Synthesis of a new mechanism of powder and production process

Net, 100% pass rate , the product placed in centrifuge tubes , centrifuged 2rain in the centrifuge , the measured weight and volume , bulk density of products available for the 2.62 × 1km3. Getting the product to 383K removed after 2h oven drying , drying measured reduction of 2.21 %. . Place the product in the muffle furnace roasting 1173K 1h, taken out by a mixture of white and black , prove that the products have been completely decomposed . 2.5 discussion from Figure 2 , Table 1, results analysis, began to yield of the product increases as the temperature rises , when the temperature reaches 973K taken when the high yield , then yield of the product decreased gradually until zero. Therefore, the reaction should be appropriate to 973K temperature. From Figure 3, Table 2, results analysis,[link widoczny dla zalogowanych], with the time . Product yields increased gradually to reach 20min when the reaction time , the product yield reached the maximum , then decreased gradually over 40mill after the reaction time , product yield trend is basically unchanged , therefore, the appropriate reaction time the reaction Should be 20rain. The results from Table 1 and physical characterization results, when the temperature exceeds 1073K , the product will cease to exist , so the decomposition temperature of the product can be drawn should be 1073K. From x. Ray diffraction analysis, the map has sns2 should have all the characteristic peaks should be regarded as sn, but the peak level is not very consistent with the standard value , there is no corresponding standard spectrum analysis is due to the lattice specific . 3 Discussion and Conclusions From the above results the following conclusions can be obtained , the appropriate scale-like formation of tin sulfide temperature 973K, suitable reaction time was 20min, suitable for the production process for the separation of reactants and products, reproducibility of response , the conversion rate of up to 96 .4 %, the product dried reduction of 2.21 %. , bulk density is 262 × lo3kg/m3, product decomposition temperature of 1073K, for a certain product is indeed crystal of sr1S2, the production process without inert gas protection, product for the mica -like material , easily crushed , ground equipment, complete general Can meet the requirements , the product appearance is golden yellow luster powder , the product size of 300 mesh, tin powder raw materials can also be used tin ore.
