<P>PROBLEM TO BE SOLVED: To provide a pottery for microwave heating and a method for manufacturing the same since a usual pottery has a low heating effect in a microwave oven, therefore, it is unsuitable to cooking which roasts fish and meat, however, when a cooking utensil itself is heated strongly, cooking which roasts fish and meat by gas fire or charcoal fire can be performed, moreover, boiled rice can be attached with scorch, or is inserted into two flat plates and can be burned to be a rice cracker. <P>SOLUTION: Thermal shock resistance of a green body must be high in order to highly efficiently heat a pottery vessel for food cooking by a microwave oven. Therefore, a green body composition is made such that a cordierite quality and β spodumene of a low thermal expansion property deposit in a raw material blending. For a material for raising heating efficiency, the calcination synthesis of stannic acid antimony (Sb<SB POS="POST">2</SB>O<SB POS="POST">5</SB>-SnO<SB POS="POST">2</SB>) and transition element compound oxides, such as Fe<SB POS="POST">2</SB>O<SB POS="POST">3</SB>, and Cr<SB POS="POST">2</SB>O<SB POS="POST">3</SB>, MnO<SB POS="POST">2</SB>, CoO, and CuO is carried out, and synthesized products are added to a green body and a glaze, thereby the pottery vessel which efficiently heats is manufactured. <P>COPYRIGHT: (C)2012,JPO&INPIT |
