一种米黄色微晶玻璃及其制备方法和应用
摘要：
一种米黄色微晶玻璃，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 48‑58％，Al2O3 13‑20％，CaO 7.2‑15.6％，MgO 6‑13％，Na2O和/或K2O 6‑13％，ZnO 0‑2％，TiO2或TiO2+ZrO2 5‑13％，CeO2 0.3‑1.2％，Fe2O3和/或MnO2 0.03‑1.2％。本发明还公开了米黄色微晶玻璃的制备方法及应用，本发明米黄色微晶玻璃不含氟化物，色泽柔和，颜色与天然米黄色花岗岩相近，理化性能优于天然花岗岩。
摘要（英）：

The invention relates to off-white microcrystal glass and belongs to the technical field of microcrystal glass. The off-white microcrystal glass comprises the following raw materials in percentage by weight: 48 to 58 percent of SiO2, 13 to 20 percent of Al2O3, 7.2 to 15.6 percent of CaO, 6 to 13 percent of MgO, 6 to 13 percent of Na2O and/or K2O, 0 to 2 percent of ZnO, 5 to 13 percent of TiO2 or TiO2+ZrO2, 0.3 to 1.2 percent of CeO2 and 0.03 to 1.2 percent of Fe2O3 and/or MnO2. The invention also discloses a preparation method of the off-white microcrystal glass. The off-white microcrystal glass provided by the invention does not contain fluoride and has soft color and luster, the color is similar to that of natural off-white granite, and the physical and chemical properties are more excellent than those of the natural granite.
