Nano-sized Fe_2O_3 crystallites with average grain size of 37.5 nm were synthesized by hydrothermal method. XRD results show that the crystallites belong to rhombohedral system.TEM observation and laser light scattering analysis indicate that the existence of soft-agglomeration for the Fe_2O_3 powder with spherical shape of 100~200nm in diameter. The experimental results show that Fe_2O_3 material has good gas sensing property and long-term stability to alcohol. As the thermal power or the… CONTINUE READING
