Please contact customerservices lexology. The U. CVD law imposes special tariffs to counteract imports that are sold in the United States with the benefit of foreign government subsidies. Quartz surface products consist of slabs and other surfaces created from a mixture of materials that includes predominately silica e.

The incorporation of other materials including, but not limited to, pigments, cement, or other additives does not remove the merchandise from the scope of the investigation. However, the scope of the investigation only includes products where the silica content is greater than any other single material, by actual weight. Quartz surface products are typically sold as rectangular slabs with a total surface area of approximately 45 to 60 square feet and a nominal thickness of one, two, or three centimeters.

However, the scope of this investigation includes surface products of all other sizes, thicknesses, and shapes. In addition to slabs, the scope of this investigation includes, but is not limited to, other surfaces such as countertops, backsplashes, vanity tops, bar tops, work tops, tabletops, flooring, wall facing, shower surrounds, fireplace surrounds, mantels, and tiles.

Certain quartz surface products are covered by the investigation whether polished or unpolished, cut or uncut, fabricated or not fabricated, cured or uncured, edged or not edged, finished or unfinished, thermoformed or not thermoformed, packaged or unpackaged, and regardless of the type of surface finish. In addition, quartz surface products are covered by the investigation whether or not they are imported attached to, or in conjunction with, non-subject merchandise such as sinks, sink bowls, vanities, cabinets, and furniture.

If quartz surface products are imported attached to, or in conjunction with, such non-subject merchandise, only the quartz surface product is covered by the scope. Subject merchandise includes material matching the above description that has been finished, packaged, or otherwise fabricated in a third country, including by cutting, polishing, curing, edging, thermoforming, attaching to, or packaging with another product, or any other finishing, packaging, or fabrication that would not otherwise remove the merchandise from the scope of the investigation if performed in the country of manufacture of the quartz surface products.

The scope of the investigation does not cover quarried stone surface products such as granite, marble, soapstone, or quartzite. Specifically excluded from the scope of the investigations are crushed glass surface products. Subject merchandise may also enter under subheadings Customs purposes only. The written description of the scope is dispositive. If you would like to learn how Lexology can drive your content marketing strategy forward, please email enquiries lexology.

The manufacture of sintered glasses and glass-ceramics, glass matrix composites, and glass-bounded ceramics or pastes is often affected by gas bubble formation. Against this background, we studied sintering and foaming of barium silicate glass powders used as SOFC sealants using different powder milling procedures.

CROSS-REFERENCE TO RELATED APPLICATIONS

The effect of silica filler in the form of glass beads on polyethylene composite properties has been studied. Conditions for obtaining polyethylene-based composites in the extrusion process were developed. Two types of such composites were prepared: non-oriented and oriented in the uniaxial stretching process in a ratio of The morphology, microstructure including crystallinity degree , mechanical resistance, and thermal stability of the obtained composites containing 2. The innovative materials with the designed tailored utility properties determine the development of modern technologies, for instance, piezopolymers, can find many practical applications such as sensors, actuators, or transducers, in medicine, electronics, forensic, military, and space industries [ 1 , 2 , 3 ]. The piezomaterials, named also piezo-electrets, are characterized by the specific internal structure allowing for polarization and accumulation of electric charges, which can be transformed into mechanical forces and vice versa.

This is a continuation of application Ser. The present invention relates to a method for producing a glass preform for use in the fabrication of an optical fiber. More particularly, the invention is concerned with a method for producing a quartz glass preform with fluorine added thereto. A glass preform for use in the fabrication of an optical fiber comprises a core and a cladding surrounding the core. The core must have a higher refractive index than the cladding so as to allow easy propagation of light therethrough. In order to increase the refractive index of the core higher than that of silica, additives such as TiO 2 , GeO 2 and Al 2 O 3 are usually added to the core material. In a usual optical fiber, pure quartz glass is often used to form the cladding. Referring to FIGS. In these figures, the regions A and B indicate the core and cladding, respectively. The difference in refractive index between the core and cladding is usually indicated in terms of a relative refractive index difference in percent.

US3830686A - Photomasks and method of fabrication thereof - Google Patents

This non-provisional application claims priority under 35 U. This invention relates to a storage container for containing microelectronic material, and specifically a synthetic quartz glass substrate for use as photomask in the advanced microelectronic technology. The progress of microelectronic devices toward higher integration has created an increasing demand for the photolithography capable of forming a pattern with reduced feature size. At an initial stage of photolithography, a coating is often deposited on a synthetic quartz glass substrate.

By the combination of a three-axis system to move the glass sample and a fast 3D system to move the laser focus, the SLE process is now suitable to produce more complex structures in a shorter time. Here we present investigations which enabled the new possibilities.

Lehrer [ Aug. Lehrer, Seena Ave. Greiner [5 7] ABSTRACT Photomasks and method of fabrication thereof, whereby a thin layer of germanium is deposited to a substrate which may be then etched in a pattern to provide a photomask or information storage device. In the fabrication method, a substrate is carried by belt through a first inert gas curtain into a furnace containing a mixture of suitable gases for causing the deposition of germanium onto the heated substrate, and there outward through a second inert gas curtain into a cooling region. The use of a germanium film for a mask blank results in a mask which is reasonably transparent to visible light but substantially opaque to ultravoilet light, and which may be deposited on to and removed from various substrates including glass using etchants which do not attack the substrate material. Field of the Invention This invention relates to the field of photomasks and information storage devices. Prior Art In the prior art, negatives e. Subsequent exposure and development of the photoresist exposes areas of the chromium which can be etched away by a suitable etchant. After etching and removing the photoresist, a chromium image is left on the glass plate.
