Abstract

Se proporciona un método mejorado para producir tetrahidrato de hexaborato de calcio cristalino, nobleita sintética, mediante la reaccion de ácido borico y cal en una suspension acuosa. Las condiciones de reaccion incluyen relaciones de ácido borico a agua mayores de 0.25:1, relaciones molares de cal a ácido borico en la escala de 0.05-0.15:1 y temperaturas en la escala de 85 degree C a 105 degree C. Se produce un producto cristalino novedoso que tiene un hábito de cristal unico que resulta en propiedades físicas mejoradas. La deshidratacion de este producto produjo un producto anhidro, amorfo, novedoso que tiene hábito de cristal y propiedades físicas similares.
