calcine

The precursor method could solve the problem that the appearance of pyrochlore phase during the synthesis procedure by avoiding the direct reaction between pbo and nb _ ( 2 ) o _ ( 5 ) . furthermore it also could decrease calcination temperature and pbo volatility 采用二次合成法制備pmn - pt鈣鈦礦相,避免了pbo和nb _ 2o _ 5的直接反應,從而抑制了焦綠石相的生成。

While this concept for calcination / carbonation processes sounds simple , in practice sorbents undergoing cyclic calcination and carbonation suffer from a serious loss of calcium utilization efficiency as the cycling proceeds 雖然煅燒/碳化過程的原理聽起來似乎簡單,但實際上,在循環煅燒和碳化的過程中,吸附劑的鈣使用效率將嚴重下降。

It can be seen from this study that avoiding a hardened and impervious lump formed in calcination can accelerate al extraction from coarse metakaolin pellets , and a high leaching rate can be reached within a batch process 該研究結果表明,避免高嶺土球粒在煅燒時被“燒死” ,能使粗粒煅燒高嶺土的酸溶反應易于進行。

When the calcinations temperature fell into the scope of 300 - 400 , its resistance begun to decrease sharply . however , the resistance almost kept unchanged under higher calcinations temperature 電阻值隨熱處理溫度的升高而下降,在300 ? 400左右時,電阻值下降很快,繼續升高熱處理溫度,電阻值減小趨勢變緩。

The lowest temperature of formation of the proveskite phase in sol - gel derivede pst thin film is approximately 500 c by rtp , which is 50 c lower than that by relatively long and constant calcinations 約在500已開始形成晶相,相應要降低約50 。在600下的晶相含量比同溫度下保溫熱處理薄膜增加約14 。

During charging from the conveyor belts or vibrating feeders . the circular shaft design facilitates uniform stone and fuel distribution during charging and calcination throughout the complete shaft cross section 圓形窯的設計使在整個窯筒的橫截面上上料和煅燒過程中的石料和燃料的分配更加均勻。

With increasing calcination temperature , the photocatalytic activity of the tio2 thin films gradually increased due to the improvement of crystallization of the anatase tio2 thin films 隨熱處理溫度的升高,薄膜的光催化活性逐漸增加,這是由于薄膜中銳鈦礦相tio _ 2的形成和tio _ 2晶化程度的提高。

The results showed that sequence and way of feeding , reaction temperature , time of aging , stirring speed and drying and calcinations had remarkable influence on the pore structure 結果表明,加料順序、加料方式、成膠溫度、老化時間、攪拌速率以及干燥焙燒等因素對孔結構均有明顯影響。

In order to account for the various effects of active reduction water in a theoretical way we have consistently pursued various calcination methods for special mineral ores 為了研究活性還原水的諸多效果的原理,我們一貫追求特殊礦石的燒成方法,終于成功達到前所未有的諸多效果。

Differential scanning calorimetry ( dsc ) was applied to explore the calcinations parameters , including temperature raising and decreasing rate , holing temperature and time 采用dsc對原料進行了差熱分析,確定合適的升溫速率、降溫速率、保溫溫度及保溫時間等煅燒條件。
