AB  - Zirconium diboride(ZrB2) belongs to the group of ultrahigh temperature ceramics (UHTCs) because of its high melting point (3250°C). Due to its excellent properties, such as the melting temperature, high strength and hardness, high thermal and electrical conductivities relative to other ceramics and good corrosion resistance to molten metals, it has attracted great interest from materials scientists. Fully dense ZrB2 ceramics were successfully obtained by hot pressing at 2150oC for 10 minutes. Prior to hot pressing, commercially available ZrB2 powder was ball milled for 24hr with ZrB2 media. Carbon was added as a densification aid in the amount of 0.5 wt.% using phenolic resin. For mechanical testing, three different methods were compared. Three point bending was performed in air at room temperature and the obtained strength was 546±55 MPa. Four-point bend strengths were measured under same conditions resulting in strengths of 476±112 MPa. Finally, the fracture toughness of pure ZrB2 ceramics was determined by the chevron notched beam method to be 4.1 ± 0.5 MPa•m1/2. The obtained results of mechanical testing make this ceramic material applicable as cutting tools, and parts for hypersonic aerospace vehicles.
