ceramics.pptmanjulikatyagi

听

Ceramics are inorganic, non-metallic materials formed from chemical and biochemical stable substances. Dental ceramics contain a glassy matrix reinforced by crystalline structures such as leucite, alumina, and silica. Dental porcelains are composed of feldspar, silica, and kaolin, which are blended and fired to form the ceramic. Metal-ceramic restorations consist of a metal coping covered with opaque, dentin, and enamel porcelain layers that are bonded to the metal through mechanical interlocking and chemical bonding between metal oxide layers and the ceramic.

Soldering and welding.pptxmanjulikatyagi

听

Soldering and welding are processes to join metal components. Soldering involves melting a filler metal below the melting points of the components being joined.
