Stabilization of Cr(III) wastes by C3S and C3S hydrated matrix : comparison of two incorporation methods [PDF]
, 2015 In the present study, the influence of Cr(III) on the properties of C3S and its stabilization in C3S hydrates was investigated by either direct incorporation as Cr2O3 during C3S preparation or introduced as nitrate salt during hydration.

Creep of Reaction Sintered and Liquid Phase Sintered Sialon
Journal of the Mechanical Behavior of Materials, 1990 Creep experiments were conducted with 100—250 MPa stress at 1200-1450°C of Reaction Sintered (RS) Sialon A synthesized from Si3N4-AlN-Al203 and Liquid Phase Sintered (LPS) Sialon C, CI synthesized from Y203-A1N-Si02 systems. RS Sialon A, containing no liquid phase sintering aid, had better creep resistance than LPS Sialon C, CI.

Effect of carbon nanotube doping on critical current density of MgB2 superconductor [PDF]
, 2003 The effect of doping MgB2 with carbon nanotubes on transition temperature, lattice parameters, critical current density and flux pinning was studied for MgB2-xCx with x = 0, 0.05, 0.1, 0.2 and 0.3. The carbon substitution for B was found to enhance Jc in
