The X-ray diffraction analysis of carbon micro-crystal structure of the foundry formed coke prepared by semi-coke

The product is formed as hollow beads and has a microcrystalline structure with an extensive inner surface and a wide porous system.

The results show that nuclei make the microcrystalline structure and crystalline rate of PA1010 changed.

The resul ts show that the activated carbons obtained by the combined method have higher s pecific surface area than that prepared by the normal physical activation, and t he KOH has obvious effects on the microstructure and the morphology of the GACs.

The crystallite structure parameters of obtained cokes were calculated by XRD.

The appearance,particle size distribution and crystallite structure of the MCMB were investigated by SEM,laser particle size analyzer and XRD.

This paper introduced the relationship of microcrystal structure of coke and its macroscopical properties,and the effects of coal rank and pyrogenation process on microcrystal structure etc.

The formation mechanism of phase interface-layer with microcrystal structure in Ti(C, N)-based cermet has been discussed.

The microcrystal structure of coal was studied by use of x-ray diffraction- The results have shown that the microcrystal parameters d002,Lc and La of coal change by stages in coalification process,which leads to a similar change in physical and chemical properties of coal,and the sudden change zone is of ten in the range of 88%~90% carbon content.
