PRODUCT DESCRIPTION

FUSED CAST HIGH ZIRCONIA BLOCK

Descriptions

Our flagship fused cast high zirconia Blocks SR-Z95 represent the absolute pinnacle of high-temperature refractory technology. Specifically engineered to surpass the limits of standard AZS and 88% Zirconia refractories, this ultra-pure material is composed of a tightly interlocked 93% baddeleyite crystal matrix. It is designed with one goal in mind: to provide an impenetrable defense against chemical erosion in the most aggressive melting environments while guaranteeing zero contamination to the glass melt.

Advantages

l  Unmatched Corrosion Resistance: The 93% baddeleyite crystal framework delivers the industry's highest resistance to chemical erosion, thriving in environments that rapidly degrade conventional refractories. This drastically extends the service life of critical furnace zones.

l  Absolute Zero Contamination: Engineered with a near-zero glassy phase matrix, it completely eliminates the risks of exudation, bubbling, striae, or cord defects, securing maximum yields for high-end glass.

l  Extreme High-Temperature Resistivity: Demonstrates exceptional electrical insulation properties at elevated temperatures, making it immune to electrical breakdown in specialized melting environments.

l  Superior Structural Homogeneity: Produced via precise electric arc furnace melting and advanced fused casting, the block features a dense, uniformly packed microstructure that entirely prevents structural peeling, cracking, or thermal spalling.

Applications

Ultra-High Purity & Specialty Glass Melting

• TFT-LCD / OLED display glass substrates where microscopic defect control is critical.

• High-borosilicate glass and glass-ceramics that experience extreme chemical volatility.

• Optical glass and premium crystal requiring absolute clarity and flawless color purity.

Critical, High-Velocity Furnace Zones

• The Throat & Flow Channels: Endures continuous, high-velocity molten glass currents without erosive degradation.

• Hotspot Sidewalls & Fluid Lines: Withstands the maximum thermal concentration and chemical fluxing at the glass-air interface.

• Doghouse Corners & Feeders: Resists the intense mechanical abrasion and chemical attacks from raw batch materials.

Specialized Electro-Melting Electrode Blocks

• Due to its ultra-high electrical resistivity at temperatures exceeding 1600°C, it serves as the definitive electrode block material for advanced electric furnaces, maintaining zero conductivity even under strong electric fields
