Substances indicated, in 2009, as being intended to be registered by at least one company in the EEA. Original file ‎ (SVG file, nominally 242 × 51 pixels, file size: 8 KB). barium azide (dry o r containing less t han 50% water) diazidobarium. Please no talk of safety, how to make, or questions about its use. 2Na N 3 → 2Na+3 N 2. It never occurs in nature in its pure form due to its reactivity with air, but combines with other chemicals such as sulfur or carbon and oxygen to form barium compounds that may be found as minerals. Can be used to make azides of magnesium (but its hydrolytic tendency frustrated efforts to isolate it), sodium, potassium, lithium, rubidiumand zincwith their respective sulfates. Barium azide can be used to make azides of lithium, magnesium, potassium, rubidium, sodium and zinc via substitution with their respective sulfates. The typical flashed getter used in small vacuum tubes (seen in 12AX7 tube, top) consists of a ring-shaped structure made from a long strip of nickel, which is folded into a long, narrow trough, filled with a mixture of barium azide and powdered glass, and then folded into the closed ring shape. Can burn very vigorously producing toxic oxides of nitrogen. The photolysis of barium and strontium azides 651 Three temperature ranges were found with changes in activation energy at -4and + 50 The molecularities were the same as for barium azide in the relative tem- perature ranges except for the low temperature induction period and for all periods in the high temperature range. Here you can find all of the regulations and regulatory lists in which this substance appears, according to the data available to ECHA. Contents. In manufacture, during vacuum pumping, the anode would be heated to vapourize the azide. It is less sensitive to mechanical shock than lead azide. Can be used to make azides of magnesium (but its hydrolytic tendency frustrated efforts to isolate it), sodium, potassium, lithium, rubidium and zinc with their respective sulfates.[4]. BARIUM AZIDE, WETTED WITH NOT LESS THAN 50% WATER is a suspension or slurry of of an unstable solid in sufficient water to allow safe shipping and handling. We assume you are converting between grams Barium Azide and mole. This page was last modified on 1 January 2016, at 18:46. Wetting reduces its sensitivity of shock. Dangerous Goods List (ADR, Chap. Barium azide is an inorganic azide with the formula Ba(N3)2. 2 Names and Identifiers Expand this section. It can also be used as a source for high pure nitrogen by heating: Ba(N 3) 2 → Ba + 3N 2. I will post a thread in the chemistry section after I have done experimenting with it. Product name : Barium Oxide CAS-No. Nitrogen, nonmetallic element of Group 15 [Va] of the periodic table. Barium azide can be used to make azides of magnesium, sodium, potassium, lithium, rubidium and zinc with their respective sulfates. Close Find out more on how we use cookies. Reasons are given later for the assumption that correct relationship has the form p = C(t -y), (2) where y is a slow-growth correction, or the time taken for the nucleus to grow to the critical size for normal growth. Understanding POPs Proposals for new POPs The barium would react with the oxide on the filament to form a barium oxide layer on the Tungsten. The alkali metals react with oxygen to form several different compounds: suboxides, oxides, peroxides, superoxides, and ozonides. Substances listed in the EINECS, ELINCS, or NLP inventories. Sodium azide is used as a chemical preservative in hospitals and laboratories. BuyersGuideChem provides reliable information about Barium azide (18810-58-7) like chemical properties, structure, melting point molecular formula, molecular weight, physical properties, toxicity information. You can view more details on each measurement unit: molecular weight of Barium Azide or mol The molecular formula for Barium Azide is BaN6. Sodium azide is used in agriculture (farming) for pest control. Barium azide, wetted, is a substance of Class 4.1. The symbol of this chemical element is N and its atomic numberis 7. 3.2, Table A), Directive 2008/68/EC, last amended by Regulation 2019/1243/EU, 25 July 2019, EU. [DBID] Experimental data; Predicted - ACD/Labs; Manufacturing of N 2. Its atomic number is 7 and it is denoted by the symbol ‘N’ in the periodic table. Can be used to make azides of magnesium (but its hydrolytic tendency frustrated efforts to isolate it), sodium, potassium, lithium, rubidium and zinc with their respective sulfates. In one case, sodium azide was poured into a drain, where it exploded and the toxic gas was inhaled (breathed in). Can burn very vigorously producing toxic oxides of nitrogen. BPR regulation aims to improve the functioning of the biocidal products market in the EU, while ensuring a high level of protection for humans and the environment. The per substance REACH registration status is being calculated and will be made available as soon as possible. Supplier Login Liste your products Your advantage. At high temperature the vapour would decompose to form barium and nitrogen. May explode if allowed to dry out and then heated or shocked. BARIUM AZIDE, [DRY OR WETTED WITH < 50 % WATER] may decompose explosively when subjected to shock or heat. It has an atomic symbol Ba, atomic number 56, and atomic weight 138. This Directive establishes rules for the safe transport of dangerous goods between EU countries by road, rail, and waterway. The nuclei are formed at a rate proportional to the square of the time and, when large, grow at a constant rate with an activation energy of 25 kcal./mole. Understanding POPs Proposals for new POPs Very pure nitrogen can be obtained by heating sodium or barium azide. 1 mole is equal to 1 moles Barium Azide, or 221.3672 grams.
