Abstract
Procedimiento para preparar un fosfato de aluminio-metal alcalino, cuyo procedimiento comprende las etapas de: a) poner en contacto un ácido fosfórico de calidad alimenticia, que tiene una concentración de 70 a 90% en peso de H3PO4 aproximadamente, con una cantidad suficiente de un ión de metal alcalino elegido entre sodio, potasio y mezclas de los mismos e ión aluminio, para formar cristales de un fosfato de aluminio-metal alcalino en una lechada y b) secar y granular dicho fosfato de aluminio-metal alcalino caracterizado porque comprende las etapas de: 1) poner en contacto la lechada de fosfato de aluminio-metal alcalino con un compuesto de calcio después de la formación inicial de cristales de fosfato de alumino-metal alcalino en la lechada y antes de completarse el secado de la etapa b) y 2) granular dicho producto, mientras se seca, bajo tales condiciones que la mayoría de las partículas granuladas secas sean inferiores a unas 840 micras y al menos el 90% sean inferiores a 2.000 micras, teniendo las partículas granuladas de fosfato de aluminio-metal alcalino una superficie exterior que contiene calcio.
