thermal diffusivity iron chromite

  • Application of transient thermal analysis for the assessment ...

    In this study, FEM based transient thermal analysis yielded the comparative performance four types of sands: Cerabead, Zircon, Chromite and Silica with respect to sand fusion. This was achieved by studying the effect of heat diffusivity of these sand types on temperature distribution in the mould during casting solidification.

  • Physical properties of magmas - UW Courses Web Server

    Thermal conductivity (K) is a measure of the rate at which heat is conducted through rocks and magmas. [Units: J cm-1 s-1 deg-1]. Typical values for rock range from 10-2 to 2.5 x 10-2 J cm-1 s-1 deg-1. In cooling rate calculations we use the thermal diffusivity (k): k = K / ρC (C is the specific heat). [Units of k: cm2 s-1].
