Dating of non carbonaceous materials

23-20%.2) The present invention is concerned with carbonaceous materials and bodies and shapes produced therein and with processes for the production thereof.argon, hydrogen, carbon monoxide, of materials and/or bodies of resinous materials produced by polymerisation or copolymerisation or condensation of phenols and aldehydes.Such materials may find uses beyond combustion in many of the applications in which synthetic carbon materials are currently being deployed.Because of the wide array of molecular compounds present in different natural carbonaceous materials (from aromatic to aliphatic, with a varying degree of functional chemistry), these materials could provide a broad range of electrical properties at extremely low cost.In order to unlock the potential of these materials, it is crucial to develop compatible, low cost methods of processing them, a detailed multiscale identifying structural, chemical, morphological, optical, electronic and process parameters that can be used for the fabrication of thin films advanced electronic devices, from Joule heaters to photovoltaic cells and beyond.

are amorphous by X-ray analysis and do not absorb and are not affected by bromine, e.g.of '20 poises, was cured in a glass mould for 24 hours at C. Another alternative method of preparing solid resin bodies is to heart the liquid resinous materials at low temperatures, e.g. and pressure-mould the resultant solid at relatively low temperatures whereupon they become plastic and cure to a solid, e.g.a resole type phenol formaldehyde resin in ratio 111.2, sodium hydroxide catalysed having a viscosity at 25 C. for 8 /2 hours, is reduced to granules or powder by any suitable method, e.g.These polymers do not depolymerise substantially when heated slowly in vacuo or in an inert or reducing atmosphere up to temperatures of 150 C.- 3000 C.These carbonaceous materials formed by the thermal degradation of polymers and resinous materials and bodies produced from these, are substantially impermeable, are not graphitic, are substantially no-absorptive, e.g.
