mp-11332: UB2C (trigonal, R-3m, 166) - Materials Project

UB2C crystallizes in the trigonal R-3m space group. The structure is three-dimensional. there are two inequivalent U4+ sites. In the first U4+ site, U4+ is bonded in a 3-coordinate geometry to three equivalent C4- atoms. All U–C bond lengths are 2.44 Å. In the second U4+ site, U4+ is bonded to six equivalent C4- atoms to form distorted corner-sharing UC6 octahedra.

Boron nitride - Wikipedia

Boron nitride is a thermally and chemically resistant refractory compound of boron and nitrogen with the chemical formula BN.It exists in various crystalline forms that are isoelectronic to a similarly structured carbon lattice. The hexagonal form corresponding to graphite is the most stable and soft among BN polymorphs, and is therefore used as a lubricant and an additive to cosmetic products.

Sintering of B4C by Pressureless Liquid Phase Sintering

The effect of three different sintering additive systems on densification of boron carbide powder was investigated. The sintering additives were Al2O3:Y2O3, AlN:Y2O3 and BN:Y2O3 compositions. Powder mixtures were prepared with 10 vol% of sintering aids following conventional powder technology processes. Samples were sintered by pressureless sintering at 2050 °C/30min in argon atmosphere.
