METHOD FOR MANUFACTURING ZIRCON-CAST PRODUCT AND ZIRCON-CAST PRODUCT
To provide: a method for manufacturing a zircon-cast product, capable of molding without separating the structure of the zircon-cast product, and capable of effectively inhibiting cracking that occurs during drying; and the zircon-cast product in which the separation of the structure and the occurrence of cracking are inhibited.SOLUTION: A method for manufacturing a zircon-cast product includes a casting step of casting a zircon-cast material, which is mainly composed of zircon, to obtain the zircon-cast product. The zircon-cast material contains: 20 to 40 mass% of zircon particles having a particle diameter of 1 to 5 mm; 25 to 45 mass% of zircon particles having a particle diameter of 0.1 to 1 mm; and 25 to 40 mass% of zircon particles having a particle diameter of 0.1 mm or less. A content of zircon particles having a particle diameter of 10 μm or less is 5 to 10 mass%.SELECTED DRAWING: None
