Abstract
A ceramic composition is provided with a glass based material including SiO2, Al2O3, B2O3, and at least one selected from a group of Cao and MgO, and particles dispersed in the glass based material. The particles includes CaSiO3 or MgSiO3 as a main component. A sintered state of the ceramic composition has an anti-bending strength of 1500 kg/cm2 or higher.
Claims6
A ceramic composition comprising:
- a glass based material including SiO2, Al2O3, B2O3, and at least one selected from the group consisting of CaO and MgO;
- and
- particles dispersed in the glass based material, the particles including CaSiO3 or MgSiO3 as a main component, wherein a sintered state of the ceramic composition has an anti-bending strength of 1500 kg/cm2 or higher and wherein said ceramic composition includes less than or equal to 70 weight % of the glass based material and more than or equal to 30 weight % of the particles, the glass based material including 25-60 weight % of SiO2, 5-25 weight % Al2O3, and 5-25 weight % B2O3, and 5-30 weight % of CaO and/or MgO.
A sintered ceramic material obtained by sintering a molded ceramic composition, wherein the ceramic composition comprising:
- a glass based material including SiO2, Al2O3, B2O3, and at least one selected from the group consisting of CaO and MgO;
- and
- particles dispersed in the glass based material, the particles including CaSiO3 or MgSiO3 as a main component, wherein a sintered state of the ceramic composition has an anti-bending strength of 1500 kg/cm2 or higher and wherein said ceramic composition includes less than or equal to 70 weight % of the glass based material and more than or equal to 30 weight % of the particles, the glass based material including 25-60 weight % of SiO2, 5-25 weight % Al2O3, and 5-25 weight % B2O3, and 5-30 weight % of CaO and/or MgO.
