COMPOSITION INCLUDING FIBER FOR MANUFACTURING HIGH STRENGTH LIGHTWEIGHT CERAMIC WARE, METHOD FOR MANUFACTURING HIGH STRENGTH LIGHTWEIGHT CERAMIC WARE USING COMPOSITION, AND HIGH STRENGTH LIGHTWEIGHT CERAMIC WARE MANUFACTURED BY MANUFACTURING METHOD

摘要

Disclosed in the present invention is a composition for manufacturing high strength lightweight ceramic ware including i) 100 parts by weight of solid containing 40-75 wt% of SiO2, 10-35 wt% of Al2O3, 1-15 wt% of K2O, 1-15 wt% of Na2O, 0.1-15 wt% of CaO, and 0.1-15 wt% of MgO; ii) 40-60 parts by weight of moisture; iii) 0.1-10 parts by weight of a pore former; and iv) 0.5-10 parts by weight of fiber, a method for manufacturing high strength lightweight ceramic ware using the composition, and high strength lightweight ceramic ware manufactured by the manufacturing method. If ceramic ware is manufactured by using the composition for manufacturing high strength lightweight ceramic ware including fiber according to the present invention, the lightweight ceramic ware has significantly improved strength and fracture toughness through a fiber reinforcement effect in the ceramic ware of the fiber uniformly dispersed in the ceramic ware to perfectly solve problems of reduction of strength and fracture toughness caused by pores formed inside the ceramic ware by the pore former added for light weight, in order to be used in manufacturing of such as hygienic ceramic ware, tableware, or tile with high strength and light weight.;COPYRIGHT KIPO 2015
