Novel gas reaction coating process developed to protect fine powder against oxidation/corrosion during powder production, molding, and extended magnet service.--Industrial activity (Magnequench) Analysis of industry expert viewpoint confirmed next project direction: "System
Zn contained in the iron scrap is removed in the step of sintering to enable a light-weight iron scrap to be used in a large quantity in the blast furnace and, at the same time, to enhance the yield of sintered ore in the step of sintering.In the production of a sintered ore as a raw material for use in a blast furnace by using a Dweight-Lloyd
including vacuum sintering, hot-pressing, microwave sintering, and spark plasma sintering [20-23]. Among these methods, the carbothermal reduction of ilmenite is one of the most promising routes due to the low cost of raw materials. After carbothermal reduction, vacuum sintering is an effective densification tech-nique because of its simplicity
The volume of reaction formed SiC is greater than that of the original carbon (e.g., in the case of graphite, the expansion to SiC is 2.3 x). 1Thus, as shown in Figure 2, the final SiC:Si ratio of a RBSC ceramic can be controlled by the SiC to carbon ratio of the starting preform. Figure 1. Process Schematic for Reaction Bonded Silicon Carbide
So we prepared the silicon carbide green body with gel-casting method. Then some carbon materials were supplemented into the green body which will bring reaction-sintering with silicon in a vacuum furnace during 1500-1600°C, ultimately the reaction bonded silicon carbide was made. The diameter of SiC space mirror blank we have made is 680mm.
2019814To investigate the corrosion behavior of stainless steel parts produced by additive manufacturing, the Metallurgy section of the Department of Chemistry and Industrial Chemistry (DCCI) of the University of Genoa in collaboration with TAV VACUUM FURNACES, the Saiem Srl company of Cairo Montenotte (Savona) and the CNR-ICMATE of Padua started the
Refractory, any material that has an unusually high melting point and that maintains its structural properties at very high temperatures.Composed principally of ceramics, refractories are employed in great quantities in the metallurgical, glassmaking, and ceramics industries, where they are formed into a variety of shapes to line the interiors of furnaces, kilns, and other devices that process
The RED DEVIL™ furnace consumes little power--less than 2 kilowatts--and operates from a standard 20 amp wall outlet. A typical run at full temperature can be made at a utility cost of less than one US dollar. The RED DEVIL™ high temperature sintering furnace is an ideal choice for researchers interested in simple and efficient vacuum

Silicon Carbide Products for Industrial and Sintering Applications Sentro Tech offers products made from Sintered Alpha Silicon Carbide. Commonly used in sintered products for industrial application, alpha silicon carbide material makes very dense products by mixing very fine silicon carbide powder with non-oxide sintering additives at
Reaction bonded SiC is produced by permeating compacts, consisting of combinations of SiC and Carbon, with liquid Silicon. The Silicon reacts with the Carbon producing more SiC which joins the initial SiC particles. Sintered SiC is created from pure SiC powder with non-oxide sintering aids.
Chemical bonded magnesia chrome bricks are also called unburned magnesia chrome bricks. Unburned magnesia chrome bricks can realize sintering when they are used in industrial thermal kilns and furnaces and embody slag corrosion resistance and high temperature performance.
Here we present a new, cost-effective technique to obtain materials with high h-BN content and large dimensions, suitable for wide-scale industrial applications. Using h-BN and silicon powders as raw materials, reaction-bonded Si3N4/BN composites were obtained by complete nitriding of silicon.
19931012Ten (10) of the MOR bars were placed on reaction bonded silicon nitride (RBSN) supports, in an RBSN setter boat and covered with silicon nitride powder which contained yttria (Y 2 O 3). The setter boat was covered with reaction bonded silicon nitride plates to prevent reaction with the atmosphere of the sintering furnace.
the increase of sintering temperatures from 750C to 950˚ ˚C had no reaction between diamond and Ag-Cu-Ti system brazing for the components of sintered diamond/metal composites during the hot-pressing in vacuum. Figure 2 . indicates the variation of XRD patterns with the increase of pressure during the hot-pressing in vacuum for diamond/
The furnace vacuum rate decreased, and the temperature during the sintering became inhomogeneous, which result in batches of failure products. It makes us very headache. In the beginning of 2017, we finally decided to update our sintering equipment and invest a new large reaction sintering furnace.
