Sintered ceramic body, manufacturing method thereof, and ceramic structure
A manufacturing method of a sintered ceramic body according to the present invention mixes barium silicate with aluminum oxide, a predetermined glass material, and a predetermined additive oxide under adoption of preset conditions to prepare a material mixture. The manufacturing method then molds the material mixture to a molded object and fires the molded object at a temperature in a range of not lower than 850°C and not higher than 1000°C. One of the preset conditions is that the barium silicate is monoclinic and has an average particle diameter in a range of not less than 0.3 µm and less than 1 µm and a specific surface area in a range of not less than 5 m 2 /g and not greater than 20 m 2 /g. Another of.the preset conditions is that the aluminum oxide has an average particle diameter in a range of not less than 0.4 µm and not greater than 10 µm, a specific surface area in a range of not less than 0.8 m 2 /g and not greater than 8 m 2 /g, and a volume ratio of the aluminum oxide to the barium silicate in a range of not less than 10% by volume and not greater than 25% by volume. The sintered ceramic body thus obtained includes a glass component, an additive oxide component, and aluminum oxide particles added to and mixed with barium silicate and has a structure with hexagonal celsian located around outer circumferences of the aluminum oxide particles.
