A vibrational spectroscopic study of the borate mineral takedaite Ca3(BO3)2

Structure and Properties of the Non‐Centrosymmetric Manganese(II) Borate Mn5(BO3)3OH

“…Figure shows the single‐crystal FT‐IR spectrum of Mn 5 (BO 3 ) 3 OH in the range from 600 to 4000 cm –1 . The assignment of the modes is based on previous works, investigating borates containing trigonal planar BO 3 groups . In the fingerprint region, the deformation and out‐of‐plane bending vibrations from the trigonal planar BO 3 groups can be found ranging from 600 to 800 cm –1 .…”

Thermochemical processing of boron-impregnated cellulose insulation waste for upcycling to slow-release boron fertilizers

“…1, Fig. 2) (Frost et al, 2014), which likely was the result of the thermal decomposition of CaCO3 to CaO and the subsequent reaction between CaO and B2O3. With the combustion of CFI at 800 °C, the takedaite phase was less pronounced and crystalline B was also found in shimazakiite (Ca2B2O5, BO3 coordination) and fabianite (CaB3O5(OH), BO4 coordination) phases, with both NMR and FTIR (e.g.…”

Influence of the slight adjustment of oxides on the structural and physico-chemical properties of thin film transistor-liquid crystal display substrate glass

“…The third highest peak intensity was in the middle frequency at around 803 cm −1 relating to the symmetric stretching vibration of Si-O b -Si between [SiO 4 ] tetrahedrons [9,12]. Some weaker intensity peaks distributed at around 710 cm −1 , 1310 cm −1 and 1440 cm −1 could attribute to the vibration of the B-O bond, wherein a peak at 710 cm −1 is assigned to B-O-B bending vibration in the [BO 3 ] triangle [13], and peaks located at around 1310 cm −1 and around 1440 cm −1 are assigned to B-O b stretching vibration and B-O nb stretching vibration in the [BO 3 ] triangle, respectively [14].…”
