摘要： A process for 3D printing articles made of carbon or graphite includes producing a flowable polymeric mixture from a UV permeable and polymerizable polymer or cellulose and a UV crosslinkable resin, admixing the polymeric mixture with sugar and/or cellulose until the mixture has a consistency such that it can be filled into a 3D printer and processed thereby, homogenizing the mixture at room temperature or elevated temperature, filling a 3D printer with the mixture, layerwise printing a shaped article with simultaneous exposure to UV radiation for layerwise crosslinking of the UV crosslinkable resin, cleaning the shaped article, introducing the UV precured shaped article into a furnace and stabilizing the UV precured shaped article in air at a predetermined stabilizing temperature until all volatile constituents have outgassed from the prefabricated shaped article and subsequently high temperature treating the shaped article for carbonization or graphitization in a furnace under protective gas.

摘要： A metallurgical vessel structure and method is provided for producing low-impurity Magnesia-Carbon reclaimed aggregate suitable for reuse in the production of high purity Magnesia-Carbon refractory. A metallurgical vessel is assembled with a non-reactive or chemically similar backup lining. The entire height of the working lining wall is Magnesia-Carbon brick suitable for reuse. The working lining is exposed to a metal making high temperature process, and the working lining is sequentially demolished. Due to the assembly of vessel, metallurgical practice, and ease of demolishing the vessel, there is little to no need for sorting, such that the used Magnesia-Carbon brick are easily converted into low impurity Magnesia-Carbon reclaimed aggregate. A refractory composed of low-impurity Magnesia aggregate reclaimed from the method is also contemplated.

摘要： A method for producing microencapsulated fuel pebble fuel more rapidly and with a matrix that engenders added safety attributes. The method includes coating fuel particles with ceramic powder; placing the coated fuel particles in a first die; applying a first current and a first pressure to the first die so as to form a fuel pebble by direct current sintering. The method may further include removing the fuel pebble from the first die and placing the fuel pebble within a bed of non-fueled matrix ceramic in a second die; and applying a second current and a second pressure to the second die so as to form a composite fuel pebble.

摘要： A technique of forming a carbon-carbon composite that includes infiltrating a preform comprising carbon fibers or carbon-precursor fibers with a pitch and pyrolyzing the pitch using a controlled pressure and temperature ramp rate to control a growth of optical textures as the pitch is pyrolyzed to a coke matrix. Pyrolyzing the pitch may include initiating pyrolysis of at least some of the pitch at a first pressure less than about 2000 psi and a first temperature ramp rate between about 5° C./hr and about 50° C./hr to a first target temperature, and pyrolyzing at least some of the pitch at a second pressure greater than 2000 psi and a second temperature ramp rate between about 5° C./hr and about 50° C./hr to a second target temperature, where the second target temperature is greater than the first target temperature.
