Determination of the high temperature zeta potential and pH of zero charge of some transition metal oxides

The effect of temperature on the yield stress of mineral suspensions

“…Such a change in the IEP has been observed in other metal oxide systems [17][18][19] and can be related to the change in the neutral point, 1 2 pK w of water as the temperature is increased. In their work on alumina, Tewari and McLean [19] confirmed that the value of the observed alumina IEP-1 2 pK w was almost constant indicating that the change in IEP with temperature is associated primarily with the water ionisation constant changes.…”

Surface force arising from adsorbed graphene oxide in alumina suspensions with different shape and size

“…If the model is obeyed, then the yield stress should decrease linearly with the square of the zeta potential where for many suspensions this has been the case. [39][40][41] Generally, the yield stress of most suspensions does not scale to / 2 . In the presence of adsorbed additive, the minimum separation distance between two interacting particles in the flocculated state will be increased by the adsorbed layer.…”

High‐Temperature Electrochemistry: A Review

“…A survey of the literature reveals that other applications of autoclave heating include: the development of ceramic membranes for high-temperature pH measurements [7], electrochemical measurements in liquid and super-critical CO 2 [77], the invention of an autoclave system that incorporates a scanning-tunneling microscope for use in hightemperature electrochemical STM experiments [11] and studying the electrochemistry of various molten salts [18,78,79]. The details of novel reference electrode designs [5,6,8,14,15,20,21,23,80] and the measurement of analytical data [80] will be discussed later in Sections 3 and 4 respectively.…”
