摘要： A method of forming low-k material is provided. The method includes providing a plurality of core-shell particles. The core of the core-shell particles has a first ceramic with a low melting point. The shell of the core-shell particles has a second ceramic with a low melting point and a low dielectric constant. The core-shell particles are sintered and molded to form a low-k material. The shell of the core-shell particles is connected to form a network structure of a microcrystal phase.

摘要： A method of forming a ceramic material includes providing a mixture of solid powder, which includes precursors of crystalline aluminum silicate, amorphous fluxing agent, and amorphous modifier. The method also sinters the mixture of solid powder at 1600° C. to 1800° C. to form the ceramic material, which includes 100 parts by weight of the crystalline aluminum silicate having a chemical formula of AlSixO1.5+2x, wherein x is 0.21 to 0.35, 10 to 15 parts by weight of the amorphous fluxing agent, and 5 to 10 parts by weight of the amorphous modifier.

摘要： A ceramic material includes zirconia toughened alumina (ZTA) doped with scandium (Sc) ions. ZTA can be further doped with other metal ions, and the other metal ions include cobalt (Co) ions, chromium (Cr) ions, zinc (Zn) ions, titanium (Ti) ions, manganese (Mn) ions, nickel (Ni) ions, or a combination thereof. The ceramic material can be used as a ceramic object, such as a wire bonding capillary, a heat dissipation plate, a denture tooth, orthopedic implants, direct bonded copper, or a high-temperature co-fired ceramic.
