A stable blister free flexible graphite is formed in accordance with the present invention by performing two chemical reactions including a first step of high temperature heat treatment which converts the active carbon surface from hydrophilic to hydrophobic and generates active surface sites and a second step of exposing the heat treated graphite to a stabilizing reagent for stabilizing the active sites generated by the first step of high temperature heat treatment.

Stable blister free flexible graphite and method

A room temperature setting carbonaceous cement comprising a solid carbonaceous material, a catalyst, a liquid carbonizable component, and copper particles, which when treated with the catalyst will provide a carbon yield of at least 40% for the liquid component at an elevated baking temperature and possess increased flexural strength at elevated temperatures and reduced electrical resistance.

Room temperature setting carbonaceous cement with increased electrical

Particles of intercalated graphite are formed by treating graphite particles with an intercalant and contacting the graphite particles with an organic molecule having C.sub.8 -C.sub.30 carbon atoms and a polar end functional group.

Low surface acid intercalated graphite and method

A halogenated or sulfonated active carbon which has a high storage capacity for methane is provided from selected halogens in elemental form or solutions of such halogens or from solutions of sulfuric acid, fuming sulfuric acid, sulfur trioxide.

Method for storing methane using a halogenating agent treated activated

A room temperature setting carbonaceous cement comprising a solid carbonaceous material, a catalyst and a liquid carbonizable component, and a boron containing or phosphorus containing material, which when treated with the catalyst will possess increased oxidation resistance at elevated temperatures.

Room temperature setting carbonaceous cement with increased oxidation

A room temperature setting carbonaceous cement comprising a solid carbonaceous material, a catalyst and a liquid carbonizable component which when treated with the catalyst will provide a carbon yield of at least 40% at an elevated baking temperature and possess a flexural strength which is above at least 750 psi at room temperature and at said elevated temperature.
