Welcome to the first weekly feature of a
countdown of the 10 most at risk elements as according to the BGS. Click here
for a recap of the scoring system.
RANKING:
10
ELEMENT
NAME AND SYMBOL:
Beryllium
(Be)
RELATIVE
SUPPLY RISK INDEX:
8.1
WHY?:
Only
three countries produce Be (and the USA alone mines 90% of total supplies) and
so the risk here is mainly a political one
LEADING
PRODUCER:
USA
TOP RESERVE HOLDER:
UNKOWN
WHY
THE DEMAND?:
Beryllium
is a fairly rare element in the Earth due to it only being stable in minerals (in
combination with other elements). Its concentration in the crust is of just 2-6ppm.
Beryllium
is very harmful to humans if not correctly handled and so doesn’t have many
applications. It is however used to alloy with other metals due to its extreme hardness,
and can then be used in many aircraft components due to it being strong yet
lightweight. Another novel use is in x-ray tube radiation windows, due to Be
being a very low absorber of x-rays. Most Beryllium mined in the US is used by
the military, although what they use it for is guarded.
