Question

In powder metallurgy, how is the powder for brittle materials prepared?

(a) Pulverization

(b) Atomization

(c) Electrolysis

(d) Fusion

I have been asked this question in an online quiz.

This is a very interesting question from Sintering and Compacting, Pig Iron and its Manufacture in section Testing of Materials, Foundry & Powder Metallurgy of Engineering Material & Metallurgy

Answer 1

Correct choice is (a) Pulverization

For explanation I would say: Pulverization is a process of preparation of powders for metallurgical operations. It can be done using a variety of machines like hammering, counter-rotating plates, or ball milling. Depending on the type of metal and the grain size, an appropriate pulverization technique can be chosen.
