Yittria Stablized Zirconia (YSZ- ) are extremely refractory materials. They possess excellent chemical inertness and corrosion resistance at temperatures up to 2200oC, well above the melting point of alumina. Zirconia are stabilized in the cubic crystal structure to avoid cracking and mechanical weakening during heating and cooling. In addition to their refractoriness, they offer low thermal conductivity and are electrical conductors above 800 oC. They also possess the unique ability to allow oxygen ions to move freely through the crystal structure above 600 oC. Max. Operation temperature: 2200 oC (no load) O.D: 50.8 mm (2") +/- 4% or +/-1.27 mm I.D: 41.92 mm (1-5/8") +/- 4% or +/-1.27 mm Length: 936 mm (36") Made in USA Warning & Tips The YSZ tube is very brittle and must be handled very carefully. When used as a processing tube, the heating and cooling rates should be as slow as possible (usually
