Lime is an indispensable raw material in the manufacture and processing of chemical substances and chemicals. Whether as a reaction partner, neutralising agent, precipitation reagent, pH stabiliser or functional filler – lump lime (CaO), hydrated lime (Ca(OH)₂) and calcium carbonate (CaCO₃) meet the highest requirements for purity, reactivity and consistency.
Why lime is indispensable in chemistry
Lime products are not only versatile in the chemical industry, but also technologically and economically indispensable. They enable controlled reactions, serve as a base supplier, neutralising agent and precipitation reagent, and contribute to the stabilisation of process parameters. Thanks to their defined reactivity and high purity, they ensure consistent product quality, support the efficiency of chemical syntheses and help to reliably comply with environmental regulations. Whether in organic or inorganic chemistry, in the formulation of reagents, in water treatment or in the manufacture of intermediate products – lime is a key raw material for safe, sustainable and economical processes.
Calmit’s lime products offer tailor-made solutions for the chemical industry, the manufacture of chemicals, the formulation of reagents, as well as for environmental technology and wastewater treatment.

Versatile applications in chemistry
Neutralisation & pH regulation: Hydrated lime is used efficiently and reliably for the neutralisation of acids and to stabilise the pH value in chemical processes.
Precipitation & purification: Lump lime and calcium hydroxide serve as proven precipitation reagents for the removal of heavy metals, phosphates and other undesirable substances.
Reaction partners in synthesis processes: Lime products are essential components of numerous organic and inorganic reactions, for example in the production of calcium compounds or as a carrier material for catalysts.
Fillers for chemical formulations: Precipitated calcium carbonate (PCC) acts as a functional filler in paints, varnishes, adhesives, plastics and rubber – it ensures targeted rheology, opacity, high whiteness and optimum mechanical properties.
Environmental technology & emission control: Hydrated lime is successfully used in flue gas desulphurisation (FGD), for binding HF/HCl and for stabilising chemical residues.
