Magnesium Sulphate Anhydrous Granular(100% water solute)
Magnesium Sulphate Anhydrous Powder (MgSO₄) is the most concentrated and purest commercially available form of magnesium sulfate, entirely free of water of crystallization. It is a fine, white, free-flowing powder characterized by its exceptionally high magnesium content (≥ 33% as MgO). This product is engineered for advanced industrial applications and specialized formulations where the highest purity, maximum reactivity, absolute moisture control, and precise chemical composition are non-negotiable requirements, such as in high-end pharmaceuticals, catalyst systems, and specialized chemical synthesis.

Core Features & Competitive Advantages
Ultimate Purity & Maximum Concentration
· SHighest Magnesium Content: Delivering ≥ 33% MgO (Magnesium Oxide equivalent), it offers the most potent source of magnesium per unit weight, maximizing efficiency and minimizing the addition rate in formulations.
· 100% Anhydrous: Contains zero water of crystallization (< 0.5% moisture), eliminating any risk of water interference in sensitive chemical reactions or hygroscopic processes. This is its defining advantage over mono- and heptahydrate forms.
Superior Chemical & Physical Properties
· High Reactivity & Purity: The absence of water molecules allows for direct and predictable participation in chemical reactions, making it a preferred raw material for synthesis where stoichiometry and purity are critical.
· High Reactivity & Purity: The absence of water molecules allows for direct and predictable participation in chemical reactions, making it a preferred raw material for synthesis where stoichiometry and purity are critical.
Excellent Flowability & Consistency: Produced as a uniform fine powder with outstanding handling properties, ensuring precise dosing and homogeneous blending in high-value manufacturing.
Unmatched Stability for Demanding Processes
· Non-Hygroscopic Core Stability: Unlike hydrated forms, it does not absorb moisture from the air under normal conditions, providing unmatched stability for long-term storage and in formulations prone to degradation by water.
· Thermal Stability: Maintains its chemical integrity over a wide temperature range, suitable for processes involving elevated temperatures.
Magnesium Sulphate Anhydrous Granular
Unrivaled Storage & Process Stability
· Absolute Moisture Independence: Its anhydrous nature guarantees no weight loss due to water evaporation and no change in chemical composition during storage or under vacuum/heat in processes, ensuring batch-to-batch consistency.
· Compatibility with Water-Sensitive Systems: It is the only suitable magnesium sulfate grade for use in anhydrous solvents, moisture-sensitive catalytic reactions, and formulations where even trace water is detrimental.
Precision Functional Performance
· As a High-Purity Reagent: Functions as a precise source of Mg²⁺ and SO₄²⁻ ions in analytical chemistry, molecular biology, and pharmaceutical synthesis without introducing unknown variables from water content.
· As a Drying Agent & Catalyst Support: Utilized for its ability to absorb traces of water in organic synthesis and as a high-surface-area support for catalysts in various industrial processes.

Applications & Solutions
Compound Fertilizer Production
Application: A key ingredient in dry-process NPK/Mg/S compound fertilizer formulations. Dosage varies from 2-10% depending on the crop-specific formula.
Benefit: Provides a consistent, dust-free, and highly concentrated source of magnesium and sulfur that integrates perfectly into granular fertilizers, improving nutrient balance and crop quality.
Animal Feed Premix & Concentrates
Animal Feed Premix & Concentrates
Application: Precisely blended into mineral premixes, vitamin-mineral concentrates, and complete feeds for poultry, swine, ruminants, and aquaculture.
Benefit: Ensures accurate and uniform distribution of essential magnesium in feed, supporting animal health and productivity without affecting the shelf life or flowability of the premix.
Technical & Industrial Uses
Application: Used in chemical synthesis, as a drying agent, in the production of specialty chemicals, and in wastewater treatment where a concentrated magnesium source is required.
Benefit: Offers high chemical purity and reactivity, making it a reliable raw material for demanding industrial processes.

FAQ
Q1: What is the key advantage of Monohydrate over Heptahydrate for my feed or fertilizer factory?
A: The primary advantages are higher nutrient concentration (saving on storage and freight), low moisture content (prevents caking and preserves blend stability), and superior flowability (ensures precise dosing and mixing in automated systems). It is the professional choice for dry blending processes.
Q2: Can Magnesium Sulphate Monohydrate be used for foliar spray applications?
A: While highly soluble, the Monohydrate powder is primarily engineered for dry blending. For foliar sprays, the Heptahydrate (Epsom Salt) form is often preferred due to its faster dissolution in small volumes of water. However, Monohydrate can be used if fully dissolved in a stock solution first.
Q3: How does your Magnesium Sulphate Monohydrate ensure consistency for large-scale feed production?
A: Our product is characterized by consistent particle size and exceptional flowability. This prevents segregation in silos and ensures that the same precise amount of magnesium is delivered into every ton of feed, which is critical for animal health and meeting nutritional specifications.
