ABSTRACT:
A negative thermal expansion glass ceramic having a negative coefficient of thermal expansion, which is a sufficiently large absolute value in a temperature range of −40° C. to +160° C. and a method for producing the same are provided. The negative thermal expansion glass ceramic has a coefficient of thermal expansion of −25 to −100×10−7/° C. in the temperature range of −40° C. to +160° C., and comprises main crystalline phases which are one or more types selected from a group consisting of β-eucryptite solid solution (β-Li2O•Al2O3•2SiO2solid solution), β-eucryptite (β-Li2O•Al2O3•2SiO2), β-quartz solid solution (β-SiO2) solid solution), and β-quartz (β-SiO2), wherein a total amount of crystals of the main crystalline phases can be 70 to 100% in mass percent.
