What is beryllium fluoride used for?
Beryllium Fluoride is a glassy crystal, colorless or grey solid with no odor. It is used in refining Beryllium and manufacturing Beryllium alloys, and as a chemical reagent.
What color is beryllium?
silvery-white
Beryllium is a silvery-white metal. It is relatively soft and has a low density. Beryllium is used in alloys with copper or nickel to make gyroscopes, springs, electrical contacts, spot-welding electrodes and non-sparking tools. Mixing beryllium with these metals increases their electrical and thermal conductivity.
Is beryllium toxic?
Health effects of beryllium Beryllium is not an element that is crucial for humans; in fact it is one of the most toxic chemicals we know. It is a metal that can be very harmful when humans breathe it in, because it can damage the lungs and cause pneumonia.
Is BeO toxic?
BeO is carcinogenic in powdered form and may cause a chronic allergic-type lung disease berylliosis. Once fired into solid form, it is safe to handle if not subjected to machining that generates dust.
What does beryllium and fluoride make?

What is special about beryllium?
Uniquely strong and light, beryllium is used to make cell phones, missiles and aircrafts. But workers who handle the metal need to watch out, as airborne beryllium has been known to be highly toxic.
What happens if you touch beryllium?
* Beryllium Oxide is a CARCINOGEN–HANDLE WITH EXTREME CAUTION. * Contact can cause eye irritation, redness, itching and burning. * Beryllium Oxide can irritate and burn the skin. Higher exposure may cause skin ulcers to develop.
How much is beryllium worth?
Ninety-eight-percent pure beryllium is expensive, selling from $600 to $800 per pound prior to machining, so shops must understand its machining idiosyncracies to avoid scrapping progressively expensive parts.
Is beryllium safe to handle?
* Beryllium is a CARCINOGEN–HANDLE WITH EXTREME CAUTION. * Breathing Beryllium can irritate the nose, throat and lungs. Bronchitis and/or pneumonia may occur 1-2 days after high exposure. * Eye contact can cause irritation, itching and burning.
What happens if you inhale beryllium oxide?
* Beryllium Oxide can irritate and burn the skin. * Breathing Beryllium Oxide can irritate the nose, throat and lungs causing nasal discharge, tightness in the chest, and cough.
Is beryllium fluoride soluble in water?
Beryllium fluoride is the inorganic compound with the formula BeF2. This white solid is the principal precursor for the manufacture of beryllium metal. Its structure resembles that of quartz, but BeF2 is highly soluble in water.
Is beryllium a rare earth metal?
Beryllium is not strictly a rare earth but its scarcity and versatility makes it a much sought-after metal. Known worldwide stocks amount to only a few thousand tons. The amount of beryllium metal discovered in Xinjiang is estimated to exceed 4,000 tons.
Why is beryllium special?
Despite its toxicity, the element is highly useful because of its unique qualities. For instance, it is one of the lightest metals and has one of the highest melting points among the light metals, according to the Los Alamos National Laboratory.
Is beryllium cancerous?
In addition, the International Agency for Research on Cancer (IARC) classifies beryllium as a Group 1 carcinogen (carcinogenic to humans), and the National Toxicology Program (NTP) lists beryllium as a known human carcinogen.
