Chapter 15, Problem 15.17P

Interpretation Introduction

Interpretation:

Silicon carbide with a density of 3.1 g/ ${\text{cm}}^{\text{3}}$ and SiC part is obtained by occupying a volume of 500 ${\text{cm}}^{\text{3}}$ and weighing 1200g. The bulk density, true porosity and volume fraction of total porosity that includes closed pores needs to be determined.

Concept Introduction:

Silicon carbide also known by the name carborundum acts as semiconductor containing silicon and carbon. Grains of silicon carbide can be bonded together by sintering process to form hard ceramics.

Properties of silicon carbide:

• Its density is 3.1g/ $c{m}^3$ .
• It is insoluble in water.
• Its chemical formula is Csi.
• It appears yellow to green to bluish black, iridescent crystals.
