Although geopolymerization does not rely on toxic organic solvents but only on water, it needs chemical ingredients that may be dangerous and therefore requires some safety procedures. Material Safety rules classify the alkaline products in two categories: corrosive products (named here: hostile) and irritant products (named here: friendly).[citation needed] The two classes are recognizable through their respective logos

Firstly, the ball mill is the grinding equipment after the material is broken; The crushing grain size of the material is very important before being grinded, so we can start from this aspect. Crushing the material into smaller particle size as much as possible before the materials into the ball miller, the solution is to configure a crusher with fine crushing granularity such as hammer mill, cone crusher or tertiary impact crusher, so that the material can also achieve the material granularity grinding requirements with short time, improve the ball mill production

The small negative Curie-Weiss temperature indicates the presence weak antiferromagnetic exchangeinteraction between the Ni magnetic centres. Indeed, the T curve (Fig. 6 left scale) shows a downward curvature, typical of systems with antiferromagnetic correlations and/or non-negligible spin-orbit coupling. The T=1.31 cm3.K.mol-1 at 310 K undergoes a small and gradual decrease to 1.19 emu.K.mol-1 at 24.5 K. The Curie constant value, either obtained by1/ linear fit or the T product for T>>p is in reasonable agreement with the expected spin-only theoretical value for NiII in octahedral environment with S=1 spin state (C = 1 cm3.K.mol-1and eff = 2.83 B considering g = 2) for unquenched orbital moment C = 3.91 cm3.K.mol-1and eff = 5.59 B).
