How to obtain silicon ingots of 10-15cm diameter?

How to obtain silicon ingots of 10-15cm diameter? Correct Answer By crystal pulling process

During crystal pulling process, the seed crystal and the crucible rotate in opposite direction, in order to produce ingots of circular cross section (diameter of 10/15cm normally obtained).

S1: Production of coins starts with the buying of unmixed metals and their testing by the Assay Department.
P: These ingots are reheated until the temperature is hot enough for hot rolling.
Q: During this stage, the ingots pass through a series of rollers until they form long, thin sheets which are the thickness of a coin.
R: From these thin strips, blank discs are punched.
S: Then the metals are alloyed in oil - fired or electric arc furnaces, and cast into ingots 40 cm wide, 15 cm thick and 6 m long.
S6: The blanks are heated to soften them, then rolled so that the rim is raised and are stamped with the design of the coin.
