Description

Nitric Acid, Calcium Salt, Hydrate (2:7) is a specific hydrated form of calcium nitrate, a highly soluble inorganic salt. This compound is valued for its dual role as a powerful oxidizing agent and a source of both calcium and nitrate ions. It is primarily required by industries involved in chemical synthesis, pyrotechnics, and specialized agriculture, where controlled oxidation or nutrient delivery is critical.

Application

• As a strong oxidizing agent in various chemical synthesis and manufacturing processes.
• Component in specialty fertilizers and nutrient solutions for hydroponics and greenhouse cultivation.
• Raw material in the production of pyrotechnics and explosives, where it acts as an oxidizer.
• Used in wastewater treatment processes for odor control and as a nitrogen source.
• Precursor in the manufacture of other calcium compounds and nitrate salts.
• Application in concrete set accelerators and other construction chemicals.
• Laboratory reagent for analytical chemistry and research purposes.

Quality Control

Our Nitric Acid, Calcium Salt, Hydrate (2:7) is manufactured under a strict quality management system. Each batch undergoes rigorous analytical testing to ensure it meets precise chemical and physical specifications. A comprehensive Certificate of Analysis (COA) detailing purity, assay, and impurity profiles is available for every shipment to guarantee traceability and consistency for your critical applications.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated area away from incompatible materials such as combustible substances, reducing agents, and strong acids. Due to its hygroscopic nature, the container must be kept tightly sealed to prevent moisture absorption and caking. Recommended storage temperature is 15-25°C.
