Amorphous silicon is form of silicon, the second most abundantly occurring
natural element on Earth.

Yet claim 14 of US Patent No. 4451538 , which claims amorphous silicon that is
made a certain way, was allowed:
1. A process of forming amorphous silicon from a glow discharge comprising the
steps of:
providing a gas atmosphere containing H.sub.2 and SiH.sub.4 in a ratio of at
least approximately 9 to 1, at a flow rate of no more than 10.sup.-3 SCCM per
cubic centimeter;
establishing a glow discharge by discharging electrical power through the
atmosphere at a density of no more than 0.08 watts per square centimeter; and
exposing a substrate to the glow discharge to deposit amorphous Si:H thereon.
11. The process of claim 1 wherein:
the gas atmosphere includes a preselected dopant.
12. The process of claim 11 wherein:
the dopant comprises B.sub.2 H.sub.6.
13. The process of claim 12 wherein:
the concentration of B.sub.2 H.sub.6 in the gas atmosphere is at least
approximately 500 parts per million.
14. The product by the process of claim 13
which has an optical gap of at least 1.85 electron volts and a dark conductivity
of at least approximately 10.sup.-6 inverse ohm-centimeters.

Accordingly, If Aluminum alone was not known or not naturally occurring, or if
you invented a new way to separate the oxygen from known Aluminum Oxide to
produce Aluminum, then you could have gotten a patent for Aluminum or at least
for Aluminum that was produced by your new way.
