<P>PROBLEM TO BE SOLVED: To provide a ceramic formed by using a waste as a main material which has no abnormal expansion and a small thermal expansion coefficient, stable in firing, can be formed as a large product, and can be fired rapidly and at a low temperature, can effectively utilize the waste to be utilized for various applications, and its manufacturing method. <P>SOLUTION: This ceramic formed by using a waste as a main material is formed by firing a coal ash, or the coal ash and at least one of a lime-based waste and a glass-based waste. Also, this manufacturing method of the ceramic by using a waste as a main material includes a process for producing a ceramic raw material by using the coal ash and at least one of the lime-based waste and the glass-based waste as a main material, a compacting process for compacting the ceramic raw material, a process for drying the compact and a firing process for baking the dried compact. <P>COPYRIGHT: (C)2008,JPO&INPIT |
