FAQ

When Aluminium nitrate is heated , i got yellow amorphous solid which did not not melt on further heating. What compound is that?
l would say you have mostly aluminum oxide as a product which probably contains some Nitrogen dioxide gas, a second product of the decomposition of aluminum nitrate. If I were you I would not heat nitrate salts as they can explode upon heating. they also need to be kept away from any kind of reducing agent such as powdered metals, or any fuels, reactions can be violent.
Does anyone know why Mercury -(Thimerosal) is used in Flu Vaccinations and where Mercuryisnot used Aluminium in other vaccines ? While these are known to be toxic metals, can these cause headaches, severe hot burning heads and or Sinusitus ?
Thimerosal is not the same as mercury. It's a mercury-based preservative which to prevent the growth of germs, bacteria and fungi, that can contaminate them. It's used in seasonal flu vaccine because the vaccine is produced in large quantities and often in multi-dose vials. Thimerosal helps safeguard against possible contamination of the vial once it is opened. The aluminum in vaccines is aluminum hydroxide, aluminum phosphate, alum (potassium aluminum sulfate), or mixed aluminum salts. They're an adjuvant added to enhance the immune response in the vaccinated individual. Whether or not something is toxic has to do with how much a person receives not the substance itself. People can die from drinking too much water, but we don't go around calling water toxic. The amount of mercury or aluminum in vaccines is so small that it's not toxic. You ingest more mercury by eating fish and a baby ingest more aluminum in breast milk than they get in a vaccine. So if mercury and aluminum caused head aches, severe hot burning heads or sinusitis in a person, that person would have a lot more to worry about than vaccines since they would be exposed to those things in so many other ways.
There are several methods of surface etching aluminum sheets, including chemical etching, electrochemical etching, mechanical etching, and laser etching. Chemical etching involves the use of corrosive chemicals to selectively remove the surface material, creating a desired pattern or design. Electrochemical etching uses an electrical current to dissolve the surface of the aluminum sheet, also creating a pattern. Mechanical etching involves physically abrading the surface using tools or abrasive materials. Laser etching utilizes a high-powered laser beam to selectively remove the aluminum material, creating precise and detailed patterns.
The thermal conductivity of aluminum sheets is approximately 205-230 watts per meter-kelvin.
I have a lot of old aluminum cake pans, coffee pots, pots and pans and various old nuts and bolts made of aluminum. Would it be worth it to scrap them? They really aren't usable for cooking anymore. They are clean.
Aluminum is currently scrap priced at eighty cents per pound. If you have enough to justify the gasoline to go to a scrap yard, yes it is worth it. Your scrap will end up in Japan rather than in a landfill.
Aluminum sheets possess exceptional thermal conductivity characteristics. With a thermal conductivity of approximately 237 Watts per meter-Kelvin (W/mK), aluminum surpasses other commonly used metals like steel or copper in this aspect. Consequently, aluminum sheets excel in the efficient transfer of heat over their surface. Due to its high thermal conductivity, aluminum can swiftly conduct and distribute heat, making it an optimal choice for applications that demand efficient heat transfer, including heat exchangers, cooling systems, and heat sinks. Moreover, aluminum's lightweight nature and resistance to corrosion further enhance its popularity in thermal management applications. In summary, aluminum sheets exhibit outstanding thermal conductivity properties, positioning them as the preferred material in industries that prioritize efficient heat transfer.
Do these frames rust? For example here is a link. But I am genuinely curious because in swimming pools, the hand rails going into the swimming pool have the same finish as this bike frame and they have white corrosion marks. Thank you in advanced
Best thing you can do for a polished Aluminium frame, is to firstly polish it, wipe down with a wax and grease remover, and then spray with a 2 pak clear coat. You will save yourself many years of polishing in the future.
Certainly, the construction industry can make effective use of aluminum sheets. Aluminum proves to be a highly adaptable and lightweight material, offering numerous advantages for construction purposes. Its resistance to corrosion makes it especially suitable for outdoor structures and buildings. Roofing, siding, window frames, doors, and other architectural components often incorporate aluminum sheets. Moreover, aluminum's exceptional strength-to-weight ratio enables the creation of sturdy and efficient structures. Its malleability also facilitates easy fabrication and shaping into various forms, allowing for imaginative and groundbreaking designs in construction projects. Overall, aluminum sheets remain a widely favored choice in the construction industry due to their enduring nature, adaptability, and aesthetic appeal.
