Abstract

SE PRESENTA UNA FORMA DE CARBONATO DE CALCIO QUE TIENE UN CRISTAL FINAL ROMBOHEDRICO DE BLOQUE DE SEIS CARAS CON UN AREA DE SUPERFICIE DE ENTRE 3 Y 15 M (AL CUADRADO) /G, UNA MEDIA DE TAMAÑO DE PARTICULA DISCRETA DE ENTRE 0.2 Y 0.9 MICRONES, EN DONDE LAS PARTICULAS DISCRETAS TIENEN UNA RELACION DE ASPECTO INFERIOR A 2, Y UNA DISTRIBUCION DE TAMAÑO DE PARTICULA TAL QUE AL MENOS ALREDEDOR DEL 60% DE LAS PARTICULAS CAEN DENTRO DEL 50% DEL DIAMETRO DE LA PARTICULA DISCRETA EQUIVALENTE, EL COMPUESTO ES ADECUADO PARA SU USO COMO MATERIAL DE RELLENO EN LA FABRICACION DE PAPEL PARA MEJORAR LAS PROPIEDADES OPTICAS DEL PAPEL RESULTANTE. TAMBIEN SE PRESENTA UN PROCESO DE ENVEJECIMIENTO ACELERADO MEDIANTE CALOR, QUE UTILIZA TECNICAS HIDROTERMALES, PARA PRODUCIR RAPIDAMENTE ESTA FORMA DE CARBONATO DE CALCIO Y UNA FORMA RELACIONADA DE CARBONATO DE CALCIO QUE TIENE UNA MORFOLOGIA DEL CRISTAL FINAL PRISMATICO EN GRANDES CANTIDADES PARA DAR RESPUESTA A LA DEMANDA DE LA INDUSTRIA DE FABRICACION DE PAPEL COMOUN METODO PARA USAR ESTOS MATERIALES EN LA FABRICACION DE PAPEL.
