Synthesis Method and its Influence Factors of Hydrotalcite ...Hydrotalcitelike compounds are a class of anionic lays or layed double hydroxiods (LDHs) which consists of alkalescence, anionexchanges and memory effect. The synthetic methods of LDHs include coprecipitation, hydrothermal synthesis, mirowave radiation, ion exchange, solgel method, roasting reduction method, instant synthesis, molar ratio of raw materials, pH value,reaction ...
Polymers for 3D and Customized Additive ...Additive manufacturing (AM) alias 3D translates computeraided design (CAD) virtual 3D models into physical objects. By digital slicing of CAD, 3D scan, or tomography data, AM builds objects layer by layer without the need for molds or machining. AM enables decentralized fabrication of customized objects on demand by exploiting digital information storage and retrieval via the Internet.

Materials | Free FullText | Development of SiC/PVB ...Subsphaeroidal SiC/polymer composite granules with good flowability for additive manufacturing/3D of SiC were prepared by ball milling with surface modification using polyvinyl butyral (PVB). PVB adheres to the particle surface of SiC to form a crosslinked network structure and keeps them combined with each other into light aggregates.
A Novel Approach of Using Ground CNTs as the Carbon .by ball milling for 48 h and then condensed into cylindrical compacts (F 45 mm 35 mm) with green densities of ~65% 2% of theoretical density, as with 2009Al alloy powders. The combustion synthesis and vacuum hot pressing experiments were conducted in a selfmade vacuum furnace. The
Preparation of Single and FewLayer Graphene Sheets Using ...Single and fewlayer graphene sheets were fabricated by selective chemical reactions between Co film and SiC substrate. A rapid cooling process was employed. The number of layers and crystallinity of graphene sheets were controlled by process parameters. The formation mechanism of graphene was highly sensitive to carbon diffusion. Free carbon precipitated and then moved across the product ...

The Preparation and Properties of Clay Bonded Silicon ...In this paper, clay bonded silicon carbide was prepared through pressureless sintering process with silicon carbide dusting powder as raw materials and clay as sintering additive. The effects of the ballmilling method, sintering temperature and clay contents on the density, microstructure and mechanical properties of clay bonded silicon carbide refractory were studied.
A Database for Material Design of C/SiC CompositesContinuous carbon fiber reinforced silicon carbide composite material (C/SiC) is one of the most effective candidate materials for hot structures in aeronautic and aerospace applications. Its performances in the complicated service environments are widely concerned. A database, aiming at optimized design of C/SiC, was developed. The database collected original data on the fabrication ...
