Description
Sodium Hexametaphosphate is inorganic phosphate dispersant. It features excellent adsorption and dispersion effect on alumina, corundum and mullite powder. It is widely used as dispersant for low cement castables, ultra-low cement castables and precast refractories. It adsorbs on particle surface, generates electrostatic repulsion, breaks agglomeration and optimizes flow performance. It reduces mixing water, lowers porosity and enhances fired strength. Suitable for neutral and acidic refractory systems. Custom purity grades are available.
