Thermal dehydration kinetics and characterization of synthesized potassium borates

Characteristic, Electrical and Optical Properties of Potassium Borate (KB5O8·4H2O) Hydrothermally Synthesised from Different Boron Sources

“…and peak locations are matched perfectly with the reference card, the XRD score of the analysed mineral is equal to 100 [6,17].…”

“…All materials showed very close dielectric constant and AC conductivity value and characteristic results. At low frequencies (5-10 2 Hz), the dielectric constant is high about 2x10 5 to 2x10 6 and decreases to about 10 with increasing frequency for all samples.…”

“…Potassium pentaborate (KB 5 O 8 •4H 2 O) is also known as "santite" mineral. It has the orthorhombic lattice system and its crystals are at the appearance of transparent and colourless aggregates [3][4][5][6].…”

Sodyum Boratlardan Potasyum Borat Sentezi: Reaksiyon Koşullarının Optimizasyonu

“…As a different kind of potassium borate, KB3O5•3H2O was obtained from the reaction of K2B4O7•4H2O and KB5O8•4H2O in liquid state [10]. Asensio et al, studidfed thermal behaviour of santite mineral and determined the kinetic parameters of dehydration reaction [3]. As it is seen from the literature, general synthesis procedure of potassium borate is hydrothermal synthesis and it involves the steps of raw material dissolution in liquid medium, reaction at the temperatures higher than 165°C and time longer than 3 days [5][6][7][8][9][10]13].…”

“…This type of borate is also known as "santite" mineral. It has the orthorhombic lattice system and its crystals are at the appearance of transparent and colourless aggregates [1][2][3][4]. Potassium borates can be produced at dehydrated structure using the solidstate method or at hydrous structure using the liquid-state method.…”
