摘要：

A combustion synthesis of lithium niobate (LN) squares from activated niobium oxide (Nb2O5.nH(2)O) and Li2CO3 was studied to understand all the chemical reactions involved, and the nucleation and square-growth mechanisms. It was found that first the lithium ions react with the fuel (urea), then niobium ions of Nb2O5.nH(2)O begin a continuous reaction with the fuel to form metal-organic complexes. LN nuclei are formed by the solid-state reaction of Li- and Nb-organic complexes at 430 degrees C. Lithium niobate squares are obtained in the crystallization stage at 700 degrees C, which go on to grow into larger squares at 850 degrees C because of the agglomeration effect.
