| 单词 | aluminium oxide |
| 例句 | After 3 hours, the aluminium had reacted with the cathode material and produced a mixture of insoluble aluminium oxides, as well as metallic cobalt and water-soluble lithium oxides. Could Grinding Up Lithium Batteries Help Recycle Them? 2023-03-30T04:00:00Z The electrolysis process, is energy intensive - electricity is used in the extraction of aluminium from aluminium oxide, which itself comes from the aluminium ore, or bauxite, mined out of the ground. Why the 'shocking' price of aluminium matters 2022-05-12T04:00:00Z The key advance is the hemispherical retina: a dense array of light-sensitive nanowires held in the pores of an aluminium oxide membrane. Artificial eye boosted by hemispherical retina 2020-05-19T04:00:00Z Conventionally, it was difficult to produce anything more than 50% using FT synthesis, in a process usually based on iron or cobalt catalysts supported on silica or aluminium oxide. Clever chemistry offers new source of jet fuel 2018-09-17T04:00:00Z It’s a two-step process: refine aluminium oxide powder from bauxite ore and then convert it to aluminium in smelters. Aluminium producers promise a cleaner smelting pot 2018-05-14T04:00:00Z This prevented the formation of insoluble lithium aluminium oxides, which lock up the lithium. Could Grinding Up Lithium Batteries Help Recycle Them? 2023-03-30T04:00:00Z So engineers decided to coat the tubes with aluminium oxide to reflect sunlight and keep them beneath that 60 °C threshold. The $2.4-billion plan to steal a rock from Mars 2017-01-17T05:00:00Z Their calculations show that adding layers of aluminium oxide to the mix and increasing the number of layers to 300 should increase that efficiency to 40%, far better than even the most efficient fluorescent lights. Light-bulb moment 2016-01-14T05:00:00Z This replaces the aluminium oxide with titanium oxide, which is more conductive. Tiny balls of fire 2015-08-13T04:00:00Z But even if Elysis does succeed, aluminium production will still yield emissions from mining, aluminium oxide processing and transport. Aluminium producers promise a cleaner smelting pot 2018-05-14T04:00:00Z Studart, similarly, gets his wide range of elasticity by reinforcing polyurethane with differently sized particles of tougher aluminium oxide or a synthetic clay. Structure: Artificial armour : Nature : Nature Publishing Group 2015-03-24T04:00:00Z Their raw material is aluminium oxide, which is stronger than steel - but like most ceramics, it is usually terribly brittle. Magic 'metamaterials' storm physics 2015-03-04T05:00:00Z Note: Sapphires can also be yellow, purple, orange or green – different compositionally from emeralds – while red aluminium oxide is a ruby. iPhone 6 Sapphire Display: Everything You Need To Know 2014-07-25T04:00:00Z It functions chiefly as an acidic oxide, being less basic than aluminium oxide, and forming no stable oxy-salts. Encyclopaedia Britannica, 11th Edition, Volume 12, Slice 2 "Gloss" to "Gordon, Charles George" 2011-10-31T02:00:28.703Z It is a bright green powder, and when ignited strongly becomes almost insoluble in acids, as is also the case with aluminium oxide. An Elementary Study of Chemistry In what respects does aluminium oxide differ from calcium oxide in properties? An Elementary Study of Chemistry |
