| titleOfInvention | High-temperature high-pressure synthesis of one-dimensional thermal expansion material calcium carbonate manganese crystal |
| abstract | The invention discloses a method for synthesizing one-dimensional thermal expansion material calcium carbonate manganese crystal at high temperature and high pressure, which uses analytically pure calcium carbonate CaCO 3 Analytically pure manganese carbonate MnCO 3 And analytically pure anhydrous oxalic acid H 2 C 2 O 4 Uniformly mixing and grinding the raw materials with a molar ratio (1-x) x:1 as an initial raw material, wherein x is more than or equal to 0.70 and less than or equal to 0.75, and reacting at high temperature and high pressure to obtain calcium carbonate, manganese carbonate and Ca 1‑x Mn x CO 3 (x is more than or equal to 0.70 and less than or equal to 0.75) crystal. The obtained synthetic product is a one-dimensional thermal expansion material, and the thermal expansion coefficients of the a axis and the b axis of the material are-5 multiplied by 10 ‑8 <α a ＝α b <5×10 ‑8 . Within the accuracy of the high temperature X-ray diffraction measurements, the thermal effects in the ab-plane were considered negligible. The invention aims to find the calcite type materialThe one-dimensional thermal expansion anomalous thermal effect material provides basis, and provides experimental basis for further development and application of the performance of the functional material. |
