▎ 摘  要

NOVELTY - Ceramic sheet comprises 20-30 pts. wt. cordierite, 15-25 pts. wt. fluorite, 5-10 pts. wt. potassium feldspar, 3-6 pts. wt. self-cleaning additives, 1-2 pts. wt. barium titanate sintering aid, 0.2-0.6 pts. wt. talc, and 0.1-0.3 pts. wt. modified nano-silica. USE - The ceramic sheet is useful in high-level curtain wall, and high-end furniture. ADVANTAGE - The sheet has enhanced easy-cleaning effect, and increased activity. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for preparing ceramic sheet, comprising (i) adding cordierite, fluorite, potassium feldspar, self-cleaning additives, barium titanate sintering aids, talc, and modified nano-silicon dioxide into mixer, completely mixing and stirring, conveying into ball mill for ball milling, passing 200 mesh, and pre-pressing with pressing pressure of 4000-5000 tons/m, and pressing thickness of 3-6 mm, (ii) calcining and sintering at 1360-1370℃ for 2-3 hours, completing sintering, and cooling temperature to room temperature, and (iii) spraying surface of sintered material with an easy-to-clean material with thickness of 1-3 mm, drying at 110-120℃ for 20-30 minutes, and drying to obtain ceramic sheet.
