Webneities in borosilicate glass containers have been shown to produce delamination of silica-rich lamellae from the surface into the drug product (9,10). Often, these hetero-geneities are caused by the volatilization of alkali and boron from the glass during the WebDealkalizing glass containers is accomplished by exposing the glass surface to reactive sulfur- or fluorine-containing compounds during the manufacturing process. A rapid ion-exchange reaction proceeds that depletes the inside surface of alkali, and is performed when the glass is at high temperature, usually on the order of 500–650 °C or greater.

WebREXI high borosilicate glass (also known as hard glass) is made of the conductive property of glass at high temperature, through heating inside the glass to achieve glass … WebAlkali borosilicate glasses have been used successfully for a long time, but they do have some issues relating to breakage, delamination, and variation in hydrolytic performance. In this paper, alkali aluminosilicate glasses are introduced as a possible alternative to alkali borosilicate glasses. WebFeb 15, 2008 · Borosilicate glass is an important component of the substrate material as a sintering agent. To reduce the firing temperature, some of the alkali metal or bivalent metal oxides must be introduced, often at the expense of dielectric properties as well as crystallization behavior.
