Synthesis of nanometer - sized cerium oxide and its effect on catalyzing decomposition of absorbent powder 纳米氧化铈的制备及其催化性能研究
Three series of absorbent powder samples were synthesized by the high - temperature solid - state method : the first is that fe / ti mol proportion in the material changes regularly ; the other one is that different thuliums doped in the same absorbent ; the last series is the absorbent was doped by different content thulium . the permittivity and permeability of the modified ilmenite absorbents were systematically measured 通过使原料中金属离子的摩尔比例( fe ti )作有规律变化、在同一基质中掺杂同含量的不同稀土金属以及改变同种稀土金属的掺杂量等手段,采用高温固相合成法制备了不同系列可供进行吸波性能研究的钛酸亚铁类化合物吸收剂。
