Question

The number of grain boundaries present in the crystal created using the Czochralski process is _____________

Answer 1

Zero.

czochralski process is for making single crystal and in single crystal there is no grain boundaries.

so answer is zero.

Answer 2

Answer:

• Investigation of rate of crystallization of metals in the year 1915 gave rise to the process of Czochralski.  
• With this process semiconductors like “germanium, silicon” etc. salts, gemstones and metals like gold, silver having single crystals are obtained by the method of “Crystal growth”.
• Since the crystals formed in this process are single hence the number of grains that are formed during this process are also zero that is single crystal having zero grain boundaries.
