“…15 At 1300 • C, more rapid grain growth results in preservation of pore space, which impedes efficient reduction of porosity. Average H 2 O contents for the bulk specimen (both structurally bound water and water adsorbed on the grain boundaries) of the hot-isostatically pressed and mechanically tested samples (sections 285 m thick) were determined by Fourier transform infrared spectroscopy (FTIR).…”

The first high-temperature mechanical spectroscopy experiments on high-purity polycrystalline MgO reveal a monotonically frequency-and temperature-dependent dissipation 'background'-without any evidence of the superimposed dissipation peak observed in a previous study of a specimen of lower-purity [Webb, S. and Jackson, I. Phys. Chem. Min., 2003 30, 157]. The dissipation and associated relaxation of the shear modulus observed in both studies are well described in an internally consistent manner by a novel Burgers-type model based on a creep function incorporating suitable distributions of anelastic relaxation times. The contrasting patterns for the two materials reinforce an emerging generalisation concerning high-temperature viscoelastic behaviour, whereby the presence of a secondary intergranular phase of relatively low viscosity, and the associated rounding of grain edges, is apparently required to allow elastically accommodated grain-boundary sliding. The absence, in sufficiently pure polycrystalline materials, of a dissipation peak attributable to elastically accommodated grain-boundary sliding is in conflict with classical micromechanical models for grain-boundary sliding, which are therefore being revisited.

“…Densification of ultrafine and nc-MgO by hot pressing was thoroughly investigated. 54,[63][64][65][66][67] Pressure calcination of Mg(OH) 2 powders at 1000uC and 46 MPa resulted in fully dense MgO specimens albeit with micrometre grains. 54 The effect of the particle size in the range of 10 to 260 nm on the densification and grain growth behaviour was investigated using nc-MgO formed by vapour phase oxidation.…”

“…As for SG, it is advantageous in the synthesis of nano-sized materials due to the fact that it has the advantages of simple procedure, low crystallization temperature, and low cost. This technique involves a colloidal solution which transforms into gel, producing high purity and chemically homogeneous materials [2,13,14].…”
