pure metals as biomaterial?
344252
Some of the commonly used bio materials\n\n1.Synthetic materials currently in use include metal alloys, ceramics, and polymers. \n2.Metals :\na. used for load-bearing implants such hip and knee prostheses, and wires, pins, screws for fracture fixation, and also cvascular stents.\nb.pure metals have been used, but alloys offer advantages in strength nd corrosion-resistance.\nc.three major alloys include stainless steel, cobalt-chromium-molybdenum alloys, and titanium alloys\nd.Selection criteria should include biocompatibility, appropriate mechanical properties, corrosion, and cost.\n\nPS:Common metals used in implants—either as pure elements or as alloys (mixture of metals)—include titanium, platinum, iridium, gold, iron (as stainless steel alloy), vanadium, cobalt, aluminum (ceramic) and zirconium (ceramic).  The advantage of alloys over metals is that the properties of the material can be fine-tuned to its application needs. Changing the elements and their concentrations present in the alloy leads to stronger, more flexible materials.\n\nFound a great site. Definitely go through it.\nhttp://biomed.tamu.edu/biomaterials/Metals.htm

Ok, you have lots of concepts.  1st, alloys are mixtures of metals, not a metal.  Second, you listed a bunch of different kinds of strength.  Stainless steel is stronger than titanium alloys for some applications.  Titanium has a SLIGHTLY higher heat capacity.  Alluminum alloys are fairly strong as well, but it's strength by weight, not strength by volume, which is what engineers need.  Not only that, but alot of metal alloys are "strong" to the point of unusable because they're not able to be shaped.

Not clear what you are asking.\n\nIf you are asking if any elements exist as pure elements, not in any compounds, the answer is "no".\n\nBut there are quite a few elements that make up the human body in various proportions.  Carbon, Hydrogen, Oxygen, Sodium, Potassium, Chlorine, Nitrogen, Sulfur, Phosphorus, Iron, Magnesium, Calcium make up a good bit of your body.  But it is how they are combined that is important.

Just how "pure" do you want it?\nTo what purpose do you intend to use it?  Perhaps if we knew this, we might be able to advise on what types of impurities would be considered acceptable for your application.\n\nThere are numerous inexpensive and easily accessible sources of lead available, but they all contain some degree of impurities.\n\nIf you want ultra pure lead, your best bet (although it will cost you) will be to buy it through a chemical supplier...if they will sell it to you as an individual.\n\nAnother option would be to chemically extract it from lead containing substances.\nLead is not exactly the most reactive metal out there, so it shouldn't be too hard to device a chemical reaction to extract it from a Pb compound.\nFor example, using soluble Lead Nitrate, out could precipitate out Lead metal using a more reactive pure metal.  This process might not be ideal for your particular application, but if you look around and do a bit of research, you might find something acceptable.

It is a very pure conductive metal. More pure than gold. Indeed.

You would complete dissolve it in strong acids and then separate the metals by qualitative analysis techniques.  Not simple and very expensive.

Our body require metals ,yes the same metals that are  mentioned in the periodic table. But attention is to be paid towards the quantity and form. For example our body needs iron  ( Fe)  for the haemoglobin formation. It is the same iron that forms a nail. But you can not consume a nail . It has huge quantity of iron and we can’t digest it. Instead it should enter our body through leafy vegetables. \nMost of them are required in very small quantity or trace quantity . We cannot lose sight of this fact.

it would be Covalentic ofcourse...\n\nIonic is usually when  Metal is reacting with non metal...\n\nin this case , both are not metals so it would be covalentic

There is a HUGE amount of infomation on metallurgy out there, but if you want an interesting search, try searching out why the HUBBLE Space Telescope failed - there was some deformed metal and the reason the optics tests passed before launch is an interesting story about materials, optics and people.\n\nI'm a metallurgist, and of all the exotic materials it turns out steel has the greatest range of properties (from annealed iron all the way up to ball bearing steel and stainless).  Titanium is interesting stuff (good for corrosion and medium temps (500°F-1000°F), but aluminum can have the highest density-to-strength ratio.  Research on how tungsten filaments are made is interesting too.  \n\nMark Twain said that a metallurgy student would learn more making his own pocket knife by digging the ore out of the ground, refining it into steel, and fabricating the knife than he would by book learning - do you have a passion you're particularly interesting in?  Learning about something you're interested in is effortless.\n\nAnother optics subject of interest is what is currently going on in semiconductor photolithography - they are reaching the limits of what can be done with light and refractive materials (CaF lenses) and immersion lithography (see link below).

Pure copper has a certain crystal structure as does pure tin.  Bronze will have a different crystal structure, the exact form of which will depend on the ratio of copper and tin.  (I am treating this as a general scenario, there is a chance that the crystal structure of copper and tin takes the same form - but this would be coincidental; and by chance/coincidence I don't mean theory doesn't define them - i just don't know crystal theory all that well)

use a potato and two different metals as electrodes. The link will help you, do your own homework, or web searching atleast! it was the second link in google for g** sake!

The only way I've heard of to obtain pure sodium metal is by electrolysis of NaCl.  Basically, place the salt solution between two electrodes (Na+ attracted to anode, Cl- attracted to cathode).\n\nPure Na is extremely reactive, though.  It is very difficult to store, as any exposure to air will cause almost instant oxidation of the surface (formation of Na2O).  There is also very little commercial use for pure Na.  There are many, many commercially viable sodium compounds, but pure sodium is rarely useful.

Tungsten is a fairly cheap metal (compared to the precious metals) which is very dense, has one of the highest melting points of all metals, and is resistant to acids (though not as resistant as gold or platinum)

Because it's a reactive form of metal and can easily form compounds. You wouldn't want a material in your body that's reactive otherwise you will be looking for more trouble.

"Redox" metals have more than one oxidation state.  e.g. Fe2+/Fe3+ or Cu1+/Cu2+.  Zn and Ca only occur in biological systems in the 2+ state (therefore they cannot redox cycle).
