Abstract (en)

[origin: EP0158187A2] A composite material having a low thermal expansivity obtained by combining 10 to 60 wt. % of a powdery Li2O-Al2O3-SiO2 mineral with 40 to 90 wt. % of one or more members selected from the group consisting of metals of Fe, Cu, Ni, Co, Mo, Ti. Cr, Al, Mn, Si, Zn, Ben and W and alloys of two or more of these metals to form the composite material containing the metal(s) having a reduced coefficient of thermal expansion.
