Special Properties of Zirconia Beads
【High Melting Point】 Zirconia beads have a melting point of 2715 degrees Celsius. High melting point and chemical inertness make zirconia beads a better refractory material.
【High Hardness and Good Wear Resistance】The specific data shows that the Mohs hardness of zirconia beaded ceramics is about 8.5, which is close to sapphire 9, while the Mohs hardness of polycarbonate is 3.0, tempered glass is 5.5, and aluminum-magnesium alloy is 6.0, Corning Glass is 7.
【Low Thermal Conductivity and Expansion Coefficient】Among ordinary ceramic materials (1.6 ~ 2.03 w/(mk)), the thermal conductivity of zirconia microbeads is low, and the thermal expansion coefficient is close to that of metal.
Therefore, zirconia bead ceramics are suitable for the appearance and structural parts of structural ceramic materials such as zirconia bead ceramics.
