WebSmall symmetrical molecules (nonpolar molecules), such as H 2, N 2, O 2, and F 2, have weak attractive forces and form molecular solids with very low melting points (below −200 °C). Substances consisting of larger, nonpolar molecules have larger attractive forces and melt at higher temperatures. WebThe crystalline structure of moissanite tended to be destroyed at a relatively low temperature in the presence of iron, and moissanite was only detected after complete conversion of iron to ferrosilicon. To sum up, there are still many problems with the influence of residual carbon on the coal ash melting process.
