采用X射线荧光光谱、X射线衍射图谱、紫外可见光吸收光谱等分析方法,对鄂西贡水砚石进行成分、结构的表征,用贮墨实验表征砚石的性能,对砚石开发进行可行性分析。结果表明,鄂西贡水砚石主要矿物成分为白云石、方解石、水云母以及石英。可见光谱吸收峰位于378 nm、437 nm和540 nm附近,分别为Fe3+由6A1g基态到4A1g或4Eg的跃迁、氧八面体中Fe3+的电子跃迁吸收及氧八面体中Fe2+的自旋禁戒跃迁所致。光学显微镜下矿物排列致密,孔隙度极小,多在0.01 mm以下,砚峰密度0.6~0.7个/μm2,砚石类型属于中锋砚石。不同条件下贮墨时长1.3~60.0 h。为鄂西砚石的开发提供科学依据。
X-ray fluorescence spectroscopy, X-ray diffraction and UV-Vis absorption spectroscopy were used to characterize the composition and structure of the Ersi Kenstone. The performance of the inkstone was characterized by the ink storage experiment. The feasibility of the inkstone development was analyzed . The results show that the major mineral components of the inkstone in Western Hubei Province are dolomite, calcite, hydrous mica and quartz. The bands of visible spectra are located at 378 nm, 437 nm and 540 nm, respectively. They are the transition from 6A1g ground state to 4A1g or 4Eg Fe3 + electron transitions in oxygen octahedron and the spin forbidden transitions in oxygen octahedra To Under the optical microscope, the minerals are densely arranged and the porosity is extremely small, mostly less than 0.01 mm, the density of Yanfeng is 0.6-0.7 / μm2, and the inkstone type belongs to the center inkstone. Under different conditions of storage time 1.3 ~ 60.0 h. Provide a scientific basis for the development of West Yan stone.
