Sprayed powders

Other potential applications are ceramic powders coated with their sintering aids, zirconia coated withyttria stabilizer, tungsten carbide coated with cobalt, or nickel, alumina abrasive powders coated with a relatively brittle second phase such as MgAl204 and plasma spray powders without the segregation of alloying elements.

Because the handling of solids is difficult, particularly that of soft organic crystals, several crystallization processes have been developed in which solids do not appear outside the crystallizing equipment, and the product leaves the equipment in molten form. For organic substances, crystalline form and size usually are not of great importance as for products of crystallization from aqueous solutions. If needed, the molten products can be converted into flakes or sprayed powder, or in extreme cases they can be recrystallized out of a solvent. 

The preparation involves introduction of liquid and/or powdered additives into powdered basic material. Liquid additives may be introduced into separate tanks beforehand (periodically or continuously) or the material may be passed through a chamber in which the liquid is sprayed. Powdered additives may be introduced in periodic or continuous mixers. 

The fact that many products (e.g., liquids, sprays, powders, gels, some drug products, and cosmetics) cannot exist or be transported without a pack, however, means that for these types of products a broader definition is needed to cover the functions of the pack and the packaging operation.

Set-off can be avoided by the use of anti-set-off compoimds. These are spray powders that reduce the frictional contact between the sheets. Materials like silica and starch, which have a particle diameter slightly greater than the printed ink film thickness, can be used. Slow setting problems may be reduced by the use of less solvent or by a higher ratio of resin to oil. Varnishing with a formula that utilises polymerisation induced by radiation is another way to avoid set-off. The varnish covers the printed surface and direct contact between the layer of print and the iimer food contact surface of the substrate is avoided. 

In one modification of thermal spraying, powdered material is vaporized and the vapor is then condensed onto the substrate. This evaporation technique was used in early high-temperature superconductor research to deposit c-axis preferred orientation YBa CUjO at deposition rates of up to 10 microns/inin. °... 

A number of processes were developed that use CVD, PVD, plasma spray, powder metallurgy, SHS, and galvanoforming. Several combined processes were also developed including CVD/CVI, PM/CVD, SHS/HIP, and plasma spray/galvanoforming. Various FGM samples were fabricated such as disks of SiC/C, AlN/SiC, PSZ/stainless steel, PSZ/Ni, TiC/Ni, Cr3C2/Ni, TiB2/Cu nose cones of SiC/CC and rods of PSZ/Ni. 

TiC/Mo FGM coatings were sprayed onto Mo substrate by the plasma twin torch spraying system shown in Figure 1. In this system, each plasma torch to spray powder particles of Mo metal or TiC ceramics was operated at the same time under spraying conditions shown in Table 1,... 

The substrate material was TC4(Ti-6Al-4V), and the sprayed powders were 8wt%Y203 partially stabilized Zr02 and Ni-4.5Co-20Cr-4Al-lY alloy, the Zr02/NiCoCrAlY graded coating was fabricated by air plasma spraying process . ... 

Fig.2a and Fig.2b is the surface morphology of Zr02 and NiCoCrAlY component respectively. It could be found that the sprayed powders deformed severely. In spraying process, the melted powders impact on the surface of substrate or deposited layer at very high speed, and lead to the particles flow and deform along the surface. It could be also found that some pores and undeformed spherical particles with very small size remain at the interface between deformed particles. 

At the short end of the scale (of the order of 10 cm) the motion may be due to convective instability in a shallow surface layer as explained by Gem-merich and Hasse (1992). They made field observations of the surface motion by spraying powdered corkwood on the surface, watching how it collected on a time scale of 10 seconds or less, into various structures depending on the condition. Lines were by far the most common structure observed. They may, for example, be caused by convective rolls along the wind drift direction. 

Econazole. Econazole and isoconazole are structurally very similar to miconazole they differ only in the pattern of chlorine substitution on the terminal phenyl ring. Chemically, econazole (Fig. 2, 7b) is closely related to miconazole. The clinical indications are almost identical. Econazole [27220-47-9] is available as a vaginal cream and ovule containing respectively 1% and 150 mg econazole nitrate. For mycoses of the skin, several forms are available including cream, spray-powder, spray-solution, and lotion. All these formulations contain 1% econazole nitrate [68797-31-9]. The dosages are practically identical to those of miconazole.

EXPLOSION and FIRE CONCERNS combustible solid liquid formulations containing organic solvents may be flammable risk of fire and explosion if formulations contain flammable or explosive solvents incompatible with alkaline materials and strong oxidizers on combustion, forms toxic and corrosive fumes of hydrogen ehloride use water spray, powder, alcohol foam, or carbon dioxide for firefighting purposes.
