    摘要： The present invention relates to an acid-stabilized calcium carbonate slurry having a pH of less than 7, preferably between about 6 and about 7, containing water, calcium carbonate, preferably precipitated calcium carbonate, and an acid-stabilizer of a water soluble calcium salt, a weak acid, a chelating agent, a weak acid capable of chelating calcium ion, or a mixture thereof. The acid-stabilizer is present in an amount sufficient to provide an aqueous calcium carbonate slurry having an increased calcium ion concentration and an acidic pH. In a typical acid-stabilized calcium carbonate slurry of the invention, the acid-stabilizer is present in an amount sufficient to provide a calcium ion concentration of about 1 millimolar to about 5 molar, preferably from about 1 to about 120 millimolar. The invention also relates to a method of making the acid-stabilized calcium carbonate slurry of the invention, to a method of forming a filled paper, that includes the step of adding the acid-stabilized calcium carbonate slurry of the invention to a papermaking pulp in a process for making acid paper, and to a filled paper produced according to the method of the invention.

    摘要： Process for producing paper and paperboard, which comprises adding to a cellulose pulp stock a natural starch and an aluminum and/or iron salt. The so obtained cellulose pulp stock is then submitted to dewatering and subsequent calendering according to conventional techniques. In such a way, retention of the natural starch on the cellulose fibers is remarkably increased. To further increase retention it is particularly advantageous to pre-mix the natural starch with the aluminum and/or iron salt and then to add the resulting mixture to the cellulose pulp stock.
