| titleOfInvention | Synthesis of Low-Thermal-Expansion (ZrO)2P2O7 powders |
| abstract | In the present invention, ZrO (NO 3 ) 2 .xH 2 O and P 2 O 5 as starting materials are prepared in a molar ratio of 2: 1, the starting material is dissolved in distilled water, and the PVA solution is mixed to prepare a precursor mixture (ZrO) 2 P 2 O 7 powder, comprising the steps of: preparing a precursor of a precursor in a gel state, and drying the precursor in a gel state, followed by heat treatment of the dried precursor. The low thermal expansion ceramics of the present invention can synthesize a stable α phase (ZrO 2 P 2 O 7 powder) at a PVA content of 12: 1 and a heat treatment at 1200 ° C. for 4 hours, and a negative tone of -2.5 × 10 -6 / It has thermal expansion coefficient and can be used as a low thermal expansion filler. |
