differences between Teflon and Graphite?

Teflon is an organic polymer (PTFE or polytetrafluoroethylene. It  was discovered on April 6, 1938 by Dr. Roy Plunkett at the DuPont research laboratories (Jackson Laboratory in New Jersey). Plunkett was working with gases related to Freon® refrigerants when upon checking a frozen, compressed sample of tetrafluoroethylene, he and his associates discovered that the sample had polymerized spontaneously into a white, waxy solid to form polytetrafluoroethylene or PTFE. \n\nPTFE was first marketed under the DuPont Teflon ® trademark in 1945. The molecular weight of Teflon can exceed 30,000,000, making it one of the largest molecules known. The surface is so slippery, virtually nothing sticks to it or is absorbed by it. No wonder Teflon was choosen to be used on non-stick cooking pans. \n\nGraphite is a essentially a form of pure carbon, totally inorganic, and naturally occurring.

Today's pencils use graphite not lead.  Check your local Staples or other office supply store.

- The bonds between graphite layers are weaker that the bonds within graphite layers \n\nThis is how pencils work, a layer slides off by rubbing it against paper.

hi!\nGo through these links. hope you will get useful information\n\nhttp://composite.about.com/od/books/\nhttp://composite.about.com/od/referencematerials/l/aa040797.htm\nhttp://composite.about.com/library/weekly/aa051297.htm

ebay should have some sticks on there, thats where i got mune , although personally i'd go down the hardware store, get some aliminum pipe (hollow solid wold be too heavy and dangerouse) and make you'r own. this would give you the perfect size and width stick for you, it wont crack or smash like graphite and its way cheap!

The black powder is graphite.

Teflon is a long chain polymer molecule (PTFE - polytetrafluoroethylene) and so it is a lot tougher  than some other types of polymers. It is applied in coats - the bottom layer being the stickiest followed by several layers of decreasingly sticky layers...if that makes sense!\n\nBefore they apply the layers of non stick coating, the metal is treated so that is has very small lumps and pores on it which gives the teflon a better chance of sticking to the surface.

First they sandblast the pan to create a lot of microscratches on its surface. Then they spray on a coat of Teflon primer. This primer, like most primers, is thin, enabling it to flow into the the micro-scratches. The primed surface is then baked at high heat, causing the Teflon to solidify and get a reasonably secure mechanical grip. Next you spray on a finish coat and bake that. (The Teflon finish coat will stick to the Teflon primer coat just fine.)

They are different, but not that different. Almost all rackets are 90% or more graphite. Rackets that say "titanium" are still almost all graphite. Same with liquidmetal. \nLiquidmetal is a newer technology (it replaced titanium rackets in the Head line of rackets) and for many, gives players a bigger sweet spot, more stability and some added power. Head still uses Liquidmetal in their Flexpoint line, although it is not the main selling point anymore.\nEven without knowing the exact titanium racket you are looking at for $50, I would think the Liquidmetal racket would be the better choice, even at $80. Originally, Liquidmetal rackets sold for $100-200, so $80 is a good deal.

CF4 or carbon tetrafluoride has a tetrahedral structure\nthat is the carbon atom at the center of a regular tetrahedron and the F atoms at the corners\nthis is because the carbon atom is sp3 hybridised and has these four sp3 hybridised orbitals bonded with 4 F atoms which orient themselves symmetrically in space so as to balance the forces of repulsion between them and reduce energy thus givin a tetrahedral molecule

Both diamond and graphite are network solids, in which all the atoms are covalently bonded together.\n\nThey have different types of bonding though.  This gives them different properties.\n\nGraphite consists of planes of hexagons of carbon atoms.  The bond angles in the plane are 120 degrees, and every atom is in the sp2 hybridization.  The planes are only connected together through some weaker pi-bonding between the layers, so it is relatively easy for the layers to slide past each other, making graphite soft.\n\nDiamond consists of tetrahedral bonding of carbon.  All four nearest neighbors are exactly the same distance apart.  It is in the sp3 hybridization, so the bond angles are 108.5 degrees.  All the bonds are equally strong, too.  Diamond is the hardest natural substance.  The only way to cut a diamond is to use another diamond or get it to cleave along a crystal plane (in a similar manner to cleaving graphite along the plane).\n\nThe reason for forming two different compounds is thermodynamics.  Both types of bonding are possible in carbon (sp2 and sp3 hybridization) but graphite is more stable at ambient temperature and pressure.  Diamond is more stable at high temperature and pressure.

The fuel rods in a reactor are uranium-235.  Graphite is used in the control rods that slow down the reaction.

carbon more accurate cost more but as long as you don't break them which is hard to do they will last for ever wont bend unlike aluminum if you bend it..........It will never fly straight again

Lucky you, you just stuck yourself with graphite, not lead.  Hurtz, donut?

Good luck with this. A couple of searches online for LD50 of teflon show that most MSDS do not report this value and manufacturers of teflon aren't listing the value either. Quite possibly the unsafe level in humans or the LD50 isn't known.

Yes, you can use it... the HB 2 is the key.... that is telling you the hardness of the graphite and a #2 = HB2.\n\nGood luck on your test!!!!
