| abstract |
The present invention provides a new method capable of producing an aluminum titanate-based ceramic with a small volume change due to heat. An aluminum titanate system comprising a step of firing a raw material mixture including a titanium source powder, an aluminum source powder, and a precursor mixture that is led to a negative thermal expansion material by firing and / or a negative thermal expansion material. A method for producing a ceramic, and an aluminum titanate-based ceramic obtained by the production method. A suitable example of the negative thermal expansion material is zirconium tungstate.
