<p>Disclosed is a sintered ceramic body with high strength, excellent fireproofness (heat-resistance) and machinability characterized by comprising a composition of CaO-SiO2-MgO as surrounded by the points 1, 2, 3, 4, 5, 6 and 7 in Fig. 1. There is also disclosed is a method of manufacturing a sintered ceramic body with excellent fireproofness (heat-resistance) and machinability characterized by preparing a raw material composition which consists of CaO, SiO2 and MgO as surrounded by the points 1, 2, 3, 4, 5, 6 and 7 in Fig. 1 and then firing the composition at a temperature higher than 1200 DEG C and up to 1350 DEG C.</p> |
