No Lead Low Temp Ceramic Frit

Ferro sealing glass pastes are formulated to seal with a variety of substrate materials at peak firing temperature as low as 430 c depending upon the application.

No lead low temp ceramic frit. Low firing crystallized frits were developed on the basis of pbo b 2 o 3 zno sio 2 system glasses. 4 282 035 also describes lead and cadmium free frits those frits exhibiting coefficients of thermal expansion 20 300 c between about 52 65 10 7 c maturing temperatures of. Frits to produce a well melted. Lead has been used in ceramics for thousands of years because it works so well that is leaded glazes melt at low temperatures have low thermal expansion dazzling colors and tolerance to variable firing.

Our ultra low temperature glass frit powders and pastes are used as an inorganic sealant and bonding material for amoled and oled panels and more. Frits are a modern development that have dramatically improved the safety with which the material can be handled. Low temperatures require the use of boron containing materials e g. The lead titanate is widely used as ceramic filler for the glass frits thermal expansion coefficient tec reduction.

Low temperature is in the cone 06 2 range about 1800f 2000f. Lead free low melting glass frit has a sufficient fluidity even at around 450 c 842 f. We specialize in ultra low temperature pb free glass frits that are rohs and reach compliant and designed to achieve maximum hermeticity. It is used for sealing and electrode binders.

Yek glass offers a large range of glass frit products. Glass frit for glass coating used to provide insulation and smoothness. I have not done low fire since 1974 raku in the 70 s and early 80 s and it was a great flux still have a bag of 6040 frit. This term generally refers to glazes that mature from cone 06 04 and are not functional.

Notwithstanding this leaded frits are. These materials provide low temperature hermetic sealing at 390 440 o c and transparent dielectric coverings at 550 o c. I turned in my 50 bag of white lead long ago to a hazmat day in our community along with old lead paint and my gallon of red lead paint like the golden. Low temperature lead free glass powders ferro offers a portfolio of standard and customized low temperature lead free glass powders formulated and processed with a wide range of properties for various microelectronics applications that meet the requirements of rohs compliant end products.

Its a low temp flux which is say low fire clay 1800f or raku temps. 4 282 035 also describes lead and cadmium free frits those frits exhibiting coefficients of thermal expansion 20 300 c between about 52 65x10 c maturing temperatures of. In ceramics glazes are loosely classified as low medium and high temperature.
