Non-radiation ceramic tile with high whiteness and manufacturing technique thereof

The invention discloses a ceramic tile with a high whiteness and no radiation as well as the manufacturing method thereof. The weight percents of the main raw materials of the ceramic tile is: 15-60 wt.% of burning talcum, 15-30 wt.% of feldspar, 5-30 wt.% of porcelain sand, 20-28 wt.% of black mud. The steps of manufacturing method is as follows: (1) calcining the talcum; (2) the manufacturing process is: raw materialsbatchingball millingremoving zirconiumspraying and millingmouldingdryingpenetratingburningpolishing; (3) doing a strict anti-pollution treatment after polishing. The calcining temperature of the talcum is: 1200 DEG C; the calcining temperature of the ceramic tile is 1210-1230 DEG C; burning period is: 60-80 minutes; whiteness is: about 80 DEG. The invention firstly does a pre-burning treatment to the talcum material in 1200 DEG C, thus it manages its sheet structure and removes volatile with a high temperature. The disposed material is without greasy texture and the dosage will not influence the products molding.
