UPPER GLAZE LAYER COMPOSITION FOR SANITARY EARTHENWARE, AND SANITARY EARTHENWARE
To provide an upper glaze layer composition for sanitary earthenware capable of reducing the number of surface defects of a sanitary earthenware, and the sanitary earthenware.SOLUTION: There is provided an upper glaze layer composition for sanitary earthenware, which is a slurry with a glaze raw material dispersed in water, and in which a second melting temperature measured by the following measurement method 1-1 is 850 to 1150°C. A DTA curve is calculated by using an alumina powder as a reference material, and a dried article of the upper glaze layer composition for sanitary earthenware as a test powder, a temperature of the reference material at a first inflection point where potential difference ΔV exhibiting a value ΔT by reducing a temperature of the reference material from a temperature of the sample powder in a range of over 700°C of the DTA curve becomes small is set as a first melting temperature, and a temperature of the reference material at a first inflection point where the potential difference ΔV in a range of a higher temperature side than the first melting temperature becomes large is set as the second melting temperature.SELECTED DRAWING: None
【課題】衛生陶器の表面欠点の数を減らすことができる衛生陶器用の上釉層組成物及び衛生陶器。【解決手段】釉原料が水に分散されたスラリーであり、下記測定方法１−１で測定される第二溶融温度が８５０〜１１５０℃である、衛生陶器用の上釉層組成物。＜測定方法１−１＞アルミナ粉末を基準物質とし、衛生陶器用の上釉層組成物の乾燥物を試料粉末としてＤＴＡ曲線を求め、前記ＤＴＡ曲線の７００℃超の領域において、前記試料粉末の温度から前記基準物質の温度を減じた値ΔＴを示す電位差ΔＶが、小さくなる最初の変曲点における前記基準物質の温度を第一溶融温度とし、前記第一溶融温度よりも高温側の領域において、前記電位差ΔＶが、大きくなる最初の変曲点における前記基準物質の温度を第二溶融温度とする。【選択図】なし
