Inside Mullite / Part 3: How It’s Used
You may not recognize mullite by name, but chances are you've benefited from it. From dinner plates and car parts to rocket engines and industrial furnaces, mullite is a high-performance material that makes modern manufacturing possible.
How is Mullite Used?
Mullite’s strength at high temperatures, resistance to thermal shock and chemical attack, and low impurity levels make it ideal for:
● Refractories – Linings for kilns, furnaces, and incinerators.
● Ceramics – Structural and technical ceramics requiring durability and heat resistance.
● Electrical Insulators – High-voltage components needing reliable insulation.
● Heating Elements – Components exposed to extreme heat in industrial equipment.
● Brake Shoes – Resists heat and friction in braking systems.
● Foundry Sprays and Washes – Enhances mold performance and surface finish.
● Investment Casting – Used in flours and stuccos for precision shell building.
● Kiln Furniture – Often combined with cordierite for added strength and thermal efficiency.
● Aerospace – Our mullite was even used in early NASA trials!
Why Virginia Mullite®?
Our Virginia Mullite® is REACH compliant (EU), giving customers confidence in its safety, quality, and regulatory transparency. We don’t add chemicals or alter the material’s essential nature—instead, we remove impurities and apply heat to force a natural phase transformation, producing a clean, consistent mullite product that performs under pressure.
With low impurity levels that reduce metal-mold reactions and enhance creep resistance, Virginia Mullite® delivers the purity and reliability manufacturers depend on in high-stakes, high-temperature environments.
