Cordierite sintered body and method for producing same
The present invention relates to a cordierite sintered body containing all elements belonging to an element group M1 comprising calcium, magnesium, aluminum, and silicon, the content of the calcium being 0.06-3.40 mass% in terms of oxide, the content of the magnesium being 12.9 mass% or more, the content of element M2, which is a metal element other than the elements belonging to the element group M1, being 1.5 mass% or less, and the content of the element M2 being less than or equal to 0.5 mass% in terms of oxide. The cordierite sintered body has a porosity of 3.0 vol% or less, a four-point bending strength of 170 MPa or more, and a Weibull coefficient of 9.5 or more.
本发明涉及一种堇青石质烧结体，含有属于由钙、镁、铝和硅构成的元素组M1的全部元素，以氧化物换算计，上述钙的含量为0.06质量％～3.40质量％，上述镁的含量为12.9质量％以上，除属于上述元素组M1的元素以外的金属元、即元素M2的含量为1.5质量％以下，所述堇青石质烧结体的气孔率为3.0体积％以下，四点弯曲强度为170MPa以上，威布尔系数为9.5以上。
