JOURNAL OF MATERIALS SCIENCE40(2005)2101– 2103 LETTERS Pressureless sintering of silicon nitride/boron nitride laminate composites E. B. PICKENS, R. W. TRICE Purdue University, School of Materials Engineering, West Lafayette, Indiana 47907-2044, USA
Pyrolysis and Sintering processes are used to fill the ceramic matrix in between the fibers. The sintering process of ceramic composites doesn't require an oxygen free atmosphere, but tight temperature control and temperature uniformity inside the furnace for heating and cooling yield better results.
The choice of sintering additives is limited for nuclear application. Though hot pressing method is most suitable for the production of near net shape products, it was not preferred because of its low productivity and high cost. In the above perspective, experimental studies were performed on pressureless sintering of boron carbide.

Pressureless sintering of boron carbide powder (0.5 μm) at 2375 °C yielded a pellet of 93% ρth. Boron carbide (B 4 C) ceramic is an advanced material with a combination of excellent
Boron carbide, B4C, is an extremely hard ceramic material discovered in 1899. It is the third hardest materials known, after diamond and cubic boron nitride. The Mohs hardness of this boron carbide ceramic is about 9.49 and it was applied widely in industries as wearing resistant material, abrasive.
sintered boron carbide because of the proprietary nature of this material. One method of making the dense polycrystalline boron carbide is by hot pressing (including hot isostatic pressing)1. In some cases densification is conducted by hot pressing (1900-2200°C at 0.02-0.04 GPa for 15-45 min) in graphite dies under vacuum or argon atmosphere.

Vacuum Furnaces Ultra Clean and Reliable. Have the confidence to run parts in 10-7 torr pressure ranges up to 2000°C at the push of a single button. Like our hydrogen furnaces, Camco's vacuum furnaces are available in many sizes and models, all equipped with the same outstanding user-friendly control features.
Boron carbide (chemical formula approximately B 4 C) is an extremely hard boron–carbon ceramic and covalent material used in tank armor, bulletproof vests, engine sabotage powders, as well as numerous industrial applications.
Boron Carbide Machining & Grinding. Boron Carbide can be machined in green, biscuit, or fully dense states. While in the green or biscuit form it can be machined relatively easily into complex geometries. However, the sintering process that is required to fully densify the material causes the Boron Carbide body to shrink approximately 20%.
Mictrostructural and kinetic studies permit to distinguish three concentration ranges of boron with in which the trajectory of sintering and the effect of boron are significantly different. The first range is that of very low concentrations, not exceeding the solubility of boron in silicon carbide . The densification degree of the materials
Mar 30, 2013 · I use Chinese furnace now for over Six years. We have bought and sold now close to Twenty units and all are working just fine. No complaints. You buy what you want?? If you are sintering 1000 units a day, then go buy the furnace you posted? IF not, then it is a complete waste of $$ and electricity I think? heat = heat.
In the MIM process a large amount of out gassing of binders takes place, which affects the vacuum level and hence the interstitial element pick up in the titanium. In this paper the effect of gaseous material in vacuum is discussed and an alternate method of debinding and sintering in argon is proposed.
Mar 14, 2012 · Argon is a favorite gas used in many vacuum brazing shops, since it is an inert gas that will not react with any of the metals being heat-treated or brazed in those vacuum furnaces. Thus, dry argon (as measured by a dewpoint meter right at the furnace) is often used for partial-pressure brazing applications, or for rapid-cooling needs, or
