Sodium amalgams: phase diagram, structural chemistry and thermodynamic data, a summary of recent developments

Journal of Alloys and Compounds, 1997
Abstract A summary of recent results concerning the binary system NaHg is given. Characterized by six thermodynamically stable solids: NaHg4, NaHg2, NaHg (α,β,γ), Na3Hg2, Na8, Hg3 (α, β, γ) and Na3 Hg (α,β), their crysta, structures could be solved by single crystal X-ray studies, except those of NaHg4 and β-NaHg.

Structural chemistry and number theory amalgamized: crystal structure of Na₁₁Hg₅₂

Acta Crystallographica Section B Structural Science, Crystal Engineering and Materials, 2015
The recently elucidated crystal structure of the technologically important amalgam Na11Hg52is described by means of a method employing some fundamental concept of number theory, namely modular arithmetical (congruence) relations observed between a slightly idealized set of atomic coordinates.

Surface Chemistry of a High-copper Dental Amalgam

Journal of Dental Research, 1998
In amalgam, mercury is intended to take the form of stable intermetallic compounds. Any mercury leakage must therefore come from free mercury not involved in such compounds. Thus, a knowledge of the exact surface chemistry of dental amalgam is necessary if this phenomenon is to be understood. From XPS and EDS analyses, a model of the surface chemistry

A new approach to measurement of the donor strength and co-ordination chemistry of various solvents by oxidation of metal amalgam electrodes in dichloromethane

Journal of the Chemical Society, Dalton Transactions, 1988
Electrochemical oxidation of thallium, lead, and cadmium amalgam electrodes in dichloromethane containing 0.2 mol dm–3[NBu4][PF6] produces highly activated metal cations. The cations generated in this non-co-ordinating medium react rapidly with added donor solvents (solv) such as dimethyl sulphoxide, dimethylformamide, tetrahydrofuran, methanol ...

Changed Clinical Chemistry Pattern in Blood After Removal of Dental Amalgam and other Metal Alloys Supported by Antioxidant Therapy

Biological Trace Element Research, 2007
This study aimed to investigate a possible connection between removal of dental amalgam restorations supported by antioxidant therapy and indicative changes of clinical chemistry parameters. A group of 24 patients, referred for complaints related to amalgam restorations, underwent a removal of their amalgams. All patients were treated with antioxidants
