| titleOfInvention | Method for synthesizing spherical siderite single crystal by using precursor at high temperature and high pressure |
| abstract | The invention discloses a method for synthesizing a spherical siderite single crystal by using a precursor at high temperature and high pressure, which comprises the steps of firstly, grinding and uniformly mixing analytically pure barium carbonate and synthesized ferrous carbonate in a molar ratio of 1:1 as starting raw materials, and reacting at high temperature and high pressure to obtain a barium carbonate iron powder crystal precursor; and then grinding and mixing the barium carbonate iron powder crystal precursor and anhydrous oxalic acid according to the molar ratio of 1:1 to prepare a sample, assembling the sample in a high-pressure synthesis assembly block, placing the assembly block in a cubic apparatus large press to perform high-temperature high-pressure reaction to prepare a golden spherical siderite single crystal sample, and solving the problem that the existing spherical siderite seed crystal cannot be artificially synthesized. |
