(a) In the shaping process of powder produced materials, the size of the particles is an important characteristic. Name two other characteristics of particles which are of significance and describe how these characteristics affect the material.

(b) What factors determine particle size in metal powder production by chemical reaction?

(c) One method of determining particle sizes is to measure the velocity of descent when the particles are suspended in a fluid.

(i) Describe two other methods.

(ii) An experiment to determine ceramic particle sizes showed that the rate of descent when suspended in a fluid ranged from 1.2 × 10–6m s–1 to 5 × 10–6 m s–1.

The density of the material was 3800 kg m–3 and the density and viscosity of the fluid at room temperature were 1632 kg m–3 and 0.00972 Pas respectively. Calculate the range of sizes of the particles.

Powder particles can be made by various methods. The property of the prepared powders depends on various physical and geometrical parameters. In order to classify the powder one of the important characteristics is the particle size. Different techniques including descent time are used.An example is evaluated to illustrate.
