Commodity prices are on track for their biggest rally in more than a century, while fixed-income assets have seen their longest run of outflows as the war in Ukraine adds to inflationary pressures in the global economy emerging from the coronavirus lockdown, according to Bank of America.
"Commodity prices this year are on track to record their biggest gains since 1915." the bank said in its weekly briefing. They cite many factors, such as pandemics, lockdown, civil strife, wars, excessive monetary and fiscal stimulus, and supply chain disruptions, that have led to "historically" high inflation.
By the same token, it said government bonds were heading for their worst year since 1949, and "negative-yielding bonds will quietly disappear" from the market as central banks embark on a monetary tightening cycle and raise interest rates to tame soaring inflation.
The prices of many commodities like the Cr3C2 Powder are expected to increase in the future.
Introduction to Chromium Carbide Cr3C2 Powder
Chromium carbide is an inorganic compound with the molecular formula Cr3C2 and the molecular weight is 180.01. It is gray powder with a rhombic system, A =2.821, B =5.52, C =11.46. The melting point is 1890℃ and the boiling point is 3800℃. The micro-Vickers hardness (load 50 g) is 2700kg/rnrn2, thermal expansion coefficient is 10.3×10-6/K.
It has properties of good wear resistance, corrosion resistance, and oxidation resistance in high-temperature environments (1000~1100℃). It belongs to a type of cermet. Because of its special high-temperature performance, it is widely used as a thermal spraying material for the metal surface protection process and as an additive in cemented carbide industry.
Physicochemical Properties of Chromium Carbide Cr3C2 Powder
Chromium carbide has many excellent properties, such as strong chemical stability, high-temperature hardness, thermal hardness, acid and alkali corrosion resistance, good wear resistance, and it has a high melting point. When chromium carbide is used as inhibitors, it can effectively control the grain growth of cemented carbide.
Moreover, chromium carbide is not only a good abrasion resistance of explosive bonding material additives, but also a high-quality cermet raw material, can also be used as a spraying powder, such as spraying powder at high temperature has good candle resistance, oxidation resistance, and wear resistance. It has been widely used in the metallurgical industry, electronic industry, high-temperature resistant coating, aerospace, and other fields.
In the field of cutting tools, chromium carbide usually plays an important role as a surface coating. In Fe-Cr-c alloy, chromium carbide is an important precipitated phase, which makes the material have excellent wear resistance.

Preparation Methods of Chromium Carbide Cr3C2 Powder
Metal chromium powder carbonization method:
325-mesh metal chromium powder was made by grinding carbon black at 13.5% ~ 64% (mass) ratio (more than the theoretical combined carbon content of 11.33%) with electrolytic chromium, and then used as raw material after dry mixing with a ball mill. Add 1% ~ 3% stearic acid as forming lubricant. Use pressure molding above 1 T/cm2. The pressurized molding powder into the graphite disc or crucible, with Taman furnace or induction heating furnace, in the hydrogen flow (hydrogen dew point at -35℃ or so), heated to 1500 ~ 1700℃, and keep 1h, so that chromium carbonization reaction, chromium carbide generation, after cooling, chromium carbide.
The reaction equation is: 3Cr + 2C → Cr3C2
Applications of Chromium Carbide Cr3C2 Powder
1. Can be used as carbide additives (such as tungsten carbide-based carbide grain refiner), so as to be used in mining, mechanical processing, and other aspects.
2. Can be used as welding material additives. The welding rod made of chromium carbide surfacing welding on the working surface of some mechanical equipment (such as coal mill, ball mill, jaw plate, etc.), can improve the service life of equipment several times more.
3. Used as thermal spraying materials used for metal surface protection process.
