Uranium dioxygen sulfate (UO2SO4) is supplied by Hubei Chu sheng wei Chemistry Co., Ltd.
It can be concluded that the C-S-H gel generated in this multiple system has dissolved a small amount of uranium containing nuclide plasma and forms a solid solution, which results in a decrease in the symmetry of the crystal structure and leads to the drift and shape change of the gel absorption band.
Besides, the stretching vibration (3 459.85 cm-1) and the bending vibration (1 636.42 cm-1) of lattice water are weaker than C3S and C2S because both the structures of their products and the water content are different.

In contrast to general cement solidification, the compositions of fly ash during a vitrification process are not physically doped one another only but chemically bonded to one part of a glass structure and are used in place of some silica sand or cement for generation of cement clinker minerals, e.g., C3S (Tricalcium Silicate), C2S (Dicalcium Silicate), C3Al (Tricalcium Aluminate), C4AF (Tetracalcium Aluminate) in which plaster is added and pulverized to be cement (C, S, A, and F denoting chemical formulas of principal compounds of raw materials such as CaO, SiO2, Al2O3 and Fe2O3).
On the other hand, the substantially reduced possibility of hazardous substances dissolved will be favorable to innocent treatment due to the hazardous heavy metals in bottom ash like lead and cadmium securely bonded to the glass structure constructed with silicon oxide mostly.

Since the structure was similar, the density of the glasses did not differ significantly.
For all the samples, most of the structure was identical, except for the minor changes made in Lanthanide content.

This theory is based on the distinct morphology of the grains of this fly ash, which, due to its disturbed structure, would be able to participate more quickly in the hydration processes.

Composition structures of NiMH battery and Li-ion battery are basically the same, i.e. cell battery pack, housing, wiring, and etc., in which cell battery mainly consists of positive electrode, negative electrode, electrolyte and housing, and etc., furthermore, Li-ion battery is configured with battery management system [17].
This article also assumes that composition of electric energy consumed during material production and battery production adopts electricity mix of China in 2012, as shown in Table 4, it can be seen that coal fired power generation predominates in electricity structure of China, hydraulic power generation is in the next place, nuclear power generation, wind power generation, natural gas power generation and other clean power generation only account for 9.2% [22].
