摘要:
Glass and glass ceramic compositions having a combination of lithium disilicate and β-spodumene crystalline phases along with methods of making the glass and glass ceramic compositions are described. The compositions are compatible with conventional rolling and float processes and have high mechanical strength and fracture resistance. Further, the compositions are able to be chemically tempered to even higher strength glass ceramics that are useful as large substrates in multiple applications.

What is achieved is an optical wavelength multiplexer/demultiplexer not necessarily requiring the function of adjusting the optical path. A value (ΔLmax−ΔLmin)/L obtained by dividing a difference between a maximum value ΔLmax and a minimum value ΔLmin of ΔL in a range of −40° C. to 80° C. by L is 8×10−6 or less where L represents a length of a crystallized glass (1) at 30° C. and ΔL represents a difference between a length (Lt) of the crystallized glass (1) at each of the temperatures and the length (L) thereof at 30° C.
