FAQ
Frequently Asked Questions
Yes, in its processed forms (like dust or fumes), beryllium is a toxic substance that can cause a serious, incurable lung disease called chronic beryllium disease (CBD). Solid metal is safe to handle with intact skin.
Beryllium is not found free in nature. It occurs in minerals like beryl (emerald, aquamarine) and bertrandite. It is mined and extracted for industrial use.
Its main uses are as a hardening agent in alloys (especially beryllium copper), in windows for X-ray and radiation equipment due to its transparency to certain radiation, and in aerospace and defence components for its lightness and rigidity.
It was once called 'glucinium' (symbol Gl) from the Greek 'glykys' meaning sweet, as some of its compounds have a sweet taste. This name is obsolete.
