WitrynaFigure 10.37 The entities of a solid phase may be arranged in a regular, repeating pattern (crystalline solids) or randomly (amorphous). Metals and ionic compounds typically form ordered, crystalline solids. Substances that consist of large molecules, or a mixture of molecules whose movements are more restricted, often form amorphous … WitrynaEdit. View history. Basic sediment and water (BS&W) is a both a technical specification of certain impurities in crude oil and the method for measuring it. When extracted from an oil reservoir, the crude oil will contain some amount of water and suspended solids from the reservoir formation. The particulate matter is known as sediment or mud.

Witrynatheory of solids with impurity atoms, which is now called the method of local perturbations. This method is an integral part of a new direction in solid state theory—the theory of disordered systems, created mainly by I. M. Lifshits and his collaborators. This method was used to calculate the characteristics of local and quasi- WitrynaThe authors hypothesized that such impurity elements can attract electrons in the diffusion path more strongly to further reduce charge density. In addition, the solid solubility limit of Ta 5+ is similar to that of Nb 5+ because the ionic radius of Ta 5+ (64 pm) is the same as that of Nb 5+.
