Chapter 15, Problem 15.24P

Interpretation Introduction

(a)

Interpretation:

The use of uniaxial compaction and sintering should be explained.

Concept Introduction:

Sintering is a process where heat or pressure is applied to compact and form solid mass without melting it. It happens naturally in mineral deposits or used as manufacturing plastics and other materials. There are sintering parameters as follows:

1. High-density compact nanomaterials.
2. Microwave sintering, etc.

Interpretation Introduction

(b)

Interpretation:

The use of hot pressing should be explained.

Concept Introduction:

Hot pressing is a process of high pressure, low strain rate metallurgical process for forming a powder or compacting powder at high temperature to induce sintering and creeping process.

The process is carried out by simultaneous action of pressure and heat.

This technique is used to produce metal and ceramic-based composites that are simple and versatile.

Interpretation Introduction

(c)

Interpretation:

The use of HIP should be determined.

Concept Introduction:

HIP stands for hot isostatic pressing process.

It is the manufacturing process used to reduce the porosity of metals and improve the density of ceramics materials. By achieving these properties, it eventually improves the materials mechanical properties and workability.It is the simultaneous application of heat and pressure to metals and other materials for the desired amount of time.

Interpretation Introduction

(d)

Interpretation:

The use of tape casting should be determined.

Concept Introduction:

The process of making ceramic tapes from ceramics slurry is called as tape casting. It is a type of casting process also called doctor blading and knife coating. The ceramic slurry is cast in a thin layer onto a flat surface and later dried and sintered.

Tape casting was famous as mass produce capacitor methods.
