May 01, 2013 May 01, 2013 A carbon–silicon carbide (C p –SiC) composite powder was prepared with nano-carbon (C p) and silicon (Si) powders as starting materials via a mechanochemical treatment in Ar atmosphere in a stirred ball mill. The composite powder was characterized by X-ray diffraction (XRD), thermogravimetry/differential scanning calorimetry (TG/DSC), scanning electron microscopy (SEM)
For the sintering process 2 g of wollastonite in 5 mL of ethanol were ground for 30 minutes in a tungsten carbide ball mill Fritsch Pulverisette 6 planetary mill (Idar-Oberstein, Germany), at a

An example of the latter is the synthesis from a slurry ... low temperature microwave synthesis of novel carbon nanotube–silicon carbide composite
Read MoreTiN/Si 3 N 4 composite powders were obtained by a process that combines the mechanical activation of titanium and silicon powders at room temperature through high-energy milling with an isothermal annealing in a nitrogen atmosphere to complete the synthetic reaction. Mechanical activation has allowed us to complete the synthesis at 1350 C only
Read MoreJun 03, 2019 Jun 03, 2019 A mixture of SiO2, C, and Mg powders is mechanically milled in a planetary ball mill during different milling times of 60, 90, 120, and 150 min. The milled powders are then used in a self-propagating high-temperature synthesis (SHS) reaction to produce the Si–SiC composite. The thermal properties of the milled powders are determined by using differential
