中文摘要 | 本研究以不同粒度碳化矽(SiC)、棕剛玉(α-Al2O3)為主成分,並添加各種添加劑,以粉末冶金方式加壓後,前者於1450~1650℃、後者於1350~1500℃燒結形成磨石試樣。試樣經由密度測試及抗滲水性試驗,以了解不同粒度主成分含量、燒結溫度、添加劑等對視密度及抗滲水性的影響。 實驗結果顯示,含90wt%碳化矽(粒度14#:150#:350#重量比值為2:1:2)之主成分中,添加不同比例之Al2O3、Y2O3添加劑,於1475℃燒結2小時,皆可得高視密度及抗滲水性之試樣。 另外,主成分棕剛玉重量(wt%)佔80%(粒度14#:150#=50wt%:30wt%)之試樣,添加15wt%鉀長石、3wt%石英、2wt%油土,於1425~1475℃之間燒結45min.,亦可獲得高視密度及良好之抗滲水性。 |
英文摘要 | In this study, we select silicon carbide (SiC) 、brown alumina (α-Al2O3) of different particle sizes as main content of grindstone specimens, also adding some kinds of additives. The grindstone specimens were formed by press-forming and sintered at different sintering temperatures. The apparent density measurement and anti-water permeation test will be carried out to reveal the effect of main content (wt%) of different particle sizes、sintering temperatures 、additives on apparent density and anti-water permeation of sintered grindstone specimens. The results show the weight ratio of particles size 14#、150#、350# silicon carbide main content is 2:1: 2, if adding different ratio Al2O3, Y2O3 as additives, and sintering at 1475℃for 2hours, we can get the grindstone specimens which have a high apparent density and good anti-water permeation. Also, the specimens which have a main content of an 80 wt %( particles size 14#:150# =50%: 30%)brown alumina, and adding 15wt% potash feldspar (KO2.Al2O3.6SiO2)、3wt% silica powder, 2wt% clay ceram as additives, then sintering at 1425~1475℃ for 45 minutes, we can get the high apparent density and good anti-water permeation specimens too. |
