Chapter 18, Problem 18.38P

Interpretation Introduction

Interpretation:

Pilling Bed worth ratio is to be identified and the behavior of the given oxides is to be explained.

Concept introduction:

The Pilling-Bedworth relation is:

  $\text{P}\text{.W=}\frac{{\text{MW}}_{\text{oxide}}{\text{×ρ}}_{\text{metal}}}{{\text{n×MW}}_{\text{metal}}{\text{×ρ}}_{\text{oxide}}}$ - (1)

Where M.W is atomic or molecular mass, $\text{ρ}$ is density, and n is number of atoms per molecule of the oxide.
