Wszystkie te niedogodnosci usuwa sposób wedlug wynalazku polegajacy na zmieszaniu kaolinu z sola lub solami amonu, a nastepnie ogrzanie tej mieszaniny w temperaturze do 1200°C, Kaolin miesza sie z sola lub solami amonu w ilosciach od 1-20% w stosunku wagowym.Przyklad: Kaolin surowy zmieszano z 20% wagowymi NH4CI i ogrzano w temperaturze 950° C w czasie 1 godziny. Po tym zabiegu bialosc kaolinu wynosila 91%. Natomiast kaolin bez tego dodatku — ogrzany w tych samych warunkach posiadal bialosc 78%. PL PLAll these disadvantages are eliminated by the method according to the invention, which consists in mixing kaolin with ammonium salt or salts, and then heating this mixture at a temperature of up to 1200 ° C, Kaolin is mixed with salt or ammonium salts in amounts ranging from 1-20% by weight. Crude kaolin was mixed with 20 wt% NH4Cl and heated at 950 ° C for 1 hour. After this treatment, the whiteness of kaolin was 91%. On the other hand, kaolin without this additive - heated under the same conditions, had a whiteness of 78%. PL PL
