Abstract New degradable low-temperature co-fired ceramic (LTCC) composites consisting of AlN ceramic and low-melting composition B2O3-2SiO2 have been fabricated at sintering temperature of 850 °C. Boron exists in low-melting composition B2O3-2SiO2 in the form of [BO3] triangle, which can not form a uniform network structure with [SiO4] tetrahedron, this cause relatively lower chemical stability, further leading to the reaction of amorphous phase with water, therefor, the material can disintegrate when exposed to water, while Ag as electrode can be easily separated and recycled with gentle agitation and centrifugation. This has a certain significance in reducing soil pollution and water pollution caused by the landfill of LTCC products. and also in reducing the recycling costs. When AlN content is 40 wt%, samples sintered at 850 °C have thermal conductivity of 1.632 W/(m K), dielectric constant of 4.93, dielectric loss of 0.0064, and flexural strength of 60.26 MPa, results indicate that samples are potential for LTCC application.
