Tantalum Carbide Powder

Tantalum carbide (TaC) is an extremely hard (Mohs hardess 9-10) refractory ceramic material. The hardness is only exceeded by diamond. It is a heavy, brown powder usually processed by sintering, and an important cermet material.

They are extremely hard , brittle,refractory ceramic  materials with metallic electrical conductivity.

Tantalum carbides (TaC) is used to increase the performance of hard metal cutting tools that are very important due to their use in growth markets such as the automobile and aerospace industries. It is sometimes used as a fine-crystalline additive to tungsten carbide alloys.

Zirconium Carbide powder

It has the appearance of a gray metallic powder with cubic crystal structure. It is highly corrosion resistant. Like most carbides of refractory metals, zirconium carbide is sub-stoichiometric, i.e., it contains carbon vacancies. At carbon contents higher than approximately ZrC0.98 the material contains free carbon.[5] ZrC is stable for a carbon-to-metal ratio ranging from 0.65 to 0.98.

Hafnium-free zirconium carbide and niobium carbide can be used as refractory coatings in nuclear reactors. Because of a low neutron absorption cross-section and weak damage sensitivity under irradiation, it finds use as the coating of uranium dioxide and thorium dioxide particles of nuclear fuel. The coating is usually deposited by thermal chemical vapor deposition in a fluidized bed reactor.

Chromium Powder  is the hardest metal element in the periodic table and the only element that exhibits antiferromagnetic ordering at room temperature, above which it transforms  into a paramagnetic solid. Chromium does not oxidize in air, even in extreme moisture.

The most common source of chromium is chromite ore (FeCr2O4). Due to its various colorful compounds, Chromium was named after the Greek word ‘chroma’ meaning color. It is also employed to give glass an emerald green color .

Chromium Powder  is used as a hardener in steel, for the manufacture of stainless steel and many useful alloys. Also can be Pigments, dyes, corrosion/oxidation resistant plating and coating refractory products, superalloys , stainless steel, electronics, supptering source,magnetic storing materials, betteries, catalysts, welding alloys, and thin film for electronics.

In combustion equipment, chromium is used as a wear-resistant coating to increase the service life of specific components.

As a component in high-temperature fuel cells, our chromium also performs brilliantly. Alongside these applications, our chromium is also used as a brilliant decorative coating for operating elements on appliances or for jewellery..
