Method For Enhancing Mechanical Properties In Sintered Ceramic Bodies Having Applications In Dental Restorations
A method for enhancing mechanical properties of sintered, zirconia ceramic bodies and zirconia ceramic dental restorations is provided. A porous or pre-sintered stage of a ceramic body may be treated with a tantalum-containing composition prior to sintering. Alternatively, zirconia ceramic powder may be coated with a tantalum-containing composition prior to forming a shaped ceramic body. After sintering, the resulting ceramic bodies have enhanced mechanical properties, such as greater fracture toughness, without a significant decrease in optical properties.
