Czochralski (Pulling) Process

 

Czochralski (Pulling) Process

Inamori [Japan] (red, orange and red star), Novosibirsk [Russia] (red) and others (red, blue and colourless).

1.   Extremely fine and narrow curved growth lines (curved striae), which may be concentric.

2.   Gas bubbles of various sizes, shapes and orientations.

3.   Faint ‘smoke-like’ or ‘rain-like’ wisps of tiny particles, probably repre- senting remnants of a flux used to aid melting during growth.

4.   Small unidentified black prismatic crystals in groups (Inamori).

5.   Extremely fine exsolved clouds of what may be rutile silk in the red star material (Inamori).
