Mechanical properties and in vitro bioactivity of silicon nitride ceramics with SiO2 , CaO, and MgO additions
{{output}}
Silicon nitride ceramics with SiO2 , CaO, and MgO as sintering aids were investigated in view of biomedical applications. In the current study, samples with four different compositions were pressureless sintered at 1750°C for 1 h under a nitrogen atmosphere. ... ...
