摘要:
Various building materials constructed from different recycled components are provided. Such materials include boards, bricks, and the like, and exhibit differing levels of tensile strength, heat resistance, and other physical and chemical properties. The capability of introducing varied collected items, including paper, paperboard, clothing fibers, wood chips and strips, raffia bags, used engine oil, etc., and produce a resilient and dimensionally stable building material is presented herein. Replacement of timber and concrete is permitted with such a new material based upon renewable resources. The method of production and use of such materials is encompassed herein as well.

By controlling the heating speed and the pressure in carbonizing a wood powder, a macroporous carbon material is formed. Herein provided are the macroporous carbon material starting from a wood material, and a method for producing it.
摘要:
Ceramics are made of preceramic paper or board structures in a particular shape previously represented in a paper structure, in which the preceramic papers or boards have a content of ceramic fillers between 30 and 95 wt-%, with the ceramic fillers having a particle size
摘要:
A process form producing ceramic composites comprising metal carbides, which comprises the steps production of a porous carbon-containing intermediate body, infiltration of the intermediate body with the melt of a carbon-forming metal, reaction of at least part of the carbon of the intermediate body with the carbide-forming metal to form a metal carbide, with at least part of the carbide-formed metal being supplied via at least one wick made of porous carbon material having pore channels and the wick being produced by carbonization of wood materials or of essentially unidirectionally reinforced CFRP, such wicks and their use in the abovementioned process.
摘要:
A carbonaceous material, also referred to as a carbon alloy, and a process of making the carbonaceous material is provided. A particulate of partially pyrolyzed carbon (PPC) base is formed on heating a carbon-containing feed material and a nucleating agent in the form of a interactive filler is included. The nucleating agent is adhered together to the PPC particles by application of heat. The material is molded into a shape, voids in the material are collapsed and the resulting carbon alloy is cooled
摘要:
A friction material including two or more kinds of titanates and a ceramic fiber. The friction material includes no copper component. The two or more kinds of titanates may optionally include two or more kinds of alkali metal titanates, or the two or more kinds of titanates may optionally include an alkaline earth metal-alkali metal titanate and an alkali metal titanate.

摘要:
A ceramic filter comprising: (a) from about 75% to about 95% by weight of diatomaceous earth; (b) from about 10% to about 20% by weight of a flux; and (c) from about 0.03% to about 0.4% by weight of a metallic compound; the percentages by weight being percentages by weight of the ceramic filter.
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.
