pH in chemistry refers to a logarithmic scale used to specify the acidity or basicity of an aqueous solution.
In Figure 5, the data of B = 0.64 (B was defined as the optical basicity value of the composition excluding [Fe.sub.x]O) was cited from our previous research [23].
However, it is hard to find investigations on the viscous behavior of high alumina (above 15%) and medium titania (15%-20%) BF slag (HAMT BF slag) and the influence of [B.sub.2][O.sub.3], [Al.sub.2][O.sub.3], and basicity on viscous behavior.
The starting amino-compound and the resulting compounds were analyzed by the conventional method of potentiometric titration of a mixture of primary, secondary, and tertiary amines with the definition of the total basicity [B.sub.T], the basicity of secondary and tertiary amines [B.sub.2,3], and the basicity of tertiary amines [B.sub.3].
This high basicity, neutral, agglomerated flux has been upgraded and now is especially suited for narrow gap welding because of its good slag detachability, concave weld bead profile and smooth sidewall blending.
The basis properties (completeness, minimality, and Schauder basicity) of systems of the form ([omega](t) [[phi].sub.n](t)}, where ([[phi].sub.n](t)} is an exponential or trigonometric (cosine or sine) system, are investigated in several papers (see, e.g., [1-15]).
Oceans cover 70 percent of our planet, and seawater is actually basic, not acidic, but as an estimated 30-40 percent of carbon dioxide released into the atmosphere due to human activity is dissolved in the oceans, the basicity of seawater reduces and moves toward being pH-neutral, like pure water.
Slag analysis is put into terms of basicity. A typical target basicity for North American cupola operations is 0.5-0.6, although some very good operations may be as low as 0.3 or as high as 0.8.
Moreover, CO2-TPD results revealed that the incorporation of Ho in Ni/ZrO2 catalyst fairly enhanced its Lewis basicity.
6] that for state of tetrafluoroborate ion in coordination bonds in case of two-charging metals the electron-donor ability (basicity) of Am has the paramount importance.
