Introduction to Slaked Lime – Ip Grade
Slaked Lime – Ip Grade is a highly purified form of calcium hydroxide used in pharmaceutical, food, and specialized industrial applications. Because it meets strict quality standards under the Indian Pharmacopoeia (IP), it is considered safe for medical and regulated uses.
If you’re searching for Slaked Lime – Ip Grade for business, manufacturing, or supply purposes, understanding its properties, benefits, and standards is essential. Let’s break it down in simple terms.
What is Slaked Lime?
Slaked lime is chemically known as calcium hydroxide (Ca(OH)₂). It is produced when quicklime (calcium oxide) reacts with water in a controlled process.
Chemical Composition and Formula
-
Chemical Name: Calcium Hydroxide
-
Chemical Formula: Ca(OH)₂
-
Molecular Weight: 74.09 g/mol
-
Appearance: White powder
-
Odor: Odorless
-
Solubility: Slightly soluble in water
When mixed with water, it forms limewater — a mild alkaline solution.
Manufacturing Process
The process is simple but must be carefully controlled:
-
Limestone (CaCO₃) is heated to produce quicklime (CaO).
-
Quicklime reacts with water.
-
This reaction forms calcium hydroxide.
-
The material is then purified and tested for IP compliance.
For IP Grade material, the purification and testing stages are extremely strict.
Understanding IP Grade Standards
What Does IP Stand For?
IP stands for Indian Pharmacopoeia, which sets quality standards for medicines and pharmaceutical ingredients in India.
