The electrical conductivity, σ, and thermoelectric power, S, of copper chromite (CuCr 2 O 4) are reported in the temperature range 295 to 815 K.A break (T B) in the slope of the plot of log σ against T −1 was observed around 556 K. Apart from this break, the curves are linear, and their slopes correspond to activation energies of 0.60 eV (T B <556 K) and 1.22 eV (T B >556 K).
Jun 01, 2021· Fig. 9(a) and (b) shows the variations in AC electrical conductivity (σ A C) of NiCr 2 O 4 material as a function of frequency in the temperature range 263–323 and 328–393 K, respectively. The conductivity pattern exhibited a typical behavior of ionic material, that is, it displayed a plateau-type response at low frequencies.
Mortality: No animal died prematurely. Clinical signs: other: Under the present test conditions, a 4-hour inhalation exposure to copper chromite black spinel (Pigment Black 28) at a concentration of 5.07 mg/L air revealed slight ataxia and slight dyspnoea (reduced frequency of respiration with increased volume) unti Body weight: No influence in body weight gain was noted.

Chills can be made of many materials, including iron, copper, bronze, aluminium, graphite, and silicon carbide. Other sand materials with higher densities, thermal conductivity or thermal capacity can also be used as a chill. For example, chromite sand or zircon sand can be used when molding with silica sand.
