Abstract: Ceramic foundry media is provided. The ceramic foundry media have a size of about 80 mesh to about 10 mesh, an average largest pore size of less than about 20 microns, and a surface roughness of less than about 4 microns. The ceramic foundry media are formed by drip casting. A slurry of finely divided particles is flowed through nozzles and formed into droplets under the influence of vibration. Uniform sized, smooth surface, spherical green particles are formed. The green particles are dried and sintered to form the foundry media.

Abstract: Methods and systems for infusing ceramic proppant and infused ceramic proppant obtained therefrom are provided. The method can include introducing ceramic proppant and a chemical treatment agent to a mixing vessel, mixing the ceramic proppant and the chemical treatment agent in the mixing vessel to provide a mixture, introducing microwave energy to the mixing vessel to heat the mixture to a temperature sufficient to produce infused ceramic proppant containing at least a portion of the chemical treatment agent, and withdrawing the infused ceramic proppant from the mixing vessel.

Abstract: A high density specialty fuel for propelling limited volume ramjet and turbojet missile systems comprising a blend of at least 70 weight percent of exotetrahydrodicyclopentadiene and a correspondingly minor amount of a combination of a mixture of C.sub.5 -C.sub.7 alkanes and/or cycloalkanes and hydrogenated dimers of norbornadiene.

Abstract: A high density fuel composition having low temperature operational capability for propelling turbo-jet, limited volume missile systems consisting essentially of at least 95 weight percent exo-tetrahydrodicyclopentadiene (JP-10) and a correspondingly minor amount of a C.sub.3 -C.sub.7 saturated hydrocarbon.

Abstract: Method for effecting the formation of co-trimers of cyclopentadiene and methylcyclopentadiene whereby a mixture of the dimers of said dienes is heated in the presence of an inert solvent. The foregoing method is implemented to provide a high energy fuel by substantially completely hydrogenating the resultant trimerization product.

Abstract: A method for converting endo-tetrahydrodicyclopentadiene to the corresponding exo isomeric form which is advantageously carried out in the presence of aluminum chloride catalyst and the spent nickel hydrogenation catalyst utilized in hydrogenating an endo dimer of cyclopentadiene to provide said tetrahydro derivative thereof.
