Changes in inorganic constituents of coal in combustion process of pulverized coal can be divided into four categories, i.e., in the effect of temperature: the native minerals are broken down into simple compounds; combustible components of the coal (sublimate and overflow) are brought out and form aerosols; form new substances in the combustion zone; fusion and melting of non-combustible materials [4].In the combustion process, characteristics of the minerals in coal varying with temperature [5] Pyrite or marcasite pyrrhotite + sulfur Pyrrhotite + sulfur + oxygen hematite + magnetite + sulfur dioxide Hematite + magnetite part is converted to the glass phase amorphous iron oxide Calcite lime (CaO) + carbon dioxide Lime (CaO)) + sulfur dioxide + oxygen anhydrite Clay mineral dehydration and dehydroxylation Glass Glass + mullite + cristobalite Glass + mullite + cristobalite + Na2O + K2O Quartz part melting and glass formed Ashing Behavior of Minerals

Pseudopartial Grain Boundary Wetting: Key to the Thin Intergranular Layers B.B.
Introduction The unique properties of the nanostructured materials are of great importance for various advanced applications.
For the microstructure of liquid-phase sintered materials, a quantity known as the contiguity parameter has been defined [37, 38].
It is an important example, how the GB engineering (tailoring the polycrystal properties by controlling the GB structure and composition) can improve the properties of nanostructured oxides for fuel cells.
As many high-temperature materials, it is produced with the aid of liquid-phase sintering.

Cleavage cracks form in the work-hardening region of materials response, whereas twining is restricted to the Lüders region [31].

Size Effects in Electroformed Nanomaterials Uwe Erb University of Toronto Dept. of Materials Science and Engineering Toronto, Ontario, M5S 3E4, Canada erb@ecf.utoronto.ca Key Words: Electrodeposition; fully dense nanomaterials; grain size-dependent properties; grain size-independent properties; intercrystalline volume fractions; grain boundaries; triple junctions Abstract This paper reviews size effects in nanocrystalline metals and alloys made by electroforming, a particular form of electrodeposition.
However, this number can be substantially increased to over 80% in what is referred to as grain boundary engineering.
The ultimate goal of grain boundary engineering is to increase the overall properties of polycrystalline materials by creating high frequencies of special grain boundaries with better properties.
It should be noted, however, that these materials were two phase materials consisting of fcc Ni and a bct Ni3P phase.
