Korean J. Met. Mater. 2021;59(10):753-759.   Published online 2021 Sep 6
DOI: https://doi.org/10.3365/KJMM.2021.59.10.753

Abstract
A porous ZrFe alloy specimen was prepared as a 6 × 3 mm (diameter × thickness) disk. The reaction of the ZrFe alloy was confirmed while the whole system was maintained at a target temperature, which was increased from 150 oC to 950 oC in a 99.999% low purity nitrogen.....

Korean J. Met. Mater. 2020;58(7):501-506.   Published online 2020 Jul 5
DOI: https://doi.org/10.3365/KJMM.2020.58.7.501

Abstract
The properties and H2O adsorption characteristics of two types of zeolites (3A and 13X) with the same shape but different element composition were identified. These zeolites are used in gas purification processes to manufacture 9N ultra-pure inert gases for semiconductor process applications. To analyze the shape and microstructure of the.....

노윤영, 김광배, 송오성
Korean J. Met. Mater. 2017;55(1):39-45.   Published online 2017 Jan 5
DOI: https://doi.org/10.3365/KJMM.2017.55.1.39

Abstract
Cobalt silicide was used as a counter electrode to replace the Pt catalytic layer of a dye-sensitized solar cell (DSSC) device. 100 nm Si/ 100 nm Co on quartz was formed by sputtering and cobalt-silicides were formed by vacuum heat treatment at 500 ℃ and 700 ℃ for 30 min,..... More

Korean J. Met. Mater. 2016;54(8):615-620.   Published online 2016 Aug 5
DOI: https://doi.org/10.3365/KJMM.2016.54.8.615

Abstract
Nickel silicide was used as a counter electrode to replace the Pt catalytic layer of a dye-sensitized solar cell (DSSC) device. 50 nm Si/ 50 nm Ni was formed on glass or quartz by sputtering, and nickel silicides were formed by vacuum heat treatments at 450 and 800 ℃ for..... More
