Abstract

Official abstract text for this publication.

Disclosed herein are glasses that are capable of forming nepheline crystal phases when exposed to light, photoformable glass-ceramics comprising at least one nepheline crystal phase, products containing such glasses and glass ceramics, and methods for making the same.

First claim

Opening claim text (preview).

What is claimed is: 1. A glass ceramic composition comprising about: wt % Component 38-52 SiO 2 25-35 Al 2 O 3 10-25 Na 2 O  0-15 K 2 O >0-10 Halogen  >0-0.5 CeO 2  >0-0.5 Sb 2 O 3  >0-0.5 Ag >0-2  SnO wherein the glass ceramic comprises at least one nepheline phase. 2. The glass ceramic composition of claim 1 , wherein the composition comprises about: wt % Component 40-50 SiO 2 27-32 Al 2 O 3 15-25 Na 2 O >0-10 K 2 O >0-6  F −  >0-0.2 CeO 2  >0-0.3 Sb 2 O 3  >0-0.3 Ag 0-2 Br − or Cl − or combinations thereof  >0-1.0 SnO. 3. The glass ceramic composition of claim 2 , wherein the composition comprises about: wt % Component 40-50  SiO 2 25-30  Al 2 O 3 15-20  Na 2 O >0-10  K 2 O 2-5  F − >0-0.2 CeO 2 >0-0.3 Sb 2 O3 >0-0.3 Ag  0-0.5 Br − or Cl − or combinations thereof >0-0.8 SnO. 4. The glass ceramic composition of claim 1 , wherein the composition further comprises at least one lithium aluminosilicate phase or phosphate phase. 5. The glass ceramic composition of claim 1 , wherein the composition is thermally or chemically strengthened. 6. The glass ceramic composition of claim 5 , wherein the composition is chemically strengthened by ion exchange. 7. A glass-glass ceramic hybrid composition comprising: a) a glass phase having a composition comprising about: wt % Component 38-52 SiO 2 25-35 Al 2 O 3 10-25 Na 2 O  0-15 K 2 O >0-10 Halogen  >0-0.5 CeO 2  >0-0.5 Sb 2 O 3  >0-0.5 Ag >0-2  SnO and b) a glass ceramic phase having a composition comprising about: wt % Component 38-52 SiO 2 25-35 Al 2 O 3 10-25 Na 2 O  0-15 K 2 O >0-10 Halogen  >0-0.5 CeO 2  >0-0.5 Sb 2 O 3  >0-0.5 Ag >0-2  SnO wherein the glass ceramic comprises at least one nepheline phase. 8. The glass-glass ceramic hybrid composition of claim 7 , wherein the glass and glass ceramic phases each comprise about: wt % Component 40-50
