LARGE CERAMIC SHEET
PROBLEM TO BE SOLVED: To provide a thin type large ceramic sheet having suppressed crack and deformation during drying or firing and improved quality change due to variation of firing temperature.SOLUTION: There is provided a large ceramic sheet containing 2 mass% to 20 mass% of Ca element in terms of CaO, 0.1 mass% to 4 mass% of Mg element in terms of MgO, less than 30 mass% of Al element in terms of AlOand Si element and having CaO/MgO, by mass ratio, 5 to 60. In more preferable aspect, there is provided a large ceramic sheet having SiO/CaO, by mass ratio, 3 to 30.
【課題】 乾燥時や焼成時の割れや変形が抑制され、かつ焼成温度の変動による品質変化が抑制された、薄型で大型のセラミック板の提供。【解決手段】 ＣａＯ換算で２質量％以上２０質量％以下のＣａ元素と、ＭｇＯ換算で０．１質量％以上４質量％以下のＭｇ元素と、Ａｌ２Ｏ３換算で３０質量％未満のＡｌ元素と、Ｓｉ元素とを含んでなり、ＣａＯ／ＭｇＯが質量比で５以上６０以下である、大型セラミック板。より好ましい態様によれば、ＳｉＯ２／ＣａＯが質量比で３以上３０以下である大型セラミック板。【選択図】なし
