of recent research work for rapid and controlled synthesis of homogeneous nano-sized powders which have low sintering temperature, high density and improved microstructure for the fabrication of ceramics [ 19 ]. In sol spray process, the sol solutions

-temperature sintering but the product is coarsed, whilst application of sol–gel auto-combustion method allows to produce nanocrystalline ferrite in low temperature (ca 400 °C). Unfortunately, this method could not be used to synthesize ferrite powder from sulphate

coke removal by oxidation of atomic carbon formed on surface. However, the oxygenated additives may accelerate the sintering phenomenon or increase the selectivity to carbon oxides [ 12 ]. Very few investigations, however, have reported the effect of

stages in the fabrication of ceramics are shaping of powders and sintering. There are many shaping techniques in ceramic technology but most of them have important disadvantages such as nonhomogeneity of powder compacts, size and geometry limit of

sintering and ceramic bonding [ 2 ]. This article is concerned with investigation of dehydration reactions which occur from the moment when water is added (at the beginning of components mixing), to the moment when installed refractory concrete

Abstract  

The 12C(d,n)13N reaction, at 2 MeV, was used for the stoichiometric determination of carbon in reference materials and sintered pellets of SiC ceramics. The preliminary results show higher percentage of carbon on the surface in comparison to the core of the sintered ceramics, indicating the existence of carbon contamination on the surface, possibly caused by the sintering process itself.
