Chapter 24, Problem 43R

To determine

To compare: Alloys and ceramics.

Explanation of Solution

Introduction:

Alloys are created from a mixture of two or more metals. Ceramics are solids made from dried clay or other similar materials.

Differences between alloys and ceramics are:

1. Alloys are created from a mixture of two or more metals. For example: Brass is created by combining copper and zinc. Ceramics are solids made from clay, feldspar or silica.
2. Alloys are manufactured by combining two or more metals in the liquid form and cooling them after. Ceramics are manufactured by heating the raw materials at very high temperatures.
3. Alloys are not brittle, that is, they do not break when dropped. Ceramics can be brittle, that is, they can break if dropped.

Conclusion:

Both alloys and ceramics have been used since ancient times.
