Silicon Carbide Micro Description
Silicon carbide Micro Powder crystallizes in a close-packed structure covalently bonded to each other. The atoms are arranged so that two primary coordination tetrahedral where four carbon and four silicon atoms are bonded to a central Si and C atoms are formed. Silicon carbide (SiC), also known as a semiconductor containing silicon and carbon.
It occurs in nature as the extremely rare mineral moissanite. Grains of silicon carbide can be bonded together by sintering to form very hard ceramics that are widely used in applications requiring high endurance, such as car brakes, car clutches, and ceramic plates in bulletproof vests.
Electronic applications of silicon carbide such as light-emitting diodes (LEDs) and detectors in early radios Large single crystals of silicon carbide can be grown by the Lely method and they can be cut into gems known as synthetic moissanite.
he material formed in the Acheson furnace varies in purity, according to its distance from the graphite resistor heat source. Colorless, pale yellow, and green crystals have the highest purity and are found closest to the resistor. The color changes to blue and black at a greater distance from the resistor and these darker crystals are less pure. Nitrogen and aluminum are common impurities, and they affect the electrical conductivity of SiC

Aluminum Diboride Powder Description
Aluminum boride Powder is an ionic compound, with a hexagonal crystal structure.  Aluminum boride at an absolute temperature slightly 40K (equivalent to -233 ℃) will be transformed into a superconductor. And its actual operating temperature is 20 ~ 30K. To reach this temperature, we can use liquid neon, liquid hydrogen, or closed-cycle refrigerator to finish cooling. Compared to the current industry using liquid helium to cool the niobium alloy (4K), these methods are simpler and more economical. Once it is doped with carbon or other impurities, magnesium diboride powder in a magnetic field, or there is a current passing, the ability to maintain the superconducting is as much as niobium alloys, or even better.

Chromium Carbide Cr3C2 Powder
Product Name: Chromium Carbide Cr3C2 Powder
| Product | Chromium Carbide |
| Colour | Gray Powder |
| Purity | ≥ 99.9% |
| Particle size | 1-10 µM (customizable) |
| Ingredient/MF | Cr3C2 |
| Product Code | NCZ-C-101/20 |
| CAS Number | 12012-35-0 |
Chromium Carbide Cr3C2 Powder APPLICATION FIELDS
Chromium Carbide Cr3C2 Powder is a ceramic compound that exists in several different chemical compositions: Cr3C2, Cr7C3, and Cr23C6. At standard conditions, it exists as a gray solid.
It is extremely hard and corrosion-resistant.
It is also a refractory compound, which means that it retains its strength at high temperatures as well.
These properties make use as an additive to metal alloys. When chromium carbide crystals are integrated into the surface of a metal it improves the wear resistance and corrosion resistance of the metal and maintains these properties at elevated temperatures.
Cr3C2 powder is mixed with solid nickel-chromium. This mixture is then heated to very high temperatures and sprayed onto the object being coated where it forms a protective layer. This layer is essentially its own metal matrix composite, consisting of hard ceramic Cr3C2 particles embedded in a nickel-chromium matrix.
Cr3C2 prevents large grains from forming in the composite, which results in a fine-grained structure of superior toughness.
Chromium Carbide Cr3C2 Application:
- Used as high temperature resistant and wear-resistant surface materials
- Used for welding and flux-cored wire
- Chromium carbide is useful in the surface treatment of metal components.
- Chromium carbide is used to coat the surface of another metal in a technique known as thermal spraying.
- Chromium carbide is used as an additive in cutting tools in order to improve toughness by preventing the growth of large grains.
Chromium Carbide Cr3C2 Properties:
There are three different crystal structures for chromium carbide corresponding to the three different chemical compositions. Cr23C6 has a cubic crystal structure and a Vickers hardness of 976 kg/mm2. Cr7C3 has a hexagonal crystal structure and a microhardness of 1336 kg/mm2.
Cr3C2 is the most durable of the three compositions and has an orthorhombic crystal structure with a microhardness of 2280 kg/mm2. For this reason, Cr3C2 is the primary form of chromium carbide used in surface treatment.

Niobium Boride Powder Related Information
Niobium boride powders having NbB, NbB2 and Nb3B4 phases in various amounts and single phase NbB powders were successfully synthesized by using powder metallurgy methods from related metal oxide raw materials in the presence of a strong reducing agent. Nb2O5, B2O3 and Mg powder blends were milled at room temperature
A high-energy ball mill for different time. Subsequently, an undesired MgO phase was removed from the milled powders by HCl leaching to constitute NbB–NbB2–Nb3B4 as final products, and they were subjected to an annealing process at 1500 °C for 4 h to observe probable boride transformation. Characterization was carried out by XRD, DSC, PSA, SEM/EDX, TEM, and VSM. The effects of milling time (up to 9 h) on the formation, microstructure, and thermal behavior of the final products were investigated.
The reduction reaction took place after milling stoichiometric powder blends for 2 h. Nano-sized NbB–NbB2–Nb3B4 powders in high purity were obtained in the absence of any secondary phase and any impurity via mechanochemistry by milling for 5 h and leaching with 4 mol/L HCl. After annealing, pure and nano-sized NbB–NbB2–Nb3B4 powders transformed into a single NbB phase without leaving behind NbB2 and Nb3B4 phases.
