Song, Microstructure and phase evolution of TiO2 precursors prepared by peptization-hydrolysis method using polycarboxylic acid as peptizing agent, Mater.
Key statement: A first tire member manufacturing method includes an operation in which a masterbatch is made, and an operation in which the masterbatch, peptizing agent and processing additive are mixed.
Effective regulators of viscosity and the ultimate shear stress of asphaltene-containing ODS are surfactants that exert peptizing action, blocking the adhesion planes of particles and decreasing the strength of contact between the layers of the dispersion medium through which the particles of the disperse phase contact [33].
The appropriate amount of the butoxide was mixed with deionized water and nitric acid in a molar ratio of 1:100:0.07, covered with aluminum foil, and stirred overnight on a hot plate to complete the peptizing. For most of the catalysts, a measured amount of Pd ammine nitrate was added directly to the wet sol; this method of precious metal addition is often referred to as a "catalyzed slurry" or "one-pot" technique.
As the SOR increases, more resins are solubilized by the solvent and these are unable to act as peptizing (or interfacial) agents of asphaltenes [116-119] leading to their aggregation and precipitation [81,116-119].
(147) On the contrary, even a combined application of peptizing surfactants and ultrasonic agitation after the precursor particles yields only particles in the ranee of 100-250 nm.

The <1 [micro]m fractions from soil horizons were separated by sedimentation and decantation, followed by dispersion by addition of a few drops of ammonia as a peptizing agent.
Model samples were prepared with the latex of one clone, by blending the latex of two clones, or by peptization with Struktol LP 150 (Shill & Seilacher, Germany) as the peptizing agent (150 g/t NR).
