Main Component: Calcium hydroxide (Ca(OH))
Purity: Typically, 95% to 99% pure calcium hydroxide
Appearance: White, fine powder
Odor: Odorless
Solubility: Slightly soluble in water; forms a milky suspension (lime water) when mixed
Bulk Density: Approximately 0.6 to 0.8 g/cmï
Calcium Oxide Content (CaO): Typically 70% to 75%
pH (0.1% Solution): Typically 12.4 to 12.8
Loss on Ignition: Generally less than 5%, indicating the amount of calcium carbonate or other impurities present
Mesh Size: Typically passes through a 100-mesh sieve (fine powder). Granulation can vary depending on the intended use.
Moisture: Usually less than 1% to 2% to ensure effective performance and prevent clumping.
Lead (Pb): Typically less than 10 ppm (parts per million)
Arsenic (As): Typically less than 5 ppm
Applications: Used in construction (as a lime mortar or plaster), water treatment (as a flocculant), soil stabilization, and in various chemical processes.
Storage Conditions: Store in a cool, dry place in sealed containers to prevent moisture absorption, which can cause caking or loss of reactivity.
Handling Precautions: Use appropriate personal protective equipment (PPE) such as gloves, masks, and eye protection, as the powder can be irritating to the skin, eyes, and respiratory system.
