[Chemical composition] anorthoclase sodium feldspar high temperature and high potassium feldspar isomorphic Ab series of products richer component Ab molecules containing more than 63%, while the content of CaO with Na / K ratio is increased There is a tendency to increase; when it is close to pure Ab, it can contain about 3% to 4% of CaO. [Crystal structure] triclinic system; [Form] The shape of celsian feldspar is as long as feldspar (Fig. G-51); however, some stencils such as feldspar {110}, {201} are particularly developed. Microscopically, the lattice twin crystals are formed by the combination of sodium feldspar law and Xiao Na feldspar law. Figure G-51 æª feldspar crystal [Physical properties] The color, luster, cleavage and hardness of celsian are similar to those of feldspar. The relative density is between 2.56 and 2.62. [genesis and morphogenesis] æª feldspar and æª feldspar feldspar are also similar to feldspar, only found in medium-acid and alkaline volcanic rocks, as plaque or matrix. [Identification characteristics] æª feldspar is different from feldspar and translucent stone by its lattice twin crystal. It differs from micro plagioclase in the characteristics of its lattice twin crystal. [Main use] See the overview of the Changshi people.
Measuring Wheel is also known as measure wheel.There are two types, mechanical and digital display measuring wheel. It is designed for outdoor distance measurement. It can be for a variety of ground conditions, including hills, meadows, and rugged construction sites and so on.

a 0 = 0.82 nm, b 0 = 1.28 nm, c 0 = 0.71 nm; β = 116 °; Z = 4. The crystal structure is the same as the feldspar, the order degree is extremely low, and it is stable under high temperature. Ordragonite or translucent feldspar containing Or in between 25% and 60% can be dissolved into feldspar feldspar or feldspar feldspar.
