Amalgam (chemistry) amalgams are known that are of interest mainly in the research context. Dentistry has used alloys of mercury with metals such as silver, copper, indium, tin and zinc. Amalgam is an "excellent and versatile restorative material" and is used in dentistry for a number of reasons. It is inexpensive and relatively easy to use and manipulate during placement; it remains soft for a short time so it can be packed to fill any irregular volume, and then forms a hard compound. Amalgam possesses greater longevity when compared to other direct restorative materials, such as composite. However, this difference has decreased
UCPH Department of Chemistry moved several times, usually to better surroundings. In 1962, Universitetets Kemiske Laboratorium moved to its present location in the H.C. Ørsted Institute (HCØ), named after Hans Christian Ørsted who discovered electromagnetism in 1820. It is less well known that H.C. Ørsted was also an able chemist, and that he was in fact the first person to isolate the element aluminium. UCPH Department of Chemistry The Department of Chemistry () is a department under the Faculty of Science, University of Copenhagen. It is the largest basic research institute in chemistry in Denmark, and is responsible for the teaching of chemistry at
