Solidification mechanism and microstructure evolution of Al 2 O 3 -ZrO 2 ceramic coating prepared by combustion synthesis and thermal explosion spraying

Mechanism of formation governs the mechanism of release of antibiotics from calcium phosphate nanopowders and cements in a drug-dependent manner

“…26 Thanks to this combination of high nucleation rate and low crystal growth rate, ACP can be produced by simple precipitation reactions at room temperature, without having to rely on melt atomization or quenching at extremely high cooling rates, as most other ceramic materials do. [27][28][29] The slow crystal growth is also responsible for the wide variety of HAp crystal growth habits and particle morphologies producible by natural 30 or synthetic 31 means.…”

Microstructural evolution of supra‐nanostructure Al2O3/ZrO2 eutectic powders by combustion synthesis‐spray cooling

“…Furthermore, the cooling rate obtained in this work is of the same order of magnitude as the cooling rate to form eutectic structures of Al 2 O 3 -ZrO 2 . 35,36 Combining the simulation results and the cross-sectional microstructure (Figure 4), it can be concluded that the microstructure of Al 2 O 3 -ZrO 2 eutectic powders of different size are different due to the changes of the cooling rate. Moreover, the temperature platforms of ~2143 K are found in the curves ( Figure 5A), which associate with the melting point of Al 2 O 3 /ZrO 2 eutectic.…”

Study on a New Cleaner Emulsion Explosive Containing Common Clay

“…Results presented above show that the decreasing tendencies of detonation velocity and explosive brisance realized by increasing the amount of common clay or HGMs make this kind of new emulsion explosive more suitable when used in some specific industries, requiring rather poor detonation properties, such as explosive spraying or the formation of metal parts [19][20][21].…”

“…Further, the usage of sifted gravels can increase the overall cost of modified emulsion explosives, which would limit the popularization of this product. Therefore, to overcome those disadvantages of current emulsion-explosive products, broaden their applications, i. e., using in the field of explosion spraying, which also requires a low detonation velocity of less than 3500 m s À1 [19][20][21], and minimize environmental pollution during usage, a new and much cleaner emulsion explosive which adds common clay (never been used before in the civil explosive field) as the inert additive is developed, rather than using above-mentioned traditional defective additives.…”
