That is not always the case. If you take a substance with a melting point of 500 degrees and add a substance with a melting point of 400 degrees than the melting point of the compound is going to lie between 400 and 500 degrees. If you take a substance with a melting point of 500 degrees and add a substance with a melting point of 600 degrees then the melting point is going to lie between 500 and 600 degrees. “Impurities” are simply unwanted substances with low melting points.
