摘要
本文研究了杂质对SnO_2纳米晶粒生长的影响。结果表明,掺入Li_2O有利于SnO_2晶粒的生长,NiO对SnO_2晶粒的生长没有明显的影响,Al_2O_3、Cr_2O_3、ZrO_2、Fe_2O_3在800℃以下阻碍SnO_2晶粒的生长;在更高温度时,杂质相结晶,它们将不再阻碍SnO_2晶粒的生长。
The influence of impurities on the growth of nanocrystalline SnO_2 particles was studied.The results indicated that Li_2O helped the growth of SnO_2 particles;NiO has no significant influence;Al_2O_3、Cr_2O_3、ZrO_2、Fe_2O_3 hindered the growth of SnO_2 particles at temperature below 800 ℃,At higher temperature,the impurity phases crystallized,they no longer held back the growth of SnO_2 particles.
