They’ve invented a “pre-ceramic monomer” made from silicon carbide powder, which prints just like any other polymer filament (in a $3,000 incredibly detailed stereolithic system, but still). But when exposed to UV light, the resin cures into a silicon carbide ceramic — which is to say an extremely durable, lightweight, non-conductive material.
The varied properties of Silicon Carbide (SiC) are helping to launch the material into many new appliions, particularly in the field of novel semiconductor devices. In this work, the cubic form of SiC is of interest as a basis for developing integrated optical components.

After heating at higher temperature (1500-1650 C) silicon carbide lines develop in x-ray diffraction, and fine crystalline regions of silicon carbide and graphite are found in TEM and electron diffraction. XPS shows that silicon-oxygen bonds in the glass are similar
This high-melting point transition metal was separated from niobium in 1802 by A. Ekeberg. When pure, tantalum can be drawn into a fine wire for use as a filament for evaporating metals. Due to its high melting point, ductility, and corrosion resistance, tantalum is often incorporated into a variety of metal alloys for use in chemical process equipment, capacitors and aircraft parts.
11/8/2016· Silicon is quite flexible and has a high melting point. Silicon Carbide (SiC)—to be more specific—is one of the most important elements known to man. It’s well known for its excellent thermo-mechanical properties and spectral absorbance.
Used in abrasives, polishing, grinding. It is widely applied in appliions calling for high endurance, such as automobile brakes, car clutches and ceramic plates in bulletproof vests. Electronic appliions of silicon carbide are the light-emitting diodes and sensors. It

The base of each “hair” is made out of uranium nitride fuel, which is coated with a soft buffer layer made out of porous carbon, followed by denser carbon, followed by silicon carbide — a material with a very high melting point.
However, boron carbide is very brittle and undergoes softening past the critical HEL point, unlike similar ceramics such as silicon carbide . This loss of strength limits the material’s performance in critical appliions. The sudden failure of boron carbide under
Silicon Dioxide has a high melting point - varying depending on what the particular structure is (remeer that the structure given is only one of three possible structures), but around 1700 C. Very strong silicon-oxygen covalent bonds have to be broken throughout the structure before melting occurs.
The deposition of the hydrogenated microcrystalline silicon carbide (μc-SiC:H) layers was carried out in a conventional rf (13.56 MHz) capacitive type plasma enhanced chemical vapour deposition (PECVD) system at a substrate temperature of 200 C from the mixture of silane, methane and argon at flow rates of 1.5 sccm, 1.5 sccm and 97 sccm respectively, with rf power density of 80 mW/cm 3 and

Titanium carbide (TiC) has a very high melting-point (3100 C), is extremely hard and strong, and is electrically conductive. Because of its electrical conductivity its Ti 2p -shape will be asymmetric, similar to that for Ti metal (the same -shape for the metal is used with good results in the TiC example given below).
