It exhibits an excellent improvement in electrical conductance and dielectric constant. With the loading mass fraction of 3%& 10%, the resistivity of resulting composite decreases by 3 orders of magnitude with respect to unaligned composite. 在添加质量分数为3%~10%的镍纳米颗粒时,导电率提高了3个数量级,介电常数增大了2~3倍。
With the increasing mass rate of phosphoric acid and iron powder, the resistivity is obviously improved. 不同磷酸包覆铁粉电阻率的研究比较,伴随磷酸与铁粉质量比的增加,磁粉芯的电阻有明显地提高。
