Mozambique Zirconia ceramic sieve plate

Zirconia ceramic sieve plate with ZrO2 as the main component, according to the addition of stabilizers, mainly yttrium stabilized zirconia, magnesium stabilized zirconia and cerium stabilized zirconia. Zirconia ceramics usually have high mechanical strength and fracture toughness, and have good corrosion resistance. Magnesium stabilized zirconia still maintains good mechanical properties at high temperature (600 ℃).

Product Description

Zirconia ceramics are mainly composed of ZrO2, and according to the added stabilizer, there are mainly yttrium stabilized zirconia, magnesium stabilized zirconia and cerium stabilized zirconia. Zirconia ceramics usually have high mechanical strength and fracture toughness, and have good corrosion resistance. Magnesium stabilized zirconia still maintains good mechanical properties at high temperature (600 ℃).
