Thermal shock of ceramic material : Damage resistance parameters and critical flaw size
(Trans Tech Publications Ltd., 1997)
The alumina refractories used in this study included a serias of 12 commertial products (two fireclay and ten high alumina brands ) containing ≈ 45 - 90 % Al2O3. Damage resistance parameters R,, R, and RSt were used in ...
Size distribution of ultrafine spherical ceramic powders obtained by ultrasonic spray pyrolysis
(Trans Tech Publications Ltd., 1997)
Comparative analysis of experimentally determined particle size distribution and theoretically calculated aerosole drop size distribution (obtained on the basis of 3D model of spherical / elliptical waves generated by the ...
Graphic simulation of STM images of Si(111)7X7 surface
(Trans Tech Publications Ltd., 1997)
The posibilities of graphic STM image simulation at atomic level are indicated. The presented procedure takes into account various types of deformation on the surface near the Fermi level. A clean Si(111)7X7 surface is ...
Synthesis of spinel powders by the spray pyrolysis method
(Trans Tech Publications Ltd, Durnten-Zurich, 1997)
In this paper synthesis of spinel powders by the two-fluid spray pyrolysis method was performed. The influence of the precursors (AlCl3·9H2O and MgCl2·6H2O for S-1 powder and boehmite sol and MgCl2·6H2O for S-2 powder) on ...
Thermal shock of ceramic material : Comparison of resistance parameter with the critical ΔT values ΔTc = ΔTc(Bi) of ceramic materials
(Trans Tech Publications Ltd., 1997)
Thermal shock resistance of ceramic material can be characterized by using resistance parameters or critical temperature difference. Correlation between fracture resistance parameter, R and critical temperature difference, ...
