Refractory Elements

Using research by Wood (2019), any of the elements with a relatively high condensation temperature of 1291 K < TC,50 < 1806 K in the solar nebula1. They are the first elements to condense out of a cooling gas. Refractory elements are the main building blocks of rocky planets, dwarf planets and moons, inner belt asteroids and a portion of other icy moons, outer-belt asteroids, gaseous planets and trans-neptunian objects2.
