Chapter 12, Problem 12.131SP

Interpretation Introduction

Interpretation:

The balanced equation for deposition of boron on a tungsten wire when boron trichloride vapor and gaseous hydrogen reacted should be determined.

Concept introduction:

The process that results in a final product of ceramic material from raw material is known as ceramic processing. The ceramic processing starts with a fine powder of raw material combined by an organic binder. Then it is shaped, compacted and at last sintered at a temperature of $1300-2000°\text{C}$ to decrease the voids between atoms and increase the density.

In order to increase the strength and fracture toughness of ceramics, the fine grains of ${\text{Al}}_{\text{2}}{\text{O}}_{\text{3}}$ are reinforced by whiskers of $\text{SiC}$ to form hybrid materials such as ${\text{Al}}_{\text{2}}{\text{O}}_{\text{3}}\text{/SiC}$ also known as ceramic composites.
