Qualitäten von Magnesiumverbindungen, nebeneinander verglichen

High Purity Magnesium Oxide ZH-V2

≥ 99,7% · ≤ 0,03%

Our highest-assay magnesium oxide: 99,7% MgO minimum, with CaO, chloride and iron held low enough for electronic ceramics and soft magnetic ferrite. Choose it when trace impurities, not reactivity, are the risk.

High Purity Magnesium Oxide ZH-V3H

≥ 99,5% · ≤ 0,025%

A 99,5% high purity magnesium oxide for applications that need purity and reactivity together — rubber vulcanisation, pharmaceutical and food formulations, fine-chemical synthesis. Move to ZH-V2 when iron and calcium become the constraint.

Active Magnesium Oxide ZH-M600

≥ 99% · ≤ 0,2%

High-activity magnesium oxide with a specific surface area of at least 175 m²/g. A high-functionality fine inorganic material: adsorbs more, cures faster and reinforces more per kilogram than a dense grade.

Active Magnesium Oxide ZH-V150

≥ 99% · ≤ 0,2%

Active magnesium oxide at 150 m²/g — one step below ZH-M600 on reactivity, one step above it on bulk density and handling. Choose it when 175 m²/g makes the powder too dusty or too fast for the line.

Food & Pharmaceutical Grade Magnesium Oxide

Produced, handled and packed separately from industrial grades, with lead, arsenic, cadmium and mercury reported on every batch COA. Used as an acidity regulator, an antacid and a magnesium nutrient source.

Industrial Grade Magnesium Oxide

General-purpose MgO where the application does not see trace CaO, chloride or iron. Used for neutralisation, pH control and general industrial processing.

Light Magnesium Oxide

Calcined at a lower temperature than heavy MgO, leaving a low bulk density and a high specific surface area. Reacts faster and occupies more volume per kilogram — the conventional choice for rubber, and the wrong choice if your process is volume-limited.

Heavy Magnesium Oxide

Dense and free-flowing MgO. Used where the material has to be weighed, conveyed and filled without dusting, and in technical ceramic bodies.

Nano Magnesium Oxide

Nano-scale magnesium oxide for catalyst supports, electronic ceramics, thermally conductive fillers, antibacterial use and fine-inorganic precursors. Parameter data is incomplete — do not publish until particle size, surface area and crystal form are measured. Civilian applications only (rule H6) — the red-line word list lives in site/src/i18n/_glossary.md and is enforced by an assertion in this script.

Industry-Specific Magnesium Oxide

MgO cut to a single customer process — purity, particle-size distribution, bulk density and surface area set to the values your formulation needs.

Analytical Reagent Grade Magnesium Oxide

Reagent-grade MgO for laboratory analysis, supplied with the impurity data the analysis depends on.

High Purity Magnesium Hydroxide ZH-H1

High purity magnesium hydroxide. High activity and high dispersibility let it compound into polymers easily, so it works as a functional filler and as a precursor to high purity MgO — where a hydroxide route disperses better in the process than a pre-calcined oxide.

High Purity Magnesium Hydroxide ZH-H2

≥ 99% · ≤ 0,35%

High purity magnesium hydroxide at 99% minimum, with acid insoluble matter held to 0,07% and chloride to 0,35%. Sits alongside ZH-H1 for electronic and functional materials; the two differ in impurity limits and bulk density, not in chemistry.

High Purity Magnesium Hydroxide ZH-H3

≥ 99% · ≤ 0,5%

High purity magnesium hydroxide, third step in the H series. Held at P1 deliberately: H1/H2/H3 differ too little to publish all three without thin content.

Flame Retardant Magnesium Hydroxide

Built for low-smoke zero-halogen compounds: decomposes endothermically above 300 °C, releases water vapour rather than toxic or corrosive gas, and is surface-treated so it disperses in polyolefins without overloading the formulation with coupling agent.

Surface-Modified Magnesium Hydroxide

Mg(OH)₂ with a stearate, silane or customer-specified surface treatment, for compounds where dispersion and mechanical-property retention decide the formulation.

Food & Pharmaceutical Grade Magnesium Hydroxide

Produced, handled and packed separately from industrial grades, with lead, arsenic, cadmium and mercury reported on every batch COA. Used as an antacid and a magnesium source.

Industry-Specific Magnesium Hydroxide

Mg(OH)₂ cut to a single customer process — purity, particle size, surface treatment and loading behaviour set to your formulation.

High Purity Magnesium Carbonate

Specified where trace calcium, chloride and iron would show up in the fired body or the final formulation. The carbonate route to MgO for electronic ceramics, and a controlled magnesium source for fine-chemical use.

Basic Magnesium Carbonate

The hydrated form of MgCO₃, with a higher loss on ignition than the normal grade. Decomposes to MgO on firing, which is why it is used as a ceramic precursor — and its fine, bulky structure is why rubber and flame-retardant compounders use it as a reinforcing filler.

Light Magnesium Carbonate

≥ 42,9% · ≤ 0,01%

The low-bulk-density, high-specific-volume form of MgCO₃: very fine, bulky, easy to disperse. Used for rubber reinforcement and as a carrier and anti-caking agent in food and pharmaceutical powders.

Industrial Grade Magnesium Carbonate

General-purpose MgCO₃ for industrial filling and processing use.

Heavy Magnesium Carbonate

Dense and free-flowing MgCO₃ for technical ceramic bodies and for volume-limited filling.

Food & Pharmaceutical Grade Magnesium Carbonate

Anti-caking agent, carrier, acidity regulator and magnesium fortification, with heavy metals reported on every batch COA.

Industry-Specific Magnesium Carbonate

MgCO₃ cut to a single customer process — bulk density, particle size and loss on ignition set to your line.
