A cordierite sintered body and a member for semiconductor manufacturing apparatus are disclosed. The cordierite sintered body includes a crystal phase and an amorphous phase. The crystal phase includes a main crystal phase that essentially consists of cordierite crystal grains; and a sub crystal phase that includes sub crystal grains containing alumina, mullite or sapphirine. The amorphous phase contains calcium and is located at grain boundaries of the cordierite crystal grains and the sub crystal grains. A crystal phase proportion of the main crystal phase to the crystal phase (or total of the main crystal phase and the sub crystal phase) is 95% to 97.5% by mass or less. A crystal phase proportion of the sub crystal phase to the crystal phase is 2.5% to 5% by mass or less. The sintered body contains calcium by 0.4% to 0.6% by mass or less in terms of CaO.

An alumina sintered article comprising 99.3 mass % or more Al in terms of AlO, strontium and silicon is disclosed. The alumina sintered article also comprises alumina crystal grains and an oxide crystal comprising aluminum, silicon, strontium located at a triple pocket surrounded by three or more alumina crystal grains. The alumina sintered article improves dielectric loss in the megahertz to gigahertz bands while maintaining corrosion resistance, mechanical properties of alumina.

Alumina sintered article

Alumina/zirconia ceramics containing AlOin an amount of not less than 65 mass % and ZrOin an amount of 4 to 34 mass %, and further containing TiO, MgO and SiO. The ceramics effectively suppresses the growth of shape isotropic particles of alumina, suppresses the growth of zirconia particles, and has a high strength and a high hardness. Besides, the ceramics containing SrO features a high fracture toughness.
