The growth mechanism of the basic magnesium chloride whisker

Abstract

Based on the theoretical model of anion coordination polyhedron growth units, the growth mechanism of the basic magnesium chloride whisker was discussed in this paper． It was found that the basic magnesium chloride whisker habits were related to the different environments in which anion coordination polyhedra grew. The growth units of basic magnesium chloride whiskers are 2 4 [Mg (OH) ]   and 2 4 [Mg Cl ] .  The growth process is the incorporation process of growth units. Growth units will have different incorporations and orientations caused by different system characters or heating. Furthermore, the formation mechanism of basic magnesium chloride whiskers was also interpreted using anion coordination polyhedron growth units.anion coordination polyhedra, basic magnesium chloride, whisker, growth mechanism, crystal morphology Citation: Wu J S, Xiao Y K, Su J Y, et al.

Synthesis of Basic Magnesium Chloride Whisker in MgO-HCl-H2O System at Room Temperature

“…6 shows the SEM images of the samples, the results show that the whisker shape maintained still very well in the Mg(OH)2. The fact of the basic magnesium chloride wkiskers can be transformed into Mg(OH)2 whiskers by base NaOH treatment provided an evidence of that the Cl anions were rather than the structure of the free in the basic magnesium chloride wkiskers 2,5,8 .…”

“…They have similar molecular structure and same function characteristics of the enhancement, flame retardant and filler application in engineering plastic 1 . The basic magnesium chloride whiskers with a general formula of xMg(OH) 2 •yMgCl 2 •zH 2 O (x = 2,3,5,9; y = 1; z = 1,2,3…..) 2,3 were discovered and applied in cement 4 . The basic magnesium chloride whiskers could generally be synthesized in a typical method by using magnesium oxide powder and magnesium chloride solution as raw materials [5][6][7][8] .…”

It could also be synthesized by using magnesium chloride solution and NH 3 •H 2 O, Ca(OH) 2 , NaOH, CaO, as raw materials 2,9,10 . the phase form 318 with the formula 3Mg(OH) 2 •MgCl 2 •8H 2 O were one of the most important and fundamental phase form on which being extensive investigated 11 .…”

Growth habit of the basic oxysulfate magnesium whisker

“…Due to the fact that the improved hydrothermal method has great advantages [7][8][9] , the synthesis and characterization of basic oxysulfate magnesium whiskers were done according to a previous paper [10] . Using the hydrothermal method, a solution with 25% volume fractions of butanol was prepared, and then solutions of 0.1 mol·L −1 MgSO 4 ·7H 2 O and 0.1 mol·L −1 of NaOH were prepared by using the butanol solution as diluent.…”

Quasi-exact thermodynamic properties of a relativistic spin-zero system under Cornell and generalized Morse potentials

“…Magnesium hydroxide has potential applications in various fields, due to the fact that it is capable of greatly increasing the strength, rigidity, dimensional stability, and deformation temperature of plastic. 1,2 Previous studies have reported on the development and application of magnesium hydroxide whiskers. However, recent research concerning magnesium hydroxide whiskers has not provided reasonable explanations for the following problems: first, what is the unit cell structure of magnesium hydroxide whiskers?…”
