Industrial-grade sodium nitrate high-performance oxidant and efficient nitrogen source.

Sodium nitrate (NaNO₃), as a crucial inorganic compound, is an indispensable raw material in numerous industrial processes. From glass manufacturing to metal processing, its unique chemical properties enable it to occupy a core position in the global industrial chain. This guide will deeply analyze the professional knowledge of sodium nitrate to help you make a wise purchasing decision for your next project.

What is sodium nitrate?

Sodium nitrate, commonly known as Chilean nitrate, is a white to light gray crystalline powder composed of sodium ions (Na⁺) and nitrate ions (NO₃⁻). It is renowned for its strong oxidizing property and high water solubility, and is a fundamental chemical in the fields of agriculture and industry.

Key physical and chemical properties.

High Purity: The purity of our products typically ranges ≥99.4%, with high-purity grade products reaching ≥99.9%, ensuring consistent reactions and final product quality.
Strong oxidizing property: It can decompose and release oxygen at high temperatures, making it an ideal combustion aid for many combustion and metallurgical processes.
High-efficiency nitrogen source: Provides nitrate nitrogen (NO₃-N) that can be directly utilized by plants and chemical reactions.
Solubility: Readily soluble in water, facilitating use in liquid formulations and processes.
Hygroscopicity: It will absorb moisture in a humid environment and should be stored under dry conditions.
Melting point: Approximately 308°C, decomposes.

The diversified industrial applications of sodium nitrate

The glass manufacturing industry

Oxidant: Prevents sulfides in the furnace from forming ferrous sulfide, thereby avoiding the green color of the glass and producing purer and brighter glass.
Clarifying agent: The oxygen released during high-temperature decomposition helps remove bubbles from the glass melt.
Toner: When combined with other chemicals, it can be used to adjust the final color of glass.

Metal processing industry

In metal processing, sodium nitrate (often mixed with sodium nitrite) is a key component in salt bath heat treatment:

Quenching and tempering: Provide a uniform heating medium to prevent metal oxidation and decarburization.
Quenching and tempering: Provide a uniform heating medium to prevent metal oxidation and decarburization.

High-quality oxidants for the chemical and fireworks manufacturing industries

Chemical synthesis: As a raw material for the production of other nitrates (such as potassium nitrate), dyes, drugs and explosives.
Fireworks and propellants: As an oxidizing agent, it provides oxygen for fireworks, firecrackers and certain solid rocket propellants, supporting combustion.

Fast-acting nitrate nitrogen fertilizers in the agricultural field

Rapid nitrogen supplementation: Nitrate nitrogen can be directly absorbed by crops without soil transformation, and the effect is quick.
Chlorine-sensitive crops: Suitable for crops such as tobacco and citrus that are sensitive to chloride ions.
Low-temperature environment: When the soil temperature is relatively low, nitrification is slow, and sodium nitrate becomes an effective nitrogen source.
