Question

How will the melting point of a beryllium-gold alloy compare to that of pure gold?

Answer 1

The melting point of a pure substance is always higher and has a smaller variation range of the melting point of an impure substance . The more impure it is , the lower the melting point and the wider the range of variation. Eventually, a melting point minimum is reached. The mix ratio which results in the lowest possible point of melting is known as the eutectic point , belonging to each atom temperature of the substance to which it is subjected to fusion .

There are certain specific concentrations of each alloy for which the melting temperature is unified . This concentration and the obtained alloy are called eutectic , and has a melting point lower than the melting points of the components
