摘要:
Described is an inorganic fiber comprising silica dioxide, calcium oxide, and alkali oxide having a free energy of hydration greater than (more positive than) -5.00 kcal/mol, an enthalpy of formation less than (more than negative than) -210.0 kcal/mol, a dissolution rate in simulated extra cellular fluid greater than 750 (calculated as nanograms of fiber/per square centimeter of fiber surface area/per hour) having an average fiber diameter not greater than 4.5 micrometers. Also described is a method of manufacturing the fibers.
摘要:
A method of making a glass product comprising: providing a feedstock formed from at least one sedimentary rock comprising at least two minerals suitable for making the glass product; melting the feedstock to form a melt; and forming a glass product from the melt.
摘要:
A process for making a glass product with reduced greenhouse gas emission, comprising: providing a raw material composition comprising at least one silicon dioxide or silicon dioxide-containing compound and at least one pre-reacted compound, wherein the pre-reacted compound comprises an atom of an alkaline earth metal chemically bonded to an oxygen atom, and a silicon atom chemically bonded to the oxygen atom; melting the raw material composition to produce a molten material; and forming the molten material into a glass product.
摘要:
Provided are glass compositions uniquely applicable for the preparation of ultrafine fibers for filtration and separation applications. The glasses meet all physical and chemical criteria, including that for biodissolution rate.
摘要:
Novel boron-free glass compositions are described which are particularly suited for making fine diameter glass fibers for HEPA electronic clean-room filtration media using flame-attenuation or rotary glass processing.
摘要:
Provided is a range of glass compositions and glass fiber products made therefrom that show a unique combination of properties for both discontinuous fiber manufacturing and end use service. The glass compositions are particularly useful in high volume, high throughput, economical processes such as rotary spinning.
摘要:
The subject invention is directed to a method for producing a pre-reacted clinker used in the manufacture of E glass. The clinker is fed into an E glass furnace, and melts down into a finished E glass product at high efficiencies and short production times. The clinker allows glass to be produced at a lower cost as compared with known methods.

Provided are glass compositions uniquely applicable for the preparation of ultrafine fibers for filtration and separation applications. The glasses meet all physical and chemical criteria, including that for biodissolution rate. In particular, the glasses exhibit good moisture resistance in combination with excellent biosolubility, allowing for storage of products under humid conditions and degradation at a high rate in the body if inhaled.
