Cyanate ester resin (CE)/silicon nitride (Si3N4) composites with high fracture toughness, strength and excellent dielectric properties, were fabricated by pressureless sintering and infiltration. The composites possessed excellent mechanical properties. The fracture toughness and strength of the composite are 4.2MPam1/2 and 233MPa respectively. The composites possess low dielectric constant and loss...
Low temperature preparation of CaCu3Ti4O12 ceramics with large permittivity is of practical interest for cofired multilayer ceramic capacitors. Although CaCu3Ti4O12 ceramics have been prepared at low temperatures as previously reported, they have rather low permittivity. This work demonstrates that CaCu3Ti4O12 ceramics can not only be prepared at low temperatures, but they also have large permittivity...
