Saturation is most clearly seen in the magnetization curve (also called BH curve or hysteresis curve) of a substance, as a bending to the right of the curve (see graph at right). As the H field increases, the B field approaches a maximum value asymptotically , the saturation level for the substance.
BH) max can be graphically defined as the area of the largest rectangle that can drawn in the second quadrant of the B-H loop. The maximum energy product is defined based on the magnetic hysteresis saturation loop ( B - H curve), in the demagnetizing portion where the B and H fields are in opposition.
6 Mg(OH) 2 + 6 Cl 2 → 5 MgCl 2 + Mg(ClO 3) 2 + 6 H 2 O. Magnesium perchlorate is a white powder that is easily soluble in water, which can be obtained by the reaction of magnesium oxide and perchloric acid. The hexahydrate crystallizes from the solution, and then it is dried with phosphorus pentoxide in a vacuum at 200~250 °C to obtain the ...
With this route, stable phase 5 precipitates in a rather narrow range of conditions, namely when the concentration [Cl] of chloride anions in solution is 2.02 ± 0.03 mol/L, the concentration [Mg] of magnesium (as Mg 2+ and other cations) is 1.78 ± 0.07 mol/L, and the pH is 7.65 ± 0.05.
The typical test uses a 10 mm (0.39 in) diameter steel ball as an indenter with a 3,000 kgf (29.42 kN; 6,614 lbf) force. For softer materials, a smaller force is used; for harder materials, a tungsten carbide ball is substituted for the steel ball. The indentation is measured and hardness calculated as:
Grignard reagents or Grignard compounds are chemical compounds with the general formula R−Mg−X, where X is a halogen and R is an organic group, normally an alkyl or aryl. Two typical examples are methylmagnesium chloride Cl−Mg−CH 3 and phenylmagnesium bromide (C 6 H 5)−Mg−Br. They are a subclass of the organomagnesium compounds.
