Abstract: Fluoroborates, a specialized class of boron compounds, possess diverse and significant applications, including their use as flame retardant additives, catalysts, and optical materials. This study focused on determining the optimal synthesis parameters for nickel fluoroborate and investigating its applicability to cotton fabrics. Nickel fluoroborate was synthesized using a wet chemical method with nickel oxide (NiO) and fluoroboric acid (HBF 4 ) as reactants, where the key parameters investigated were the HBF 4 /NiO molar ratio, temperature, and reaction duration. The Response Surface Methodology (RSM) was employed for optimization, leading to the establishment of the following optimum synthesis conditions: a 4:1 molar ratio, a temperature of 90°C, and a duration of 100 minutes. Under these conditions, nickel fluoroborate was produced with a 98% yield and 89.5% purity, and the product was comprehensively characterized using Inductively Coupled Plasma-Optical Emission Spectroscopy (ICP-OES), Fluoroborate (BF 4 − ) ion-selective electrode, X-ray Diffraction Analysis (XRD), and Fourier Transform Infrared Spectroscopy (FT-IR). In the subsequent phase, the product’s application to cotton fabrics was assessed by treating samples with varying concentrations of the nickel fluoroborate solution for different immersion periods, with changes in the mass gain ratio being monitored. Crucially, the limiting oxygen index (LOI) test was performed, and the results conclusively demonstrated that the synthesized nickel fluoroborate exhibits excellent flame-retardant properties.
