1302-74-5 Usage
Description
Aluminum Oxide, also known as Alumina, is a white powder that is almost insoluble in water. It is an amphoteric substance, meaning it can react with both acids and alkalis. Aluminum Oxide occurs naturally as bauxite, corundum, and white sapphire, and is manufactured by heating aluminum hydroxide. It is characterized by its hardness, strength, and stiffness, as well as its electrical resistivity, dielectric strength, and resistance to a wide variety of chemicals.
Uses
Used in Abrasive Applications:
Aluminum Oxide is used as an abrasive for its hardness and wear resistance properties. It is commonly used in the form of corundum, which is nearly colorless when pure.
Used in Ceramics Industry:
Aluminum Oxide is used as a raw material for ceramics due to its high hardness, strength, and stiffness. It also offers excellent electrical resistivity and dielectric strength, making it suitable for various applications in the ceramics industry.
Used in Refractory Applications:
Aluminum Oxide is used in furnace linings and other refractory applications due to its high melting point and resistance to a wide variety of chemicals. It is also unaffected by air, water vapor, and sulfurous atmospheres.
Used in Chemical and Aerospace Applications:
Aluminum Oxide is used in the chemical and aerospace industries for its high hardness, close dimensional tolerance capability, and its ability to withstand extreme conditions.
Used in Electrical Insulators:
Aluminum Oxide is used as an electrical insulator due to its excellent electrical resistivity and dielectric strength.
Used in Catalysts:
Aluminum Oxide is used as a catalyst in various chemical reactions, such as the dehydration of alcohols.
Used in the Production of Aluminum Metal:
Aluminum Oxide is used in the extraction of aluminum by electrolysis, which is an essential process in the production of aluminum metal.
Used in Pigments:
Aluminum Oxide is used as a pigment in various applications due to its white color and opacity.
Used in Catalyst Carriers:
Aluminum Oxide is used as a carrier for catalysts in various chemical processes, providing a solid surface for the catalyst to be supported and active.
Potential Exposure
Most hazardous exposures to aluminum occur in smelting and refining processes. Aluminum is mostly produced by electrolysis of Al2O3 dissolved in molten cryolite (Na3AlF6). Aluminum is alloyed with copper, zinc, silicon, magnesium, manganese, and nickel; special additives may include chromium, lead, bismuth, titanium, zirconium, and vanadium. Aluminum and its alloys can be extruded or processed in rolling mills, wire works, forges, or foundries; and are used in the shipbuilding, electrical, building, aircraft, automobile, light engineering, and jewelry industries. Aluminum foil is widely used in packaging. Powdered aluminum is used in the paints and pyrotechnic industries. Alumina, emery, and corundum has been used for abrasives, refractories, and catalysts; and in the past in the first firing of china and pottery.
Shipping
UN1309 Aluminum powder, coated, Hazard Class: 4.1; Labels: 4.1-Flammable solid. UN1383 Pyrophoric metals, n.o.s. or Pyrophoric alloys, n.o.s., Hazard Class: 4.2; Labels: 4.2-Spontaneously combustible material, Technical Name Required. UN1396 Aluminum powder, uncoated, Hazard Class: 4.3; Labels: 4.3-Dangerous when wet material. NA9260 (North America) Aluminum, molten, Hazard class: 9; Labels: 9-Miscellaneous hazardous material.
Incompatibilities
Aluminum powder forms an explosive mixture with air and is a strong reducing agent that reacts violently with oxidizers, strong bases; strong acids; somehalogenated hydrocarbons; nitrates, sulfates, metal oxides and many other substances. Keep away from combustible materials.
Waste Disposal
Consult with environmental regulatory agencies for guidance on acceptable disposalpractices. Generators of waste containing this contaminant (≥100 kg/mo) must conform with EPA regulations governing storage, transportation, treatment, and waste disposal of Aluminum Oxide-Disposal in a sanitary landfill. Mixing of industrial process wastes and municipal wastes at such sites is not encouraged however. Aluminum powder may be recovered and sold as scrap. Recycling and recovery is a viable option to disposal for aluminum metal and aluminum fluoride (A-57).
Check Digit Verification of cas no
The CAS Registry Mumber 1302-74-5 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 1,3,0 and 2 respectively; the second part has 2 digits, 7 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 1302-74:
(6*1)+(5*3)+(4*0)+(3*2)+(2*7)+(1*4)=45
45 % 10 = 5
So 1302-74-5 is a valid CAS Registry Number.
