I’ve lodged a dispute with PayPal, but if they already have a problem with this supplier they should not be taking our money!

The morphological and structural properties of the Fe3O4 nanopowder are characterized by transmission electron microscopy , nitrogen adsorption–desorption, and thermogravimetric analysis . Monodisperse, nearly spherical and highly crystalline Fe3O4 nanoparticles are obtained by this method. The Fe3O4 nanopowder is well dispersed in water and ethanol with a mesoporous structure, average pore size of 3.6nm, and Brunauner–Emmett–Teller surface area of 122m2/g.

I ordered from a company called Rappust which doesn’t exist anymore.

Studies were carried out to uniformly coat SiC over the graphite substrate, using halide activated pack cementation method. Experimental results revealed that the optimum pack composition for adherent and dense coating was 2.5wt.%NH4F–15wt.%Si–82.5wt.%Al2O3. Uniform, homogeneous and dense SiC coating with an average coating thickness of 5μm was obtained at the deposition temperature of 1400°C.
