4. Electrolysis. In the electrolysis department, the zinc contained in the solution is deposited onto aluminum cathodes in a process called electrowinning. This happens by passing an electric current through cathodes and anodes. The cathodes are removed from the cells and the zinc sheets are stripped from the cathodes and sent to casting.

Abstract. The suitability of Glass Ionomer Cements (GICs) for use in orthopaedics is retarded by the presence in the glass phase of aluminium, a neurotoxin. Unfortunately, the aluminium ion plays an integral role in the setting process of a GIC and its absence is likely to hinder cement formation. However, zinc oxide, a bacteriocide, can act ...
zinc and lead, and the recovery of bismuth has not attracted sufficient attention [17, 18]. In view of this, a hydrometallurgical process for the recovery of zinc, bismuth, and lead from Zn-rich dust was proposed. Firstly, sulfuric acid was used as leaching agent and zinc was leached and recovered as zinc sulfate in the leachate. Then Bi

Abstract. Bismuth layer-structured ferroelectrics (BLSFs) are one of the candidates for lead-free piezoelectrics for high temperature and high frequency applications. BLSFs have a layer structure with a general formula (Bi 2 O 2 ) (A m−1 B m O 3m+1 ), where A denotes mono-, di-, or trivalent ions with a large ionic radius, and B denotes …
Ferroelectric materials have drawn widespread attention due to their switchable spontaneous polarization and anomalous photovoltaic effect.

The blast furnace produces an ordinary grade of zinc containing 1.2 percent lead. This can be used in general galvanizing, but an additional refluxing operation must be performed to produce high-grade zinc. The operation is performed in two fractionating columns, each consisting of a series of superposed rectangular trays made of bonded silicon ...

In the process, metal bismuth is combined with other impurity metals displaced by iron at the same time to produce crude bismuth. Precipitation smelting is applicable to process high-grade bismuth sulfide concentrate with less impurities such as lead, arsenic, and antimony. The grade of crude bismuth produced with the method is …

In the last decade, aqueous zinc-based batteries (AZBs) have attracted significant research attention owing to their intrinsic security, low cost, and eco-friendliness. Nevertheless, the development of AZBs has been hindered by the sluggish kinetics of cathode materials. Bismuth chalcogenides were recently employed as cathode …
