Calcium Hydroxide CAS No: A Key Chemical in Industry and Beyond
When you hear calcium hydroxide CAS no, it might sound like something strictly for chemists or manufacturers, but frankly, its impact stretches far and wide — across industries, humanitarian efforts, and environmental solutions. Understanding this compound and its unique identifier, the CAS number, is more than just a technical exercise; it’s a dive into a chemical that’s quietly essential to everything from water treatment to construction.
Why Calcium Hydroxide Matters Globally
Globally, calcium hydroxide is a staple chemical in industrial applications and everyday products. According to the World Bank, alkaline chemicals like calcium hydroxide underpin many water purification processes, improving billions of lives by making drinking water safe. The calcium hydroxide cas no (CAS number 1305-62-0) specifically helps scientists and professionals universally identify the compound, eliminating confusion and improving supply chain efficiency worldwide.
Oddly enough, this simple “slaked lime” reduces acidic waste, neutralizes soil pH in agriculture, and even supports eco-friendly construction. But it also comes with challenges — handling safety, sourcing quality products, and balancing environmental concerns. So, why do we keep coming back to it? Because it works, and it’s relatively affordable.
What Is Calcium Hydroxide? A Simple Definition
Put plainly, calcium hydroxide is a white powder or crystal formed by treating calcium oxide with water — hence “slaked lime.” It’s widely used in numerous industries: as a pH adjuster, in cement production, and in chemical manufacturing. Its chemical formula is Ca(OH)2, and the CAS number helps chemists worldwide track and buy the right stuff without mix-ups.
This compound plays a silent but profound role in industrial systems and humanitarian efforts — like stabilizing soils in disaster-hit communities or purifying water supplies in remote regions.
Key Factors about Calcium Hydroxide CAS No
1. Purity and Quality
Industries require calcium hydroxide with specific purity levels – impurities affect its performance. Variants tailored for food-grade use differ from those intended for industrial applications, making the CAS number and associated specs crucial for buyers.
2. Solubility and Reactivity
Its limited solubility in water means it’s perfect for controlled chemical reactions like neutralization. This characteristic is useful, for example, in treating acidic soils or adjusting wastewater pH.
3. Storage and Handling Needs
Calcium hydroxide can absorb CO₂ from the air, gradually converting to calcium carbonate — which affects effectiveness. So, proper dry storage and airtight packaging are essential, especially for large-scale industrial users.
4. Environmental Impact
Despite some CO₂ release during early production steps, calcium hydroxide application can improve soil health and reduce contaminants in water, contributing to sustainability in agriculture and industry.
5. Versatility
Its ability to serve countless functions — for example, in manufacturing plasterboard, producing sugar, or flocculating sewage — makes it valuable across sectors and geographies.
Global Applications and Real-World Use Cases
Across Asia and Africa, calcium hydroxide cas no-identified products are a mainstay in water treatment plants that make safe drinking water accessible in rural and underdeveloped regions. Post-disaster relief organizations use it for soil stabilization and water quality restoration. In Europe, factories rely on it for flue gas treatment to reduce industrial emissions, helping meet strict ISO standards.
To paint a clearer picture:
- In remote industrial zones: Calcium hydroxide serves to neutralize acidic wastes from mining, protecting groundwater.
- In agriculture: Farmers apply it to regulate soil pH, increasing crop yields sustainably.
- Textile industries: Use it in the bleaching process, helping maintain fabric quality.
In all these cases, the traceability supported by properly referencing the CAS number ensures industries get the right product, avoiding costly mistakes.
Mini takeaway:
Calcium hydroxide isn’t just a niche chemical — it’s foundational for diverse sectors worldwide, often working behind the scenes.
Advantages and Long-Term Value
From a practical perspective, calcium hydroxide offers cost efficiency — it’s relatively inexpensive to produce compared to alternatives. Its environmental benefits, such as aiding carbon capture indirectly when used in soil improvement, add to its sustainability profile. Plus, it evokes trust: longstanding safety data, wide regulatory acceptance, and proven performance mean companies and communities alike rely on it.
Emotionally speaking, there’s comfort knowing products derived from calcium hydroxide contribute to safe water and stable infrastructure. It rewards with innovation opportunities, too — from green construction practices to emerging uses in carbon sequestration technologies.

Future Trends and Innovations
The calcium hydroxide landscape is evolving. There’s a growing emphasis on sustainable production methods to reduce initial CO₂ emissions. Researchers are exploring its role in carbon capture technologies, essentially turning it into a tool against climate change. The integration of digital supply chain management ensures better tracking of quality and origin, linking directly back to its CAS number identification.
Automation in manufacturing promises consistent quality with less waste, while new applications in bioengineering hint at uses we haven’t fully realized yet. So, next time you read a safety data sheet, you might imagine a future where calcium hydroxide also plays a key role in green energy solutions.
Challenges and How to Overcome Them
Handling calcium hydroxide safely requires training – it’s alkaline and can irritate skin or eyes. Storage conditions can degrade quality if not carefully controlled. Plus, scaling eco-friendly production without increasing costs is tricky.
Experts recommend investing in continuous quality control, sourcing from certified vendors, and innovating packaging to reduce exposure to moisture and CO₂. Ultimately, aligning industrial priorities with sustainability goals will be key.
FAQ: Frequently Asked Questions About Calcium Hydroxide CAS No
- What is the significance of the CAS number 1305-62-0 for calcium hydroxide?
- The CAS number uniquely identifies calcium hydroxide globally, ensuring clarity in chemical supply and safety documentation. It prevents confusion with similar compounds, which is crucial for compliance and quality control.
- How should calcium hydroxide be stored to maintain its effectiveness?
- Store calcium hydroxide in airtight, moisture-proof containers away from CO₂ exposure. Cool, dry environments prevent it from absorbing carbon dioxide, which would convert it to calcium carbonate, thus reducing purity.
- Is calcium hydroxide safe for use in water treatment?
- Yes, when used properly, it’s effective and safe. It raises water pH, neutralizing acidity and aiding contaminant removal. However, dosing must be controlled to avoid over-alkalization.
- Can calcium hydroxide be used in food-related applications?
