摘要:
The invention provides a method to transform large quantities of waste glass into useful ceramic products by a low-cost manufacturing process. The major steps of the method consist of dry preparation of glass powder, granulation with a non-aqueous organic binder system, dry pressing with adequate green strength, and firing at low temperatures. Water and clay are not required in the processing, which eliminates problems that were encountered in the past. Only one firing step is needed with a low peak firing temperature of about 750 °C. The method conserves energy and natural resources compared to clay-based traditional ceramic manufacturing. High-quality impervious ceramic products with only a small amount of porosity can be produced by the invention.

The invention relates to the production of decorative facing materials using a glass-pelletizer and refractory filler. The inventive method for a continuous production of decorative facing slabs consists in loading of basic materials into casting-moulds which are placed on an open heat-insulated palette, and in thermal treatment in a furnace at a temperature ranging from 900 DEG C to 950 DEG C. After the thermal treatment, the palette with the moulds is taken out and conditioned at an ambient temperature during 80-90 sec accompanied by cooling the surface of the slabs to a temperature ranging from 600 DEG C to 634 DEG C. Afterwards, the slabs are placed in a heat-insulated closed space having a thermal resistance of walls which makes it possible to cool the surface of the slab to a temperature ranging from 100 DEG C to 140 DEG C with an average cooling rate ranging from 0.016 to 0.020 degrees/sec.
摘要:
The present invention describes an extrusion process for manufacturing a titanium-containing silicate glass honeycomb structure (100), having a variety of shapes and sizes depending on its ultimate application. The titanium-containing glass honeycomb has a very low coefficient of thermal expansion (CTE) and the CTE can be varied by adjusting the titanium level to match the CTE of members that are bonded to the honeycomb. Furthermore, the inventive honeycomb structure is lightweight, yet able to advantageously used as a light-weight support for such objects as mirrors. Especially extraterrestrial environments where temperature extremes are present. These honeycombs can be used singularly or in aggregates to provide such support. Embodiments are described wherein the mass of the honeycomb is further reduced by removing select portions of the honeycomb without deleteriously impacting its ability for load bearing.
摘要:
A production method for a plasma display panel comprising the steps of forming on and filling in a partition-forming recessed board a paste layer with a constant thickness using a paste-like partition-forming material containing glass frits, placing the paste-like partition-forming material-filled partition-forming recessed board on a substrate and transferring the paste-like partition-forming material onto the substrate, and heating the paste-like partition-forming material to burn away organic components and at the same time sinter the glass frits, thereby forming a partition and a dielectric layer. A plasma display panel produced by this method has its partition wall and dielectric layer formed from the same, paste-like partition-forming material containing low-melting-point glass frits.
摘要:
A burner manifold apparatus (10) for delivering reactants to a combustion site of a chemical vapor deposition process includes fluid inlets (32a, 32b), fluid outlets (49), and a plurality of fluid passages (50) extending therebetween. The fluid passages (50) converge toward each other from the fluid inlets to the fluid outlets. One embodiment includes a manifold base (12), a pressure plate (14), and a manifold burner mount (16) for mounting thereto a micromachined burner (58). The fluid passages (50) internal to the manifold base are configured to distribute symmetrically the fluid to the manifold burner mount. The fluid is then channeled through fluid passages in the manifold burner mount. The fluid passages converge, yet remain fluidly isolated from each other, and the fluid passages create a linear array for producing linear streams of fluid. Alternatively, the burner manifold apparatus may include a plurality of manifold elements in a stacked arrangement. In this alternative embodiment, the manifold elements are configured to produce a linear array of fluid passages at the top of the stack, increasing the number of fluid passages at each level of the stack closer to the top. As yet a further alternative, the burner manifold may be produced by extruding a particulate composite through a die to produce a manifold having fluid passages therein. This extruded manifold generally has a tapered section to which a burner may be mounted.

A method of making a multiwell plate (10) involving joining a top plate (11) that has been extruded and has a plurality of open ended channels, with a bottom plate (13) that is substantially flat. The top plate (11) forms the sidewalls (14) of the wells (12) of the plate and the bottom plate (13) forms the bottoms (16) of the wells (12). The resulting plate (10), which conforms to the industry standard footprint, has a potential high density of wells, the volume of which may be controlled by the height of the plate.
摘要:
The invention relates to a method for producing very resistant, plate-shaped building and decorating materials similar to natural stone for trimming facades, walls and floors in interior and exterior areas. Said materials are produced from mixtures of broken glass, mineral components and fine-piece admixtures with a given composition. The mixture is thus mixed with a sintering auxiliary agent in the form of a solution of metal oxychlorides, metal alcoholates or tetrachlorides, preferably titanium tetrachlorides, and is placed inside a temperature resistant mold afterwards. The mixture is subjected to a common sintering process in said mold. Due to the added sintering auxiliary agents, the maximum sintering temperature is lowered and the quality of the surface is significantly improved.
