📋 Article Overview
This guide is designed for industrial buyers, project managers, and procurement teams looking for reliable information about Caustic Calcined Magnesia. We follow industry standards to deliver transparent, accurate content aligned with 2026 global magnesia specifications.
What Is Caustic Calcined Magnesia?
Caustic Calcined Magnesia (CCM) is a highly reactive magnesia produced by calcining magnesite at 700–1000°C.
In practice, our production team at Jinghuang Nanomaterials controls the calcination temperature range precisely to retain the product's high reactivity, which is its key differentiator from lower-reactivity dead burned magnesia. 2026 industry data confirms that CCM is one of the most widely used magnesia products for industrial and agricultural applications globally.
Q: What is the main difference between CCM and dead burned magnesia?
A: The core difference lies in calcination temperature and reactivity. CCM is calcined at 700–1000°C with high reactivity, while dead burned magnesia is calcined at over 1500°C with low reactivity for refractory applications.业内共识,哦不对,英文,It is an industry consensus that CCM is more versatile for non-refractory use cases due to its reactive properties.
Key Properties & Purity Grades of Caustic Calcined Magnesia
Caustic Calcined Magnesia properties vary significantly by MgO purity, which dictates its suitable applications. Below is a comparison of common commercial grades we produce at Jinghuang Nanomaterials:
| MgO Purity Grade | Average Bulk Density (g/cm³) | Reactivity Level | Primary Applications |
|---|---|---|---|
| 80 – 85% MgO | 0.8 – 1.0 | Medium | Agricultural soil pH adjustment, animal feed additive |
| 85 – 90% MgO | 0.7 – 0.9 | High | Construction binder, wastewater treatment |
| 90 – 95% MgO | 0.65 – 0.8 | Very High | Chemical manufacturing, rubber manufacturing |
| 95%+ MgO | 0.6 – 0.7 | Extremely High | Environmental remediation, advanced industrial materials |

Actual testing from our quality control lab shows that even within the same purity grade, controlling impurity content (such as SiO₂ and CaO) is critical to meeting specific industry standards. We test every batch for impurities to ensure consistent performance for our clients.
Top Industrial Applications of Caustic Calcined Magnesia
Caustic Calcined Magnesia is used across dozens of industries due to its adjustable reactivity and neutralizing properties. Below is a step-by-step guide to selecting the right CCM for your project:
- Define your core performance requirement: confirm if you need CCM for pH neutralization, magnesium supplementation, or chemical feedstock.
- Specify required purity and maximum impurity limits based on your industry's regulatory standards.
- Request a small test sample from your supplier to validate reactivity and performance in your specific process.
- Finalize bulk order terms with clear quality specifications and certification requirements.
Q: Is Caustic Calcined Magnesia safe for agricultural use?
A: Recent 2026 agricultural research confirms that low-purity (80-85% MgO) CCM is safe for soil pH adjustment and magnesium supplementation for crops. It improves nutrient absorption and boosts crop yield in acidic soil when applied correctly, per industry guidelines.
Q: Can CCM be used for wastewater treatment?
A: Yes, 85-90% purity CCM is widely used to neutralize acidic industrial wastewater and remove heavy metals. From our customer cases, it delivers more cost-effective neutralization than other alkaline products for many wastewater treatment projects.
