Abstract
A cordierite-based sintered body comprises cordierite as a primary crystal phase and LaMgAlOas a secondary crystal phase, wherein a ratio I(114)/I(004) is in the range of 0.01 to 0.8, where the I(114) denotes a peak intensity of a (114) plane of LaMgAlOas measured by powder X-ray diffractometry, and the I(004) denotes a peak intensity of a (004) plane of cordierite as measured by powder X-ray diffractometry. The disclosure is intended to enhance mechanical property and improve complex and fine processability for a cordierite-based sintered body without compromising low thermal expansibility, high dimensional long-term stability, high stiffness (high elastic modulus) and precision polishing characteristic.
