Patent ID: 8133829

Claim:
A frit comprising a low-melting point glass powder, a refractory filler powder and a heat absorbent powder, wherein the frit comprises substantially no lead and has a thermal expansion coefficient of at most 50×10 −7 /° C., and is processable at 500° C. or lower, wherein the low-melting point glass powder has a softening pour point of at least 30° C., and the refractory filler powder satisfies the following relationship: 1<S×ρ<10, wherein S is a specific surface area (m 2 /g), and ρ is density (g/cm 3 ), wherein the frit comprises from 45 to 65 vol % of the low-melting point glass powder, from 30 to 50 vol % of the refractory filler powder, and from 1 to 10 vol % of the heat absorbent powder.
