    Abstract: The invention is directed to a glass composition that can be used to make glass frits suitable for use in the manufacturing of microreactors. The glass compositions, after final sintering to produce a finished microreactor, have a surface crystalline layer of 30 mum or less, or are completely amorphous throughout. Generally, the borosilicate glasses of the invention have a composition Of B2O3 = 12-22 mol %; SiO2 = 68-80 mol % and additional components selected from the group consisting of either (a) Al2O3 = 3-8 mol % and Li2O = 1-8 mol %, or (b) K2O = 0-2 mol % and Na2O = 0-2-ol %, except that both K2O and Na2O cannot both equal zero at the same time. One borosilicate glass has a composition, in mole percent (mol%) of B2O3 = 18-22 mol %, SiO2 = 75-80 mol %, K2O = 0-2 mol %, and Na2O = 0-2 mol %, except that both K2O and Na2O cannot both equal zero at the same time.

    Abstract translation: 本发明涉及可用于制备适用于制造微反应器的玻璃料的玻璃组合物。 玻璃组合物在最终烧结以生产成品微反应器之后具有30μm或更小的表面结晶层,或者完全是无定形的。 通常,本发明的硼硅酸盐玻璃的组成为B 2 O 3 = 12〜22摩尔% SiO 2 = 68-80摩尔%,另外的组分选自(a)Al 2 O 3 = 3-8摩尔%和Li 2 O = 1-8摩尔%,或(b)K 2 O = 0-2摩尔%,Na 2 O = 0-2-ol%,不同之处在于K2O和Na2O两者同时不能同时为零。 一种硼硅酸盐玻璃具有B 2 O 3 = 18-22摩尔%,SiO 2 = 75-80摩尔%,K 2 O = 0-2摩尔%,Na 2 O = 0-2摩尔%的摩尔%(摩尔%)的组成, K2O和Na2O都不能同时为零。
