Preparation of alumina membranes by tape casting and dip coating

Dip-coating technique for the manufacture of alumina microfilters using PVA and Na-CMC as binders: a comparative study

“…This may be achieved by addition of a surfactant and conditioning for some period of time. 9 The results of surface roughness R a measurements were rather scattered averaging about 1.85 m. However, the standard deviation followed an increasing trend with slip concentration increase and decreasing trend with the time of dip-coating (Fig. 14).…”

Preparation of carbon fibers/carbon/alumina tubular composite membranes and their applications in treating Cu-CMP wastewater by a novel electrochemical process

“…The substrates can be prepared by several methods such as extrusion, slip-casting and isostatic pressing [1,2]. On the other hand, the membrane layers can be prepared by sol-gel/slip-casting process [3][4][5][6][7], chemical vapor deposition (CVD) process [8][9][10], and others [3,11]. Of which, some investigators [8,10] have focused on developing CVD techniques using hydrocarbon precursors to coat carbon layers on the substrates and the characteristics of carbon layers such as the adsorption of dissolved organics, electrical conductivity and pore size reduction were discussed.…”

Fabrication and Crack Deflection in Ceramic Laminates with Porous Interlayers

“…This has been done by tape casting of aqueous slurries, with porosity being introduced by adding starch particles to the tapecasting slurries and then burning them out before sintering. 12,13 Starches have several advantages over other polymers. As well as being cheap and readily available, they disperse in aqueous suspensions, obviating the need for organic solvents, and decompose over a relatively wide range of temperatures, allowing a high volume fraction to be incorporated and easily removed from the green ceramic body.…”
