GERMANIUM (GE)
Germanium is used in the semiconductor industry in the form of polished
wafers.
Germanium crystals are grown in rods up to 1-3/8 in. (3.49 cm) in diameter
for use in making transistor wafers. High-purity crystals are used for both P
and N semiconductors. They are easier to purify and have a lower melting
point than other semiconductors, specifically silicon.

HEALTH WARNING
Germanium is generally considered to be low in toxicity. Its NFPA Rating
for Health is 0 on a scale of 0 - 4.
INGESTION
If ingestion occurs, obtain immediate medical attention. The following
