PRODUCTION PROCESS OF SINTERING TEMPERATURE REDUCING ADDITIVE FOR CERAMIC BODIES, COMPOSITION AND RESULTING PRODUCT
The present invention relates to a process (10) for the production of additive (11) that reduces the sintering temperature of ceramic bodies and obtaining traditional ceramic floors and wall tiles, porcelain tiles, earthenware bodies, table porcelain, stoneware among others; said additive (11) production process provides for a dosage stage (T1) with potassium feldspar, ground to reach a granulometry of 100 to 200 mesh size and dosed together with an additional component, sodium tetraborate anhydrous, ground in a mill to reach a granulometry of 14 to 80 mesh size, and both sodium tetraborate anhydrous and potassium feldspar can be presented ground or in the form of larger granules; and the said process (10) provides for a cooling stage (T4) consisting of the application of the heated additive (11) body in a tank or adequate reservoir containing water, in order to cool the body and form glass granules; the said additive consists of potassium feldspar and sodium tetraborate anhydrous, presenting quantitative values in percentages, being 26. 0% of sodium tetraborate anhydrous and 74.0% of potassium feldspar, obtaining a product resulting in additive (11) that reduces the sintering temperature of ceramic bodies.
