This invention relates to a dense ceramics having ESD dissipative characteristics, tunable volume and surface resistivities in semi-insulative range (103-1011 Ohm-cm), substantially pore free, high flexural strength, light colors, for desired ESD dissipation characteristics, structural reliability, high vision recognition, low wear and particulate contamination to be used as ESD dissipating tools, fixtures, load bearing elements, work surfaces, containers in manufacturing and assembling electrostatically sensitive microelectronic, electromagnetic, electro-optic components, devices and systems.
摘要:
The purpose of the present invention is to provide a method for manufacturing a ceramic substrate hardly causing cracks and damages and the like attributed to pushing pressure and the like since the strength of the above-mentioned ceramic substrate is higher than that of a conventional one even in the case of manufacturing a large size ceramic substrate capable of placing a semiconductor wafer with a large diameter and the like. The present invention is to provide a method for manufacturing a ceramic substrate having a conductor formed on the surface thereof or internally thereof, including the steps of: firing a formed body containing a ceramic powder to produce a primary sintered body; and performing an annealing process to the primary sintered body at a temperature of 1400null C. to 1800null C., after the preceding step.

A ceramic material suitable for use in production of paving tiles, construction tiles, flooring in offices, flooring in machinery plants and so forth is obtained by a method comprising steps of mixing defatted bran derived from rice bran with a thermosetting resin before kneading, subjecting a kneaded mixture thus obtained to a primary firing in an inert gas at a temperature in a range of 700 to 1000null C., pulverizing the kneaded mixture after the primary firing into carbonized powders, kneading the carbonized powders with which ceramic powders, a solvent, and a binder as desired are mixed into a plastic workpiece (kneaded mass), pressure-forming the plastic workpiece at pressure in a range of 10 to 100 MPa, and subjecting a formed plastic workpiece thus obtained again to firing in an inert gas atmosphere at a temperature in a range of 100 to 1400null C.
摘要:
This invention relates to synthetic granite tiles made essentially from garnite sand and a process for the production of synthetic garnite tiles essentially from garnet sand which is a by-product of beach sand from rare earths extraction, said process comprising mixing beach sand garnet, feldspar and clay thoroughly; pressing the mixture using a press at a pressure in the range of 40-80 MPa to form tiles of desired shapes and sizes; drying the tiles so formed at a temperature of 100.degree.-120.degree. C.; firing the dried tiles at a temperature in the range of 1050.degree.-1250.degree. C. with a soaking for a period ranging from 1.5 to 2.5 hours, and polishing the resultant tiles.

The invention relates to a process for manufacturing brickworks mouldings by mixing a compound containing a granular clay-containing material with a lean material and, if required, other additives from which moulding compound green products are moulded, dried and burnt. This process permits a recycling of residual materials by using as clay-containing material a residual material consisting predominantly of clay minerals, especially a dry fraction, predominantly composed of annealed clay minerals, of an ash, preferably brown coal ash, and by producing the moulding compound by mixing the fraction with the lean material and other additives as well as water, where water is used in such a quantity as to produce an earth-moist moulding compound which is then pressed in portions on a press to form individual, inherently stable green products.
摘要:
A process for the preparation of whiteware ceramic articles employs an alkylenediamine, such as ethylenediamine, as an additive to increase the green strength of articles prepared by pressing. Optionally, the additive includes a latex such as a styrene butadiene latex in an amount effective to further improve the green strength of the articles prepared.

摘要:
A method of making disposable adobe dinnerware articles includes providing extracted clay with inclusions removed, preparing the clay to a predetermined consistency, and combining the clay with a filler to create an adobe mixture. The method can also include adding an additive, testing the humidity level of the adobe mixture and adjusting the humidity of the adobe mixture when the humidity is not within a predetermined humidity range, and preheating a mold. The method can also include adding the adobe mixture to the mold, and pressing the adobe mixture in the mold and heating the mold in a series of production stages to form a molded adobe tableware product.
