Abstract
A tile comprises a fire resistant ceramic, which is obtained by mixing and kneading defatted bran obtained from rice bran and a thermosetting resin, primarily baking the resulting mixture in an inert gas at 700° C. to 1000° C., crushing the resulting product into carbonized powder, mixing and kneading the carbonized powder with a ceramic powder, a solvent and, optionally, a binder to provide a plasticized mixture (ceramic-solvent mixture), pressure forming the mixture at a compression pressure of 10 MPa to 100 MPa, and heat treating the resulting compact again in an atmosphere of an inert gas at 500 to 1400° C.
