摘要: Some examples of the use CRTA method for synthesis materials with controlled texture and structure are given. BaTiO 3 has been obtained from thermal decomposition Barium Titanyl Oxalate (BTO) Citrate (BTC) by controlling reaction temperature in such a way that partial pressure gases generated was maintained constant at value close to 10 -2 mbar. It shown this allows getting crystal sizes considerably lower than those decomposing same precursors conventional methods. This small lead stabilisation metastable cubic phase regards tetragonal phase. also control CO carbothermal reduction silica tailoring composition silicon nitride as final product.
