How is Niobium Carbide NbC powder produced?
Russian crude oil shipments to Italian and Turkish ports rose to multi-week highs, suggesting that some southern European countries are quietly returning to the Russian oil market.
Specific figures show that Russian crude oil deliveries to Italian refineries rose to their highest level in seven weeks in the week to August 5, while shipments to Turkey reached the highest level in six weeks.
Separately, Spain received its first Urals this week since April, and Greece last week received its first shipments of crude from the Baltic Sea since February.
There are still four months to go before the EU sanctions on Rosneft come into effect. The recent increase in the flow of goods to several European countries has raised doubts about the implementation of the ban.
In addition to some southern European countries began to import Russian oil, Japan also reiterated that it will retain its stake in Russia's "Sakhalin 1" oil and gas project.
Last week, Russian President Putin signed an order banning personnel from "unfriendly" countries and regions, including Japan, from trading shares in Russian strategic projects, energy mining companies and some banks before the end of this year. It also mentioned the oil and gas project including "Sakhalin 1".
Because of the turbulent international situation, the supply and prices of many international bulk Niobium Carbide, NBC Powder Overview, Niobium Carbide Application, NBC Powder Price, Niobium Carbide Supplier are still very uncertain.
Overview of Niobium Carbide NBC Powder
Niobium carbide (NBC and Nb2C) is a very hard refractory ceramic material used commercially for cutting tool tips. It is usually processed by sintering and is a commonly used additive in cemented carbide as a grain growth inhibitor. The appearance is brown-gray metal powder with purple luster and strong corrosion resistance.
How is Niobium Carbide NbC powder produced?
Niobium pentoxide reduction method:
Niobium carbide can be obtained by heating niobium oxide in a vacuum at 1800°C and adding coke.
In industry, niobium carbide is usually prepared from niobium pentoxide and carbon black as raw materials: niobium pentoxide and carbon black are firstly mixed with carbide raw materials in proportion, and put into a graphite crucible. Heating hydrogen or vacuum to 1600～1800℃, carbonization for the first time, then adding carbon black, mixing it, heating to 1800～1900℃ under hydrogen or vacuum, secondary carbonization, this is niobium carbide.
Application of Niobium Carbide NBC Powder
Niobium carbide NBC powder can partially replace tantalum carbide and is widely used in refractory high temperature materials and cemented carbide additives
As a cemented carbide additive, niobium carbide is a solid solution component of ternary and quaternary carbides, such as WC-NBC-C ternary system.
Niobium carbide NBC powder can also be used to make purple artificial gemstones.

A spokesman for the Turkish presidential palace recently: the Black Sea Grain Export Joint Coordination Center may soon complete the final work of Ukraine's grain export route. The first ships carrying Ukrainian grain are expected to leave Ukraine's Black Sea port of Odessa on August 1 and re-export food to the international market. The grain ship will arrive in Istanbul, Turkey, as early as August 3, and then go to African countries.
Ukraine and Russia are both big grain exporters, among which Ukraine is known as the "granary of Europe". After the conflict between Russia and Ukraine broke out in February this year, grain exports of both countries were disrupted. The Ukrainian side accused the Russian army of blocking the Black Sea port on the Ukrainian side, resulting in more than 20 million tons of grain stranded in the port and unable to be transported by sea. The Russian side refutes this claim, accusing the Ukrainian side of laying a large number of mines in the waters near the port of the Black Sea, endangering navigation safety.
After coordination, Turkey, Russia, Ukraine and the United Nations Quartet signed an agreement in Istanbul on July 22 aimed at reopening blocked Black Sea transport routes. Ships carrying food can safely travel to and from three ports in southern Ukraine so that the stranded food of Ukraine can be transported to the international market. Russia and Ukraine agreed that neither side would attack ships carrying agricultural Niobium Carbide, NBC Powder Overview, Niobium Carbide Application, NBC Powder Price, Niobium Carbide Supplier are still very uncertain.
