摘要： The invention relates to a method of making paper or paperboard comprising the steps of; a. providing a stock suspension; b. adding a mixture of alkali-metal silicate and precipitated calcium carbonate to said stock suspension; c. adding an acidic media to said stock suspension substantially directly before and/or after step (b) d. forming a web of the stock suspension obtained in step (d) e. drying said web. The addition of a mixture of alkali-metal silicate and PCC and of an acidic media to the stock suspension in accordance with the invention improves the bonding between the fibers and the filler (PCC), whereby problems related to dusting is decreased. Moreover, the method enables the addition of a higher amount of fillers to the paper without substantially affecting the strength.
