Assignee: CORNING INCORPORATED
Field: Materials, metallurgy (Chemistry)
Classification: CPC C | IPC C

Claim 21:
22. The glass-based article of claim 1,
having a stress profile along the CT region, wherein stress is in tension, wherein the stress profile may be represented by Equation (1):

[Equation (1)]

Stress(x)=MaxT−(((CTn·(n+1))/0.5n)·|(x/t)−0.5|n)  (1)

wherein the stress (x) is the positive tension value at position x; MaxT is the maximum tension value; CTn is the tension value at n and is less than or equal to MaxT; both MaxT and CTn are positive values in MPa; the value x is a position along the thickness (t) in micrometers, with a range from 0 to t; MaxT is equivalent to maximum CT; and n is a parameter from 1.5 to 3.
