Effect of B2O3 on the Structure and Viscous Behavior of Ti-Bearing Blast Furnace Slags

Influence of Al2O3, CaO/SiO2, and B2O3 on Viscous Behavior of High Alumina and Medium Titania Blast Furnace Slag

“…The viscosity of CaO-13% Al 2 O 3 -SiO 2 -MgO-18% TiO 2 -B 2 O 3 slags decreases with increasing B 2 O 3 addition in our previous investigation [14]. Similar results are obtained by Sun et al [11], Fox et al [26], and Wang et al [27] despite different compositions. Besides, the break point temperature of slag was decreased by the addition of B 2 O 3 , as shown in Figure 6.…”

“…It has been found that the little amount of B 2 O 3 remarkably improved the properties of slag [11][12][13][14][15]. Influence of B 2 O 3 on high titanium (above 20%) BF slag [11][12][13]16], medium titanium (10%-20%) BF slag [14], and high alumina (above 15%) BF slag [17,18] has been studied in previous reports. However, it is hard to find investigations on the viscous behavior of high alumina (above 15%) and medium titania (15%-20%) BF slag (HAMT BF slag) and the influence of B 2 O 3 , Al 2 O 3, and basicity on viscous behavior.…”

Short-range and Medium-range Structural Order in CaO–SiO₂–TiO₂–B₂O₃ Glasses

“…Considering the varying content of BO-NBO in the glasses, the equilibrium reaction could be described as follows: 11,12) BO +NBO BO As aforementioned, the clarification of the structural units of the glasses itself was extremely interesting and this could also enable an exploration of the structure-property relations. First, for the viscosity change, [17][18][19][20] the dominant existence of the two-dimension BO 3 trigonal in the threedimension networks could weaken the whole rigidity of the structures. This effect could thus cause a decrease of the melt viscosities, despite the increasing DOP of the glasses.…”

“…Studies on viscous flow behaviors of the borosilicate melts [17][18][19][20] generally show a decreasing viscosity with increasing B 2 O 3 content in the melts. In addi-tion, in a previous study on crystallization behaviors, 21) we found that a B 2 O 3 addition of 5% brought about a drastic change of primary crystalline phase in a CaO-SiO 2 -MgOAl 2 O 3 -TiO 2 -B 2 O 3 melt, viz., from CaTiO 3 to TiO 2 .…”

Structural Roles of Boron and Silicon in the CaO-SiO2-B2O3 Glasses Using FTIR, Raman, and NMR Spectroscopy

“…[1][2][3][4] and metallurgical industry. [5][6][7][8][9] The macroscopic properties of these glasses and melts are primarily determined by the microscopic structure; thus it is of crucial importance to acquire the structural environments of boron (B) and silicon (Si) including the role and coordination conditions. Meanwhile, numerous studies [5][6][7][10][11][12][13][14][15][16][17] explored the viscous flow behavior and analyzed the variation trend of the viscosities of B 2 O 3 -bearing melts.…”
