دراسة تاثير اضافة مادة الزركونيا على بعض الخواص الفيزيائية والميكانيكية

Abstract EN

This research includes the study of the effect of zirconia (ZrO2) addition in a different weight percentages (5,10,15,20)% to porcelain samples formed from (Duekhla Kaolin, Ardima Sand, Feldspar Potash and Calcium Carbonate).

We studied effect of zirconia addition on some physical properties as (Linear shrinkage, bulk density, apparent porosity and water absorption) and mechanical properties as (Vickers hardness and indirect tensile strength).

The results shown that the zirconia addition in a percentage not increase (10%) have been enhanced the physical and mechanical properties of porcelain samples especially in indirect tensile strength.
