample was dried at 80 ◦C for 3 h. Finally, the powder was collected and grinded in a mortar and pestle for 1 min to obtain fine powder which was used for further investigation
幫我看看應(yīng)該是不用再高溫煅燒了吧？

上面文獻(xiàn)里面說不用煅燒了。用溶劑熱法制備的二氧化鈦，一般都有結(jié)晶性，所以大部分情況下，都不用再燒。
神啊我昨天又燒了一遍尿素，拿錫紙包著了，一點東西沒有，，，
奇怪了，你看一下坩堝是否漏水？要不換個廠家的尿素看看，我試過阿拉丁，國藥，北化的尿素，實驗重復(fù)性都很好。按理說，600度之下都能燒出來，只有高于600度，才全部燒沒。爐子溫度沒啥問題吧。
木有啊我的尿素，，，額九三年的庫房找的，，，爐子應(yīng)該沒問題，我換了兩個爐子燒了
，
換尿素把，可能是尿素的問題。
