Metakaolin is a kind of active aluminosilicate mineral material produced by calcinate kaolin clay at700 ℃. 偏高岭土是高岭土经700℃煅烧得到的活性铝硅酸盐矿场材料。
When calcinate temperature below 700 ℃, the iron oxide crystal was not integrity and the color was light; 煅烧温度低于700℃,氧化铁晶相不纯,颜色较浅;
And the continuous and discontinuous calcinate manners have different influences on the structure of the sample. 间断焙烧与连续焙烧这两种方式对制备出的产物晶型有不同的影响。
Effect of Calcinate Temperature on Properties of Ferric Oxide Dye from Iron Mud Through Dry Process 煅烧温度对铁泥干法制备氧化铁颜料性能的影响
The effect of preparation conditions such as calcinate temperature, calcinate time and the amount of La3+ were studied. 研究了制备催化剂时焙烧温度、焙烧时间和La3+掺杂量对催化剂活性的影响。
The results show that the calcined kaolin has been transformed from crystallized kaolin to non-crystal one, and calcinate temperature has some influence on its structure. 实验结果表明:煅烧产物由煅烧前的晶态转变成了非晶态,煅烧温度对煅烧产物的结构有一定影响。
The results showed that calcinate temperature was an important factor in the preparation process of iron oxide. 结果表明煅烧温度是干法制备氧化铁颜料的一个重要因素。
By high-temperature calcinate, the fabric fiber ( nylon) was successfully removed, and the ZnO hollow tube-like structures were obtained. 2. 通过高温煅烧可除掉织物纤维(尼龙),得到ZnO中空管状分级结构。
