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.

The polycrystalline diamond includes a first volume including an interstitial material and a second volume having a leached region that includes boron and titanium. A method of fabricating a polycrystalline diamond element may include positioning a first volume of diamond particles adjacent to a substrate, the first volume of diamond particles including a material that includes a group 13 element, and positioning a second volume of diamond particles adjacent to the first volume of diamond particles such that the first volume of diamond particles is disposed between the second volume of diamond particles and the substrate, the second volume of diamond particles having a lower concentration of material including the group 13 element than the first volume of diamond particles.

摘要： A method for manufacturing composite electroceramics comprises obtaining recycled capacitors, coils, resistors, conductors circuit boards, and/or other recycled electronic components. The components may be grinded into a particles having a particle size below 2 mm, and mixed with NaCl powder or Li2MoO4 or other watersoluble ceramic powder having a particle size of 5-200 microns, in a ratio of 10-40 vol-% optionally grinded components, and 60-90 vol-% NaCl powder or Li2MoO4 or other ceramic powder. The obtained solids mixture is mixed with aqueous solution of NaCl, Li2MoO4 or said other ceramic, in a ratio of 70-90 wt-% solids mixture, and 10-30 wt-% aqueous solution. The obtained homogeneous mass is compressed in a mould for 2-10 min, in room temperature, in a pressure of 100-400 MPa. The compressed mass is removed from the mould, thereby obtaining electroceramic composite material. Alternatively to the use of the water soluble salt an organometallic precursor compound can be used.
