Lime Powder – Complete Industrial Description

Type: Calcium-Based Alkaline Mineral Powder
Appearance: White to Off-White Fine Powder
Application: Construction, Water Treatment, Agriculture, Chemical Industry, Soil Stabilization

Lime Powder is a finely processed calcium-based material mainly derived from limestone or quicklime hydration. It is widely used in construction, agriculture, water treatment, and various industrial processes due to its strong alkaline properties, chemical reactivity, and cost-effectiveness. Lime Powder plays a vital role in improving soil quality, neutralizing acidity, and supporting multiple chemical reactions in industrial systems.

Its high reactivity, versatility, and wide availability make it one of the most important industrial minerals used globally.


Product Overview

Lime Powder is produced by processing limestone (CaCO₃) through calcination to form quicklime (CaO), which is then hydrated to produce calcium hydroxide [Ca(OH)₂], commonly known as hydrated lime or lime powder.

Depending on the production method and application, Lime Powder is available in different grades such as industrial grade, construction grade, and agricultural grade.

It is widely used as a low-cost, highly effective chemical agent in multiple industries.


Chemical Composition and Properties

Lime Powder mainly consists of calcium hydroxide, a strong alkaline compound.
