Question

What is the advantage of using Czochralski, Bridgman- Stockbarger and Verneuil method?

(a) Gives small crystals

(b) High tech apparatus

(c) Rapid growth rates

(d) Uses plasma torch

I had been asked this question in class test.

This intriguing question comes from Growth of Single Crystals topic in chapter Preparative Methods of Solid State Chemistry

Answer 1

Correct answer is (c) Rapid growth rates

The explanation: The above methods are melt growth methods which are used for the growth of crystals. Advantages of using these melt growth methods are, t gives large crystals, allows rapid growth rates, and requires very simple apparatus. While the disadvantage can be in the crystal quality which can be poor with inhomogeneities and large defect concentrations.
