Description
Effects of CaO and Si02 additives on the sintering phenomena of SrO⋅6Fe2O3 powder were clarified through investigating dependence of density, electrical specific resistivity and microstructure on sintering temperatures. In the case of densification of SrO⋅6Fe2O3 with no additives, unfavourable grain growth occured due to the solid-phase sintering. On the other hand, rapid densification as well as inhibition of grain growth was achieved by the addition of CaO and SiO2, where the liquid phase appeared above 1373K. Electrical specific resistivity of SrO⋅6Fe2O3 spec-imens varied, corresponding to the sintering stage. Especially, the value of electrical specific resistivity decreased sensitively in accordance with temperature range for the appearance of liquid phase formed from CaO-SiO2-SrO⋅6Fe2O3 system. SiO2 add-itive content against CaO had also remarkable influences on the value of electrical specific resistivity and microstructure of sintered SrO⋅6Fe2O3.
