| Use | In 1955, the National Reed Company of the United States used the flame melting method to make an artificial gem without a natural counterpart. Its chemical composition is srtio3. equiaxed crystal system. Colorless. Refractive index n = 2.409. Dispersion 0.190. Relative density 5.13. Hardness 5~6. No cleaway, the fracture shell-like. No fluorescence under ultraviolet light. This artificial gem is often cut and ground into emerald type, which is a very good diamond substitute. Strontium titanate (Sr Ti O3) has a typical perovskite structure and is a widely used electronic functional ceramic material. It has the advantages of high dielectric constant, low dielectric loss and good thermal stability, and is widely used in electronic, mechanical and ceramic industries. At the same time, as a functional material, strontium titanate has a forbidden band width |

titanate, strontium - Preparation Method
Open Data Verified Data
with strontium carbonate and titanium dioxide as raw materials. Strontium carbonate, titanium dioxide and other additives in an amount of the same substance are mixed and ground, extruded, put into an electric furnace, and calcined at 1100 to 1200 ° C. For 2.5 to 3 hours. The calcined material was pulverized, then ground, pickled, filtered, washed, and dried to obtain strontium titanate. Or strontium chloride, titanium tetrachloride, oxalic acid as raw materials, the reaction to obtain a white precipitate, filtered, washed with deionized water to no chloride ion, then anhydrous ethanol washing dispersion, dehydration, drying at 700 deg C, it can be calcined at 800 °c.
