Glass and metal melded vacuum-tight

New sealing glass with high thermal expansion

Our new glass type 0834 serves with its high thermal expansion of 9,9 ∙ 10^-6/K^-1 as well as its T_k100 of  265 ∙ 10⁸ Ω cm iideal requirements for the sealing of many steels, especially of ferritic steels (1.4762, 1,4820 und AISI446), which need a high thermal expansion coefficient. The glass has a wide temperature range of viscosities and can thereby be processed very well.
