that of the other static dissolution tests (pH 1.0, 1.5 and 1.8) probably due to fast formation and precipitation of ferric-hydroxide (pH>1.82 was recorded after 240 min of dissolution). It could...], according to which, high acidity levels prevent the hydrolysis/precipitation of Fe. Sulphur (S0) was also observed in the solid residues as the reaction product (Reaction (1)), as also reported......
batteries,#7 Circular economy三个聚类群. 对三大聚类研究群内重要高频关键词汇总整理,具体信息见下表9. 从表9中统计信息可见,对于金属湿法富集,提取工艺研究群而言,本研究群的高频关键词主要包括Cobalt(钴),Li(锂),Acid(酸),Extraction(萃取),Precipitation(沉淀)等.退役锂电池经预处理过程获得电极材料,电极材料的湿法处理过程是整个回收流......
by increasing sintering activity, which can be realized by using ultrafine and hypoxic powder especially for copper. Copper powder has been produced with various approaches such as chemical precipitation......
). As it was shown previously, the average non-equilibrium cooling rate during squeeze casting of the insert alloy was predicted to be about 14 °C/s [21]. According to CULLITON et al [42], precipitation... to have been available during solidification of the insert alloy. This has inhibited precipitation and growth of the coarse needle-like intermetallic phases in the microstructure of as squeeze cast insert......
method, solid state method, co-precipitation method, sol-gel method, hydrothermal method, reverse microemulsion method and template method. These preparation methods have both advantages... solid compounds can be all used to synthesize perovskite-type oxides, including thermal decomposition, co-precipitation, solid state, sol-gel, reverse microemulsion, hydrothermal and template method......
to the SAW also resulted in reduced distortion. 5.3 Hardness AAs are divided into two categories, i.e. heat- treatable (precipitation hardened) AAs and non heat- treatable (solid-solution hardened) AAs [104......
result is that the heat-treatable Al matrix still has a strong precipitation-hardening ability after the commercial T6 heat treatment, which suggests that the addition of TiB2 does not significantly affect......
