Industrial grade Usage:
1. In ceramic applications, sodium hexametaphosphate (SHMP) can be
used as a dispersant and an anti-flocculant in clay and ceramic
suspensions. It helps to improve the flow properties and stability
of the clay paste, making it easier to use in the ceramic
manufacturing process.
2. Sodium hexametaphosphate can be heated with sodium fluoride to
produce sodium monofluorophosphate, which is an important
industrial raw material.
3. Sodium hexametaphosphate in the paper making, textile, printing
and dyeing, petroleum chemical, metallurgy and construction
material industries as a water softener, flotation agent,
dispersing agent and high temperature adhesive.
4. Sodium hexametaphosphate is widely used as scale inhibitor in
the water treatment industry.
