Nuclear Instruments and Methods in Physics Research Section B: Beam Interactions with Materials and Atoms, Vol. They are the characteristics that determine how it will react with other substances or change from one substance to another. The mechanical properties of sealants have been ex- amined in a series of studies. Parts are pressed and sintered by well developed methods to produce a ceramic with a unique set of outstanding properties. What are the Chemical Properties of Silicon? Some properties such as elongation, creep, cyclic flexing, tear strength, compression set, dielectric strength (at high voltage), thermal conductivity, fire resistance and in some cases tensile strength can be—at extreme temperatures—far superior to organic rubbers in general, although a few of these properties are still lower than for some specialty materials.
