| titleOfInvention | Preparation method of crystalline zirconium tungstate having negative thermal expansion |
| abstract | The present invention relates to a negative coefficient of thermal expansion (negative thermal expansion) for having the crystalline zirconium tungstate (ZrW 2 O 8) production process and its crystal having a negative coefficient of thermal expansion which is produced by St. zirconium tungstate (ZrW 2 O 8) of the will be. More particularly, the present invention relates to a process for the preparation of an isotropic negative thermal expansion at a wide temperature range of 273 to 777 占 폚 through a low temperature heat treatment without using a conventional hydrothermal synthesis through a low temperature synthesis process by further adding a specific aprotic polar solvent or a proton- (ZrW 2 O 8 ), which exhibits a negative thermal expansion characteristic and exhibits excellent utilization properties, under atmospheric pressure so as to be mass-produced. |
