Improved sintering behavior and microwave dielectric properties of SnO2-based ceramics and their LTCC materials with ultrawide temperature stability

Enhanced flexural strength and microwave dielectric properties of Li2MgTi3O8-based low temperature co-fired ceramics

“…In addition, LTCC materials have the characteristics of simple composition, low raw material cost and convenient preparation process, which make them suitable for large-scale production. 1–3 In a previous study, LMT ceramics exhibited relatively excellent microwave dielectric properties when sintered at 1050 °C: ε r = 24.58, Q × f = 60 065 GHz, and τ f = −6.65 ppm °C −1 . 4 However, their high sintering temperature and poor flexural strength (99.534 MPa) make them impossible to be used in LTCC ceramic substrate devices.…”
