Abstract: The β-eucryptite is one of the exotic matters in nature owing to its negative thermal expansion coefficient, and characterized by good thermal shock resistance, dielectrical property and infrared radiation. Eucryptite with negative thermal expansion coefficient was usually composed with other materials, then low thermal expansion or zero thermal expansion composite can be produced, whose volume stability of the materials enhanced and service life of materials was improved. So eucryptite was usually be used to produce low thermal expansion or negative thermal expansion ceramics and glass-ceramics, electrical equipment, electronic components, stuffing of device sealant, high precision components for aircraft, metal matrix composite, sensitive material for humidity sensor and solid electrolyte for lithium-ion batteries and so on. According to the investigated results of utilization of eucryptite in ceramics, metal, glass-ceramics and other applications, the progress of utilization of eucryptite material was systematically introduced in this paper.

Key words: eucryptite; negative thermal expansion coefficient; mineral; ceramics; glass-ceramics
