| 7. | ( 6 ) cryolite corrosion resistance of si3n4 / sic is very excellent in air atmosphere . the property of si3n4 / sic is the best among si3n4 / sic si2n2o / sic and o ' - sialon / sic 西北工业大学工学硕士论文( 6 )在970的空气介质中, si3n4 / sic具有优异的抗冰晶石侵蚀性能。 |
| 8. | The stage of alumina extraction is excluded in these technologies of aluminium production , and chloride method of electrolysis allows to decrease electric power costs by 30 - 35 % in comparision with electrolytic aluminium extraction from cryolite - alumina melts 从氧化铝中提取铝的方法已被排除在铝的生产技术之外,而且电解氯化物方法相对于电解冰晶石氧化铝融解物的方法,可以减少电力费用30 - 35 % 。 |
| 9. | The results show that the main matter for the electroosmosis is sodium - fluorine compound ; the depth and matter for the electroosimosis increase with increase of alumina concentration and magnesium fluoride content , and the electroosmosis deepens sharply when the cryolite mole ratio reaches 2 . 0 结果表明:电渗的主要物质是钠氟化合物,随着氧化铝浓度及氟化镁含量的增加,电渗的深度及电渗的物质量增加;当冰晶石分子比达到2 . 0时,电渗的深度急剧增加。 |
