All rights reserved.Nanocrystallines of calcia-stabilized zirconia are known to reveal excellent mechanical and high ionic conductivity properties whose depend on the calcia concentration. In this work, nanocrystallines of calcia-stabilized zirconia were synthesized from zircon precursor and 7.5 weight % CaO at 1000 °C, 1200 °C, and 1400 °C. Phase transformation and microstructure evolution were investigated by an X-ray diffraction and a scanning electron microscopy. Another un-doped zirconia was also synthesized from the local zircon by following the same procedure for comparison. A fully cubic form of the calcia-stabilized zirconia and calcium zirconate were obtained at 1200°C having the crystallite sizes ranging from 55 to 87 nm and remained stable at 1400 °C. Meanwhile, un-doped zirconia consisted of pure the monoclinic zirconia at 1200 °C and 1400 °C. High agglomeration is found in the calcia-stabilized zirconia particles at 1000 °C, whereas grain boundaries and interconnect are observed at 1400 °C. The cubic crystal of zirconia has specific and different finger print characteristics in the infra-red spectrum compared to the monoclinic zirconia.[/vc_column_text][vc_empty_space][vc_separator css=”.vc_custom_1624528584150{padding-top: 25px !important;padding-bottom: 25px !important;}”][vc_empty_space][megatron_heading title=”Author keywords” size=”size-sm” text_align=”text-left”][vc_column_text][/vc_column_text][vc_empty_space][vc_separator css=”.vc_custom_1624528584150{padding-top: 25px !important;padding-bottom: 25px !important;}”][vc_empty_space][megatron_heading title=”Indexed keywords” size=”size-sm” text_align=”text-left”][vc_column_text]7.5 wt% calcia-stabilized zirconia,Phase alteration and microstructure evolution,Slaked lime,Zircon[/vc_column_text][vc_empty_space][vc_separator css=”.vc_custom_1624528584150{padding-top: 25px !important;padding-bottom: 25px !important;}”][vc_empty_space][megatron_heading title=”Funding details” size=”size-sm” text_align=”text-left”][vc_column_text][/vc_column_text][vc_empty_space][vc_separator css=”.vc_custom_1624528584150{padding-top: 25px !important;padding-bottom: 25px !important;}”][vc_empty_space][megatron_heading title=”DOI” size=”size-sm” text_align=”text-left”][vc_column_text][/vc_column_text][/vc_column_inner][vc_column_inner width=”1/4″][vc_column_text]Widget Plumx[/vc_column_text][/vc_column_inner][/vc_row_inner][/vc_column][/vc_row][vc_row][vc_column][vc_separator css=”.vc_custom_1624528584150{padding-top: 25px !important;padding-bottom: 25px !important;}”][/vc_column][/vc_row]
