This white solid is the principal precursor for the manufacture of beryllium metal. This white solid is the principal precursor for the manufacture of beryllium metal. Surface modification of luminescent Ln(III) fluoride core-shell nanoparticles with acetyl salicylic acid (aspirin) - synthesis, spectroscopic and in vitro hemocompatibility studies. In protein crystallography it is used as a mimic of phosphate. : 7787-49-7. Congratulations on this excellent venture… what a great idea! © ILO and WHO 2017. © 1998-2020 American Elements. In its elemental form, beryllium has a gray metallic appearance. This white solid is the principal precursor for the manufacture of beryllium metal. Rinse skin with plenty of water or shower. Denser than water. Exposure could cause death. Beryllium Fluoride is a highly water soluble Beryllium source for use in oxygen-sensitive applications, such as metal production. (L24, L27), Once in the body, beryllium acts as a hapten and interacts with human leucocyte antigen (HLA) DP presenting cells in the lungs, becoming physically associated with a major histocompatability (MHC) class II molecule. 'Molecules' of liquid beryllium fluoride have a fluctuating tetrahedral structure. Melting point: 545 ℃ Boiling point 1175 ℃ Categories: Rare Light Metals Compounds. Holleman, A. F.; Wiberg, E. "Inorganic Chemistry" Academic Press: San Diego, 2001. Not combustible. The resulting inflammatory response is a cell-mediated process orchestrated by cytokines and results in the formation of (usually pulmonary) granulomas. See 50 Federal Register 13456 (April 4, 1985). Other name: Beryllium difluoride. The substance may cause long-term effects in the aquatic environment. Have questions or comments? The origin of the name Beryllium comes from the Greek word "beryllos," meaning beryl. Use fine water spray. INHALATION: move to fresh air; chest x-ray should be taken immediately to detect pneumonitis, if exposure has been severe. Beryllium was discovered by Louis Nicolas Vauquelin in 1797 and first isolated by Friedrich Wöhler and Antoine Bussy in 1828. Fluorine is a Block P, Group 17, Period 2 element. Wear face shield or eye protection in combination with breathing protection. Then store and dispose of according to local regulations. CAS no. See more Beryllium products. UN Hazard Class: 6.1; UN Pack Group: II, Prepared by an international group of experts on behalf of ILO and WHO, P260-P301+P310-P305+P351+P338-P320-P405-P501. Structural Design of Two Fluorine-Beryllium Borates BaMBe2(BO3)2F2 (M = Mg, Ca) Containing Flexible Two-Dimensional [Be3B3O6F3]∞ Single Layers without Structural Instability Problems. Laboured breathing. Its structure resembles that of quartz, but BeF 2 is highly soluble in water. diagnose or cure any conditions, but is for informational and educational purposes First rinse with plenty of water for several minutes (remove contact lenses if easily possible), then refer for medical attention. Effects of long-term or repeated exposure As a gas it adopts a linear triatomic structure and in the liquid state a fluctuating tetrahedral structure. Beryllium is a relatively rare element in the earth's crust it can be found in minerals such as bertrandite, chrysoberyl, phenakite, and beryl, its most common source for commercial production. In the solid state it exists as a glass, with four-coordinate Be2+ tetrahedral centres and two-coordinate fluoride centres. Shortness of breath. Beryllium's toxicity may be controlled by the iron-storage protein ferritin, which sequesters beryllium by binding it and preventing it from interacting with other enzymes. Once in the body, beryllium acts as a hapten and interacts with human leucocyte antigen (HLA) DP presenting cells in the lungs, becoming physically associated with a major histocompatability (MHC) class II molecule. This white solid is the principal precursor for the manufacture of beryllium metal. Cough. The processing of beryllium ores generates impure Be(OH)2. Control pieces which had not been fluorinated were given similar immersion.

Beryllium fluoride is the inorganic compound with the formula BeF 2. Preparation and characterization of novel green synthesized iron-aluminum nanocomposite and studying its efficiency in fluoride removal. In its elemental form, CAS 7782-41-4, fluorine gas has a pale yellow appearance. It reacts with water to form hydrofluoric acid, a source of fluoride ions. Hydrofluoric acid can cause severe chemical burns and is one of the few materials that can etch glass.

IDLH: 4 mg/m3 As Be; A potential occupational carcinogen. Beryllium fluoride . Half-upright position. The fluorine atom has a covalent radius of 64 pm and its Van der Waals radius is 135 pm. Beryllium fluoride is the inorganic compound with the formula BeF2. For the static tests the strips were immersed in either distilled or tap water. Its structure resembles that of quartz, but BeF2 is highly soluble in water. Ingestion causes fatigue, weakness, loss of appetite. [citation needed], Beryllium fluoride is used in biochemistry, particularly protein crystallography as a mimic of phosphate.

Boiling point: 1175°C Melting point: 555°C Density: 2,0 g/cm³Solubility in water: very good. See Notes. The increased toxicity of beryllium in the presence of fluoride has been noted as early as 1949. (USCG, 1999), Any dramatic weight loss should be considered as possible first indication of beryllium disease.
