Morphology preservation and crystallinity improvement in the thermal conversion of the hydrothermal synthesized MgBO2(OH) nanowhiskers to Mg2B2O5 nanowhiskers

Microstructure and interface characterization of a cast Mg2B2O5 whisker reinforced AZ91D magnesium alloy composite

“…Analysis of chemical composition by EDS and SAED pattern obtained from the particles (see Fig. 4b) confirms that these particles are MgB 4 O 7 with orthorhombic crystal structure (space group Pbca) and lattice parameters of a = 1.373 nm, b = 0.797 nm, c = 0.862 nm and a = b = c = 90° [15].…”

“…Since the discovery of mineral suanite in nature [30], there has been active interest in synthesizing and characterization of the magnesium borate by means of various techniques [8][9][10][11][12][13][14][15]. Depending on the synthesis method, the Mg 2 B 2 O 5 nanowires, nanotubes and nanowhiskers can be produced.…”

“…However, there are some drawbacks for SiC whisker-reinforced magnesium matrix composite, e.g., the higher cost of SiC whiskers [3]. Recently, metal borate compounds including aluminum borate (Al 18 B 4 O 33 and Al 4 B 2 O 9 ) [4][5][6] and magnesium borates (Mg 3 B 2 O 6 [7] and Mg 2 B 2 O 5 ) nanowires/nanotubes [8][9][10][11][12][13][14][15] have been synthesized successfully. These metal borates have good mechanical properties, such as high Young's modulus and strength, good chemical inertness, and low thermal expansion coefficient [8,13].…”

Short belt-like Ca2B2O5·H2O nanostructures: Hydrothermal formation, FT-IR, thermal decomposition, and optical properties

“…The decomposition temperature was also lower than that needed for MgBO 2 (OH) [36]. Notably, ascribed to the instability and morphology ( Fig.…”

Synthesis and characterization of strontium chloroborate whiskers

“…In contrast with other synthesis approaches to 1D structures, such as solvothermal synthesis or hydrothermal synthesis, flux method synthesis needs no higher pressures or surfactants, so it is a simple and environmentally friendly process 8. However, whiskers prepared via the traditional flux technique generally have a low purity and a wide size distribution 9. Herein we report a simple route for the preparation of Sr 2 B 5 O 9 Cl whiskers using a two‐step process: the sedimentation of precursor by reaction of aqueous solution of Na 2 B 4 O 7 •10H 2 O and SrCl 2 •6H 2 O and further sintering of a mixure of SrB 6 O 10 •5H 2 O and KCl at 700 °C.…”
