Silfur

Silfur is the Icelandic name for the chemical element silver, known in the periodic table by the symbol Ag and atomic number 47. Silver is a soft, white lustrous metal valued for its high electrical and thermal conductivity, as well as its high reflectivity.

In terms of properties, silver is highly malleable and ductile, with a melting point of 961.8 degrees Celsius and a boiling point of 2162 degrees Celsius. It is relatively resistant to corrosion in plain air but tarnishes when exposed to sulfur compounds, forming silver sulfide on the surface.

Occurrence and production: Silver occurs in native form and in minerals such as argentite (silver sulfide, Ag2S) and chlorargyrite (silver chloride, AgCl). Most silver is obtained as a byproduct of mining other metals, including copper, lead, and gold; a substantial portion is also recovered from recycled scrap material.

Uses: Silver has longtime value in coins, jewelry, and decorative items. It is widely used in electronics and electrical contacts due to its superb conductivity, in solar panels, certain catalysts, and specialized coatings and mirrors. Historically, silver halides were central to traditional photography.

Context and trade: As a precious metal, silfur is traded internationally and tracked as a commodity. Its price fluctuates with market demand across industries such as technology, jewelry, and mineral extraction. The term silfur also appears in Icelandic language and culture to denote silver in general use, reflecting its historical importance in Icelandic trade and craftsmanship.
