| titleOfInvention | X-ray fluorescence spectra analyzes the MTG YBCO bulk method of ferrosilicon, Si-Ca-Ba, silicomanganese, ferro-aluminum or ferro-titanium sample |
| abstract | The invention discloses a kind of fast easy and avoid more reliably corrode platinum yellow gold crucible MTG YBCO bulk method.The method comprises the steps: a, take appropriate lithium tetraborate, lithium carbonate, oxygenant and test portion mixes, and is rolled into spherical; B, step a is wrapped up glomerate material put into the rebasing crucible of dag, be then placed in high temperature furnace and carry out molten prepolymer oxidation; Take out crucible, cooling, obtain the molten ball after pre-oxidation; C, take a certain amount of flux in platinum yellow crucible, add release agent and molten ball; Then be placed in the temperature environment melting 12 ~ 20min of 1100 ~ 1200 DEG C, take out, shake up, catch up with pure qi (oxygen) to steep; And then melting, take out, shake up, leave standstill cooling, obtain fuse piece.The present invention does not need to carry out the process of platinum yellow crucible wall built-up, easy operation, and the risk that when fundamentally avoiding pre-oxidation, platinum yellow crucible is etched, the even zero defect of fuse piece of preparation, meets X-ray fluorescence spectra and analyze requirement. |
