Abstract
The present invention provides a ceramic powder, in which β-eucryptite or a β-quartz solid solution is precipitated as a main crystal phase, and which includes TiO2 and/or ZrO2.
Claims12
A ceramic powder, in which β-eucryptite or a β-quartz solid solution is precipitated as a main crystal phase, in which TiO2 and/or ZrO2 is solid solved, and which has an average particle diameter D50 of 7 μm or less,
- wherein the ceramic powder is substantially free of a glass phase.
A method of producing a ceramic powder, comprising the steps of:
- firing a raw material batch to obtain, through a solid phase reaction, a sintered body in which β-eucryptite or a β-quartz solid solution is precipitated as a main crystal phase, and which comprises TiO2 and/or ZrO2, and
- pulverizing the sintered body to obtain a ceramic powder,
- wherein the ceramic powder has an average particle diameter D50 of 7 μm or less;
- and
- wherein the ceramic powder is substantially free of a glass phase.
