“…However, in all cases we deal with predominantly flaky morphology of particles which have friable enough surface layer the structure of which we may interpret as a polymeric element organic formation with high disperse (∼10 nm) iron containing additions. Such surface formations could relate to "claspols" [7]. This fact supports a conclusion we made above while researching magnetic properties of quartz powder with surface modified by mechanochemical processing [5].…”

There were taken and analyzed electron-microscopic images of quartz particles after mechanochemical processing in mill-activator with different organic modifiers. It was stated that quartz surface suffers serious changes the peculiarities of which are defined by used modifiers. Quartz particle has a complex flaky morphology.<br />Friable surface layers represent as carbonic element-organic formations with ferrous additives. The change of particle's surface layers are responsible to modified quartz physicochemical properties transfer.

“…To reduce the powder agglomeration, an alternative method to produce a precursor containing uniformly distributed metallic particles is through in situ thermal decomposition of organometallic compounds 11–15 . For example, Gubin and colleagues have prepared a series of functional ceramics containing nanosized metal particles 16–18 .…”

Silicon carbide (SiC) fibers are prepared using an iron-containing polycarbosilane (Fe-PCS) as the precursor. Iron pentacarbonyl [Fe(CO) 5 ] is first reacted with low-molecular-weight liquid PCS to form an iron-containing colloid. The colloid is then added into high-molecular-weight solid PCS to form Fe-PCS. Formation of the iron-containing colloid as well as the SiC fiber processing has been studied. It is found that during the preparation of the colloid, the iron pentacarbonyl first decomposes under heat into nanosized carbonyl derivatives and CO. CO then reacts with liquid PCS at the interface, rendering liquid PCS cross-linked and hence the particles encapsulated. At a higher temperature, the derivatives further decompose into nanosized iron particles. The iron exists as nanosized a-Fe domains (B5 nm) and is highly uniformly distributed inside the ceramic fibers. Ceramic fibers containing 3.64 wt% iron have a good combination of tensile strength (2.37 GPa), electrical resistivity (0.46 X . m) and magnetic properties (a saturation magnetization of 1.48 A . m 2 /kg and a coercivity of 5094 A/m).
