To produce useful information about the raw materials used in northern Chinese Yaozhou celadon glazes (especially source of calcium‐bearing flux), Sr isotope analysis has been for first time. is one most important representatives greenware. The study enhanced our understanding material sources to make dating from Tang Northern Song dynasties. It highly likely that ‘Fuping stone’ mentioned historical record not main results 87 Sr/ 86 studied relatively consistent isotopic signatures, with a...
A Ti3AlC2/Al2O3 nanocomposite was synthesized using Ti, Al, C and TiO2 as raw materials by a novel combination of high-energy milling hot pressing. The reaction path the 3Ti-8C-16Al-9TiO2 mixture powders investigated, results show that transitional phases TiC, TixAly Al2O3 are formed in first, then is transformed to TiAl phase during Finally, between TiC occurs produce Ti3AlC2 nanosized composite synthesized. possessed good mechanical properties with hardness 6.0 GPa, flexural strength 600...
BaFe12O19/Ba0.6Sr0.4TiO3 (BaM/BST) composites were synthesized via the conventional solid-state reaction method. The phase composition and surface morphology of investigated by using X-ray diffraction (XRD) scanning electron microscope (SEM), respectively. electrical magnetic properties also studied. results show that BaM/BST have giant dielectric constants very high remnant magnetizations. behavior is mainly attributed to Maxwell–Wagner polarization.
AbstractAbstractTwo kinds of glass (LiBZn and BaBSi) were used as sintering flux to lower the temperature Y3Fe5O12 (YIG). The X-ray powder diffraction patterns confirm coexistence two phases. dielectric magnetic properties also reported. results show that addition LiBZn is 8 wt-%, YIG can be sintered at 1100°C, which than (1350°C) pure YIG. with wt-%LiBZn glass, possessing high equal permittivity, permeability, cut-off frequency very low loss, fabricate miniature filter antenna,...
Al2O3/TiAl composites were successfully fabricated from powder mixtures of Ti, Al, TiO2, Cr2O3 and Nb2O5 by a hot-press-assisted exothermic dispersion method. The effect the addition on microstructures mechanical properties was characterized. results showed that specimens are mainly composed TiAl, Ti3Al, Al2O3, NbAl3 Cr2Al. Vicker-hardness density increase gradually with content. When content 6.54 wt %, flexural strength fracture toughness have maximum values 789.79 MPa 9.69 MPa?m1/2,...
In this article, the Frenkel?s theory of liquid-phase sintering was interpreted regarding pores as activated volume. The mathematical model established by Nikolic et al. used to infer equilibrium time at varied temperatures during isothermal codierite glass Giess Through calculation, 800?C, 820?C, 840?C and 860?C is inferred be 7014.42mins, 1569.65mins, 368.92mins 114.61mins, respectively. decreases temperature increases. And theoretical value in good accordance with experimental results....
Abstract High voltage zinc varistors were synthesized by high-energy milling with Pr6O11 and Y2O3 doped ZnO-Bi2O3 system as raw materials. The effects of on the microstructures, electrical properties densities samples investigated in detail. results show that make as-prepared have refined homogeneous which result improving their properties. optimal prepared obtained for 7.5 hours sintering at 1100°C, exhibited varistor (V1mA ) about 533 V/mm, non linear coefficient (α) reaching 36 leakage...
AbstractPowders of (Bi3/2Zn1/2)(Zn1/2Nb3/2)O7 (BZN) were prepared by the polymerised complex method, based on Pechini type reaction route. The crystallisation process BZN during calcination an amorphous precursor was observed, using thermogravimetric and differential scanning calorimetric analysis X-ray powder diffraction. After powders ball milled, pressed into pellets sintered at 950°C, which is lower than temperature conventional solid state method. Using this procedure we achieved...
