2. Expandable graphite - Wikipedia

   en.wikipedia.org/wiki/Expandable_graphite

   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 ...

3. Graphite - Wikipedia

   en.wikipedia.org/wiki/Graphite

   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 ...

4. Honeycomb structure - Wikipedia

   en.wikipedia.org/wiki/Honeycomb_structure

   For the same purpose, as foundation sheets to harvest more honey, a honeycomb moulding process using a paper paste glue mixture had been patented in 1878. [9] The three basic techniques for honeycomb production that are still used today—expansion, corrugation and moulding—were already developed by 1901 for non-sandwich applications.

5. Reactive multi-layer foil - Wikipedia

   en.wikipedia.org/wiki/Reactive_multi-layer_foil

   The foil can be used as a pyrotechnic heat source, a replacement of potassium chlorate/iron pellets, for thermal batteries. It reacts faster than the conventional composition, reaches higher temperatures, and heat buffers of inert metal (e.g. steel) are needed to lower the peak temperature and prolong the heat delivery.

6. Annealed pyrolytic graphite - Wikipedia

   en.wikipedia.org/wiki/Annealed_pyrolytic_graphite

   Annealed Pyrolytic Graphite (APG), also known as Thermally Annealed Pyrolytic Graphite (TPG), [1] is a form of synthetic graphite that offers excellent in-plane thermal conductivity. As with pyrolytic carbon or pyrolytic graphite (PG), APG is also low in mass, is electrically conductive , and offers diamagnetic properties that allow it to ...

7. Sandwich-structured composite - Wikipedia

   en.wikipedia.org/wiki/Sandwich-structured_composite

   Sandwich structures can be widely used in sandwich panels, with different types such as FRP sandwich panel, aluminium composite panel, etc. FRP polyester reinforced composite honeycomb panel (sandwich panel) is made of polyester reinforced plastic, multi-axial high-strength glass fiber and PP honeycomb panel in special antiskid tread pattern ...

8. Graphite intercalation compound - Wikipedia

   en.wikipedia.org/wiki/Graphite_intercalation...

   Potassium graphite under argon in a Schlenk flask. A glass-coated magnetic stir bar is also present. One of the best studied graphite intercalation compounds, KC 8, is prepared by melting potassium over graphite powder. The potassium is absorbed into the graphite and the material changes color from black to bronze. [3]

9. Sheet moulding compound - Wikipedia

   en.wikipedia.org/wiki/Sheet_moulding_compound

   Sheet moulding compound (SMC) or sheet moulding composite is a ready to mould glass-fibre reinforced polyester material primarily used in compression moulding. [1] The sheet is provided in rolls weighing up to 1000 kg. Alternatively the resin and related materials may be mixed on site when a producer wants greater control over the chemistry and ...
