氧化镧对锰渣陶瓷孔隙率的影响初探

Research on Porosity for Rare Earth Lanthanum Oxide Adding Manganese Slag Ceramics

添加稀土元素氧化镧对锰渣进行试验,按一定配比制作稀土陶瓷,研究了稀土元素对烧成温度的影响。测定在不同温度下样品的吸水率,了解其值的变化规律。通过扫描电镜等分析,提出氧化镧加入锰渣坯体中有结晶,助熔,催化的作用,充分表现出稀土元素的活性。烧制温度的研究对以后稀土陶瓷材料的开发具有一定的指导意义。

Adding rare earth lanthanum oxide to manganese slag,according to a certain proportion to make rare earth ceramics,know the effects of rare earth elements on firing.Determination water absorption of the sample under different temperature,know its value changes.Through scanning electron microscopy analysis,put forward to join the manganese slag lanthanum oxide body crystallization,melting,catalysis,fully demonstrate the activity of rare earth elements.Study on firing temperature of rare earth ceramic materials development has certain guiding significance.
