Disclosed is a manufacturing method of ceramic containing oyster shell powder. The manufacturing method of ceramic containing oyster shell powder comprises the steps of: a) obtaining oyster shell powder by washing oyster shells to eliminate impurities and salt, heating the washed oyster shells at 1150-1250°C to form pores at the spots where the impurities are removed, and crushing the shells into particles of 300 mesh; b) mixing 10-30 wt% of the oyster shell powder obtained from the step a) with 30-40 wt% of clay, pottery stone, and red clay powder as molding ingredients and 40-50 wt% of elvan stone, quartz, and feldspar powder as ceramic ingredients while keeping 5-15% of moisture content; c) molding the mixture produced the the step b) into a predetermined shape; and d) obtaining porous ceramic by firing the molded product from the step c) at 950-1100°C. According to the present invention, reusing oyster shells, which are marine waste, as ceramic, which is a building material, reduces the cost of disposal of oyster shells and prevents marine pollution. Manufacturing building materials with ceramic containing oyster shells improves deodorizing and absorption functions and removes volatile organic compounds. |
