Calcium fluoride (CaF2) is used in aluminium-metallurgy, brake lining, glass manufacturing, enamel and glazing frits production, and the production of welding agents.

Calcium fluoride (synth.) is used in the the following applications:

  • Brake lining manufacturing: 
    Additive for high performance brake pads 

    The additive brake lining for the high temperature range: 

    • Synthetic calcium fluoride from Solvay guarantees uniformly high quality through the most careful selection of raw materials and extremely small manufacturing tolerances. Customised solutions for individual customer wishes and specific requirement profiles can be developed at the same time
    • Synthetic calcium fluoride from Solvay increases the comfort properties of the friction lining in the high temperature region (430 to 820°C); wear on the brake pads caused by adhesive abrasion is considerably reduced and the stability of the braking system is markedly increased
    • Synthetic calcium fluoride from Solvay ensures that the friction materials have extremely high thermal stability. This property is especially important when braking large masses and high speeds, e.g. high-speed trains or during aircraft landings
    • Synthetic calcium fluoride from Solvay improves depending on the composition thermal conductivity and reduces the formation of hot spots – thus prolonging the lifetime of the brake material
    • Synthetic calcium fluoride from Solvay is environmentally compatible – for example because of its minimal heavy metal content compared to natural fluorspar minerals
    • Synthetic calcium fluoride from Solvay ensures more enjoyment when driving – by a marked reduction in noise through squeak-free braking  
        
  • Production of welding agents: 
    As components in coatings of welding rods and welding powders
