Definitions

  • the present invention (1) is made of zirconium phosphate tungstate containing an Al atom and has a thermal expansion coefficient of ⁇ 2.0 ⁇ 10 ⁇ 6 to ⁇ 3.3 ⁇ 10 ⁇ 6 / K. And a negative thermal expansion material.
  • the negative thermal expansion material of the present invention is suitably produced by the method for producing zirconium tungstate phosphate of the present invention described below.
  • the method for producing zirconium tungstate phosphate of the present invention comprises mixing a W source, a Zr source, a P source, and an Al source to form a W source, a Zr source, a P source, and an Al source.
  • the method for producing a negative thermal expansion material having the following, in the first step, the content of Al atoms is 100 to 6000 mass ppm with respect to the Al-containing zirconium phosphate tungstate obtained by performing the third step.
  • the method for producing a negative thermal expansion material comprises mixing an Al source with the slurry.
  • the Al source according to the first step is a compound having an Al atom.
  • the Al source include aluminum nitrate, aluminum sulfate, aluminum biphosphate, and aluminum lactate. Of these, aluminum nitrate is inexpensive, easily available industrially, and has good negative thermal expansion. This is preferable because a negative thermal expansion material having characteristics can be easily obtained.
  • the method of preparing the slurry in the first step is not particularly limited as long as a slurry in which each raw material is uniformly dispersed is obtained.
  • an aqueous slurry in which the W source is uniformly dispersed is prepared, and the P source and Zr are added thereto. It is preferable to mix the source and then the Al source, since it is easy to prepare an aqueous slurry in which each raw material is uniformly dispersed.
  • the slurry can be subjected to a wet pulverization treatment with a media mill if necessary.
  • the negative thermal expansion material obtained by performing the method for producing the negative thermal expansion material of the present invention is a single-phase Al-containing zirconium tungstate phosphate which is X-ray diffraction.
  • the negative thermal expansion material obtained by performing the method for producing a negative thermal expansion material of the present invention is zirconium phosphate tungstate containing an Al atom when a compound having a subcomponent element is not used. When a compound having an element is used, zirconium tungstate phosphate containing an Al atom and an accessory component element is used.
  • the composite material of the present invention is a composite material comprising the negative thermal expansion material and the positive thermal expansion material of the present invention.
