The expanded graphite can be used to make graphite foil or used directly as a "hot top" compound to insulate molten metal in a ladle or red-hot steel ingots and decrease heat loss, or as firestops fitted around a fire door or in sheet metal collars surrounding plastic pipe (during a fire, the graphite expands and chars to resist fire ...
Brass rubbings are created by laying a sheet of paper on top of a brass (then called "latten" - a zinc-copper alloy produced via the obsolete calamine brass process) and rubbing the paper with graphite, wax, or chalk, a process similar to rubbing a pencil over a piece of paper placed on top of a coin.
Using paper-making techniques on dispersed, oxidized and chemically processed graphite in water, monolayer flakes form a single sheet and create strong bonds. These sheets, called graphene oxide paper, have a measured tensile modulus of 32 GPa. [8] The chemical property of graphite oxide is related to the functional groups attached to graphene ...
Stone rubbing at the Vietnam Veterans Memorial A National Park Service volunteer kneels and uses paper and a graphite stick to create a rubbing of a name from the Vietnam Veterans Memorial. Stone rubbing is the practice of creating an image of surface features of a stone on paper. The image records features such as natural textures, inscribed ...
To produce expandable graphite, natural graphite flakes are treated in a bath of acid and oxidizing agent.Usually used oxidizing agents are hydrogen peroxide, potassium permanganate or chromic acid. Concentrated sulphuric acid or nitric acid are usually used as the compound to be incorporated, with the reaction taking place at temperatures of ...
Try using graphite transfer paper, a great tool for speeding up your art-making process. It works similarly to carbon paper but is made specifically for artists and designers. While carbon paper ...
