Abstract :Barium metaborate insert ignore into journalissuearticles values(BaO.B2O3 /BaB2O4); is a very often used additive that uses in dyes, plactics, textile, rubber, glue industry and for protection of wood meterials but it doesn’t produce in Turkey. β-barium metaborate crystal, the low-temperature phase of barium metaborate, is a non-linear optical crystal which has perfect properties. In this experimental study, microwave assisted synthesis was examined to produce barium metaborate for the first time. The experiments were carried out by microwave power level in 270W, 360W and 600W with 1,2,3,4 and 5 min. reaction times. The effects of microwave power level and reaction times changes on the production yield were determined. The 86% production yield was reached in reaction conditions of 360W and 3 min. After the heat treatment in 620 °C, the powder which has the same crystal phase with β- BaB2O4 was produced.
Keywords : β BaB2O4, boric acid, microwave assisted synthesis, microwave power, production yield
