5mol, 8 mol Zirconia pipe

Our factory specializes in producing 8 mol% yttria-stabilized zirconia ceramic tubes. We use high-purity raw materials, isostatic pressing, and high-temperature precision sintering, resulting in high density, excellent ionic conductivity, long-term high-temperature resistance, thermal shock resistance, corrosion resistance, insulation, and wear resistance, with stable dimensional accuracy.

We can make tubes that are open at both ends, closed at one end, or thin-walled, with outer diameters of 5–50mm and customizable lengths. 

They are widely used in oxygen sensor probes, thermocouple protection tubes, solid oxide fuel cells, high-temperature furnace tubes, temperature measurement in metallurgy and chemical industries, semiconductor equipment, and more. Factory direct sales, support for custom designs, small batch orders accepted, fully inspected before delivery, stable lead times, and reliable quality.
