titleOfInvention |
Negative thermal expansion material and composite material containing same |
abstract |
The invention provides a negative thermal expansion material having excellent dispersibility and filling characteristics with respect to a positive thermal expansion material. The method for solving the problem of the invention comprises the following steps: the negative thermal expansion material of the present invention has a BET specific surface area of 2m 2 Spherical zirconium phosphotungstate of less than/g. The sphericity is preferably 0.90 or more and 1 or less. It is also preferable that at least Mg and/or V is further contained as an element of the subcomponent. The content of the subcomponent element is preferably 0.1 to 3 mass%. The average particle diameter is preferably 1 μm or more and 50 μm or less. |
