Abstract

PROCEDIMIENTO PARA PREPARAR FOSFATO DE CALCIO Y SODIO O LITIO CRISTALINO CON FORMA DE AMIANTO. SE JUNTA BAJO CONDICIONES DE REACCION UNA FUENTE DE OXIGENO, CALCIO, FORFORO Y SODIO O LITIO, EN DONDE LAS RELACIONES MOLARES SON APROXIMADAMENTE DE 15 A 30 POR 100 EN MOLES DE OXIDO DE SODIO O LITIO, DE 48 A 60 POR 100 EN MOLES DE P2O5 Y DE 20 A 37 POR 100 EN MOLES DE CAO PARA FORMAR UNA MEZCLA DE SAL FOSFATO. SE MANTIENE LA MEZCLA DE SAL FOSFATO A UNA TEMPERATURA POR DEBAJO DEL PUNTO DE FUSION DEL FOSFATO DE CALCIO Y DEL SODIO O LITIO, DURANTE UN TIEMPO SUFICIENTE PARA FORMAR BLOQUES DE FOSFATO DE CALCIO, Y POR ULTIMO SE DA A LOS BLOQUES LA FORMA DE FIBRA DE CRISTALES ASBESTIFORMES. SE UTILIZAN, MEZCLADOS CON ACEITES COMO LUBRICANTES PARA ALTA TEMPERATURA, COMO AISLANTES TERMICOS, COMO AGENTES DE REFUERZO PARA FIBRAS CELULOSICAS Y PAPELES Y OTROS USOS VARIOS.
