PROPERTIES OF SOLDERS - Farnell element14

application of a high melting point alloy is the soldering of joints close to each other in such a way that the first joint is not re-melted while the later joint, or joints, are being made. The first joint is made with HMP alloy (296-301°C) and the further joints are made with successively lower melting point alloys, for example - 60/40 tin/lead

Predicting ionic liquid melting points using machine ...

 · The melting point (T m) of an ionic liquid (IL) is of crucial importance in many applications.The T m can vary considerably depending on the choice of the anion and cation. This study explores the use of various machine learning (ML) methods to predict the melting points (− 96 °C–359 °C range) of structurally diverse 2212 ILs based on a combination of 1369 cations and 141 anions.
