Arsenical bronze - Wikipedia
网页Arsenical bronze is an alloy in which arsenic, as opposed to or in addition to tin or other constituent metals, is combined with copper to make bronze. The use of arsenic with copper, either as the secondary constituent or with another component such as tin, results in a stronger final product and better casting behavior.
Arsenical Bronze: Deadly Metal of the Bronze Age
网页2021年11月15日 — The ancients must have known the dangers of arsenic bronze, and the deadly trade-off it represented. It produced a hard, durable material that could be used to create tools, weapons, and decorative pieces. But it was killing the men who worked it.
网页bronze was predominantly a south-central Andean alloy, made by peoples inhabiting the cassiterite-rich zone of the southern Peruvian altiplano, Bolivia, and Yw Argentina (Ponce 1994; Mayer 1986; Gonzlez 1979). The southern zone also produced arsenic bronze in areas, such as the Atacama region in Chile, where substantial deposits of
Arsenic Bronze Dirty Copper or Chosen Alloy - Academia.edu
网页There, arsenic bronze was always predominantly a central and north-central Andean alloy, developed and used in large quantity in Ecuador and north and central Peru-precisely in the regions that are geologically rich in arsenic-bearing copper ores (Lechtman 1981, 1991; Hosler 1994; Shimada 1985).
Arsenical copper and bronze metallurgy during Late Bronze
网页2020年9月4日 — The copper-base metallurgy of the Iranian Plateau Bronze Age shows interesting aspects of transition from a long-time accidentally/intentionally copper-arsenic metallurgy to an innovative event giving rise to emergence …

网页2018年7月10日 — In order to understand solidification in the As-Cu binary system, providing useful information for the interpretation of ancient arsenical bronzes, we have measured phase formations in the regions of 1 to 15 wt pct arsenic at cooling rates from 2 K/min to 20 K/min, and compared them to two reference equilibrium phase diagrams. [ 2, 3] For most c...

网页2013年7月18日 — This article is dedicated to Ronald F. Tylecote. Archaeologists and historians of metallurgy have attempted to explain the gradual abandonment of arsenic bronze in favor of tin bronze in the ancient Old world by making comparisons between the mechanical properties of the two bronzes.
Arsenic loss during metallurgical processing of arsenical bronze
网页2017年8月19日 — Adding pure arsenic to molten copper results in about 10% loss of arsenic in the alloy. Thermodynamic calculations of (Mödlinger and Sabatini 2016) suggest that arsenic evaporation from a Cu-As melt is low mainly because of the good bonding of arsenic to copper. Our results confirm this hypothesis under argon atmosphere, since no …
