temperature synthesis methods include ball-milling and chemical vapor deposition (CVD). In ball-milling, finely-milled precursor powders of B and catalyst are annealed in an N2 or ammonia gas atmosphere, sprouting nanostructures on their surfaces [10-13]. In CVD, a B-containing vapor, for example B2O2, reacts with a nitrogen-containing gas,
Due to the volatility of P2S5, the ambient pressure synthesis of Li2S + P2S5 (LPS) has been limited to planetary ball-milling (PBM). As a result, LPS doped with SiS2 has been studied because SiS2 lowers the vapor pressure of the melt and promotes strong glass formation which combined allows for greater ease in synthesis. In this work, we have examined the struc-tures and electrochemical ...

involves a vapor-mediated recrystallization, while the reverse phase transition upon heating is a nucleation-and-growth solid− solid phase transition. The lifetime-extending effect of DMU on spray-dried PZA has been investigated in more detail and compared with high-energy ball milling of sublimation-grown γ-PZA crystals.

Ball milling was carried out using a Spex 8000 mixer mill as follows: first, 0.81–0.84 g of fibers were weighed and compressed, if necessary, into a 100-ml beaker. Then two 1⁄8 in. and one 1⁄2 in. steel balls (or ten 1⁄8 in. plastic balls) were placed in the ball-mill vessel's smaller sec-tion (about 38-mm inside diameter), with ...
methods are ball-milling and chemical vapor deposition (CVD). Both of these techniques require catalysts but are capable of producing hundreds of milligrams to grams of BNNTs. Typically, BNNTs produced by CVD and ball-milling are multi-walled and possess large diameters (~ 50 nm). In addition, these tubes frequently suffer from faceted/wavy
