In Germany’s advanced refractory industry, the demand for silica fume has grown rapidly due to its exceptional performance in enhancing durability, thermal resistance, and mechanical strength. Among different grades, 98% Fume di silice non intensificato has become one of the most trusted materials for refractory applications in Germany. A Henan Superior Abrasives (HSA), we supply high-purity silica fume that meets the stringent quality requirements of German manufacturers, ensuring consistency and reliability in every batch.
What is Silica Fume and Why It Matters in Refractory Materials?
Silica fume, also known as microsilica, is an ultrafine by-product from the production of silicon and ferrosilicon alloys. Its particles are about 100 times smaller than cement grains, giving it a unique ability to fill microscopic voids in refractory mixes.
In refractory materials, silica fume contributes to:
- Improved density – minimizing porosity and enhancing compactness.
- Higher strength – both at room temperature and at high thermal exposure.
- Reduced permeability – lowering the penetration of slag and molten metals.
- Extended lifespan – ensuring longer service cycles in harsh industrial environments.
For German refractory manufacturers, where efficiency and quality are key, silica fume for refractory materials is indispensable.
Why 98% Undensified Silica Fume is Preferred in Germany
While densified and undensified grades of silica fume are available, 98% Il fumo di silice non intensificato è particolarmente prezioso nella produzione refrattaria. Ecco perché:
Purezza ultra-alta
Con un contenuto di Sio₂ di over 98%, Fume di silice non intensificato offre la massima stabilità chimica. Le industrie tedesche danno la priorità alle materie prime ad alta purezza per garantire prestazioni coerenti e minime impurità nei rivestimenti refrattari.
Ottima capacità di imballaggio
Essere in una forma intensificata, Questo fume di silice ha una dispersibilità superiore. Si fonde agevolmente con miscele refrattarie, riempire i micro-danni in modo più efficace dei tipi densificati, which is critical for applications requiring extreme density.
Enhanced Thermal Resistance
Refractories enhanced with 98% Undensified Silica Fume withstand temperatures above 1600°C, making them suitable for steel, cement, glass, and non-ferrous metal industries in Germany.
Reduced Permeability and Slag Attack
German steel and foundry industries often face aggressive slags and molten metal penetration. The addition of silica fume minimizes permeability, preventing chemical attack and extending refractory life.
Applications of Silica Fume for Refractory Materials in Germany
Germany is home to one of Europe’s most advanced refractory sectors, supplying products to steel plants, cement kilns, glass furnaces, and non-ferrous smelters. Silica fume is widely used in:
Steel Industry
High-purity 98% Undensified Silica Fume is used in gunning mixes, castables, and ramming materials for steel ladles, tundishes, and blast furnaces. Its ability to resist slag erosion ensures long service life.
Cement Industry
Cement kilns in Germany operate under extreme conditions. Adding silica fume to refractory linings increases thermal resistance and reduces clinker infiltration.
Glass Manufacturing
In glass furnaces, where temperatures exceed 1500°C, silica fume provides stability and minimizes structural cracks in refractory linings.
Non-Ferrous Metal Smelting
For copper, aluminum, and nickel smelters in Germany, silica fume improves resistance against chemical corrosion and thermal shock.
Comparing Densified vs. Fume di silice non intensificato
Both densified and undensified silica fume are widely used in construction and refractory industries. However, their applications differ:
- Fume di silice densificato (G85D–G98D): Easier to transport and handle, mainly used in concrete applications.
- Fume di silice non intensificato (G85U–G98U): Ideal for refractories due to better particle dispersion and improved microstructure.
For German refractory manufacturers, 98% Undensified Silica Fume remains the top choice for achieving maximum strength and durability.
