一种青灰色微晶玻璃及其制备方法和应用
摘要：
一种青灰色微晶玻璃，属于微晶玻璃的技术领域，按重量百分比计，包括以下原料：SiO2 32‑44％，Al2O3 28‑38％，CaO 7.2‑15.6％，MgO 6‑13％，Na2O和/或K2O 6‑13％，ZnO 0‑2％，TiO2或TiO2+ZrO2 5‑13％，以及着色剂，所述着色剂为CeO2 2‑2.5％或由CeO2 1.2‑2％、Fe2O3 0.05‑0.2％组成的混合物。本发明还公开了青灰色微晶玻璃的制备方法及应用，本发明青灰色微晶玻璃不含氟化物，色泽柔和，颜色与天然青灰色花岗岩相近，理化性能优于天然花岗岩。
摘要（英）：

Cinerous glass ceramic belongs to the technical field of glass ceramics and comprises the following raw materials by weight percent: 32-44% of SiO2, 28-38% of Al2O3, 7.2-15.6% of CaO, 6-13% of MgO, 6-13% of Na2O and/or K2O, 0-2% of ZnO, 5-13% of TiO2 or TiO2+ZrO2, and a colorant, wherein the colorant is 2-2.5% of CeO2 or a mixture of 1.2-2% of CeO2 and 0.05-0.2% of Fe2O3. The invention also discloses a preparation method and application of cinerous glass ceramic. The cinerous glass ceramic does not contain fluorides, is soft in color, and has the color approximate to that of natural cinerous granite and the physical and chemical properties superior to that of natural granite.
