Principales aplicaciones<\/h3>\n

Agricultura:<\/strong> Su principal campo de aplicaci\u00f3n es la producci\u00f3n de fertilizantes fosfatados, como el superfosfato, el superfosfato triple y el fosfato am\u00f3nico, que aportan a los cultivos los nutrientes esenciales de f\u00f3sforo.<\/p>\n

Sector alimentario:<\/strong> El \u00e1cido fosf\u00f3rico de calidad alimentaria act\u00faa como regulador de la acidez, potenciador del sabor y conservante en bebidas (por ejemplo, refrescos de cola), mermeladas y embutidos; adem\u00e1s, regula el pH de los productos alimenticios.<\/p>\n

Fabricaci\u00f3n industrial:<\/strong> Se utiliza en el tratamiento de superficies met\u00e1licas (fosfataci\u00f3n) para formar una pel\u00edcula protectora de fosfato sobre las superficies de acero, lo que evita la corrosi\u00f3n; sirve como materia prima para sales de fosfato (por ejemplo, fosfato de sodio, fosfato de potasio) y detergentes; y se emplea en la producci\u00f3n de cer\u00e1mica, vidrio y productos electr\u00f3nicos.<\/p>\n

Tratamiento del agua:<\/strong> Se utiliza como inhibidor de incrustaciones y de la corrosi\u00f3n en sistemas industriales de agua de refrigeraci\u00f3n, evitando la formaci\u00f3n de incrustaciones de calcio y magnesio.<\/p>\n

Productos farmac\u00e9uticos:<\/strong> Se utiliza en la s\u00edntesis de determinados medicamentos y como regulador del pH en formulaciones farmac\u00e9uticas.<\/p>","protected":false},"excerpt":{"rendered":"
