Fused Zirconia Mullite

Fused Zirconia‑Mullite Features

1、Dense fused crystalline structure
Electric‑arc fused manufacturing delivers low apparent porosity, high bulk density, excellent volume stability under high temperature.
2、Superior high‑temperature performance
High refractoriness, service temperature up to 1650‑1700℃, low high‑temperature creep, keeps structural integrity under long‑term heavy thermal load.
3、Outstanding corrosion & penetration resistance
Excellent resistance to molten glass, alkaline vapors and slags. Resist melt penetration, reduce contamination risk for glass products, ideal for severe corrosive zones.
4、Excellent thermal shock resistance & spalling resistance
Zirconia phase toughening effect, good stability under rapid temperature fluctuation, less cracking and peeling during furnace start‑stop cycles.
5、High mechanical strength at room & elevated temperature
High cold crushing strength and hot modulus of rupture, great load‑bearing capacity for heavy‑duty furnace linings and skid rail applications.
6、Good wear resistance
Resist scouring from high‑speed flue gas and molten material flow, extend service life of key furnace parts.
7、Custom shapes & dimensions available
Custom‑cast or pre‑cut bricks for glass furnace, metallurgical kiln, waste incinerator and other industrial high‑temperature equipment

Fused Zirconia-Mullite can be used as filler in refractory applications, ceramic glaze to improve its thermal shock resistance, or glass polishing agents. The use of fused zirconia-mullites makes it possible to reduce production costs while maintaining performance levels comparable with traditional materials such as magnesia and alumina.

Refractory Grade FZM:
Refractory grade fused zirconia-mullite is used for the manufacture of high-temperature refractories and ceramic fiber products. It finds its applications in various industries such as glass, steel, metallurgy, petroleum refining, and so on. The growing demand from these end-user industries like the petrochemical sector is projected to drive market growth over the forecast period.

Ceramic Grade FZM:
The ceramic grade is a class of ultra-high purity fused zirconia (UHPZ), which can be used in the form of ceramics. These are made from UHP ZrO and produce ceramic disks with high density, low porosity, and extremely low metal ion content for use as substrates to grow oxide thin films and epitaxial layers on them. It has been widely used as an intermediary material for the diffusion barrier layer when fabricating multilayered electronic devices by chemical vapor deposition or atomic layer deposition processes.
On the basis of Application, the market is segmented into Glass, Steel, Refractories, and Electronics.

Glass Grade FZM:
The glass industry is the main end-use of fused zirconia-mullite. It finds application in various products such as building materials, electrical appliances, etc. Glass sector is one of the growing industries due to its wide range of applications across various sectors like construction and real estate.

Steel grade FZM:
Fused Zirconia-Multis are used by steel plants for blending with other raw materials during the sintering process or before casting metal into ingots billets. This material can be used as a refractory material that can withstand high temperatures. Refractories are widely used in the steel industry to protect the furnace and other equipment from damage by abrasion, wear, erosion or corrosion due to molten metal contact.

Refractories Grade:
Fused Zirconia-Multis are extensively used as filler materials for ceramic fiber production like insulation boards and corrugated sheets. Ceramic Fibers manufactured using this product have excellent thermal shock resistance properties compared with alumina fibers.
