Oil futures tumbled more than $5 a barrel on news that the Biden administration is considering releasing about 1 million barrels a day from the U.S. Strategic Petroleum Reserve (SPR) for several months to cool surging crude prices.
Brent crude futures were down $4.71, or 4.2 percent, at $108.58 a barrel by 0035 GMT. U.S. West Texas Intermediate futures fell $5.45, or 5 percent, to $102.74 a barrel.
At an earlier time, gasoline prices had already reached record levels because of the Russia-Ukraine conflict.
The prices of other commodities like the HfB2 Powder are also expected to be volatile.
Introduction to Hafnium Diboride HfB2 Powder
Hafnium diboride or HfB2 is a gray-black metallic luster crystal. Its crystal structure belongs to the hexagonal system.
Physicochemical Properties of Hafnium Diboride HfB2 Powder
As an excellent high-temperature ceramic material, HfB2 has a high melting point (3380℃). It has high purity, small particle size, uniform distribution, large specific surface area, high surface activity, low loose density, high conductivity, and stable chemical properties. At room temperature, hafnium diboride reacts almost completely with all chemical reagents except HF.

Applications of Hafnium Diboride HfB2 Powder
Hafnium diboride is characterized by high hardness, high modulus, high thermal conductivity, and high electrical conductivity. Mainly used in high-temperature ceramics, high-speed aircraft nose cones and aviation, aerospace, and other fields. It is a potential candidate material for high-temperature ceramics and is often used as an ablative material in the high-temperature oxidation environment.
What is Ultra-High-Temperature Ceramics (UHTCs)?
Ultra-high temperature ceramics (UHTC) are a class of refractory with excellent stability at temperatures in excess of 2000 °C and are being investigated as possible materials for thermal protection systems (TPS), coatings for materials that withstand high temperatures, and materials for bulk materials heating elements.
Beginning in the early 1960s, the need for high-temperature materials from the emerging aerospace industry prompted the AIR Force Materials Laboratory to fund the development of a new material that could withstand the environments of proposed hypersonic aircraft such as the Boeing X-. Through a systematic study of the fire resistance of binary ceramics, they found that the early transition metals borides, carbides and nitrides had surprisingly high thermal conductivity, oxidation resistance, and reasonable mechanical strength. Among them, ZrB2 and HfB2 of the composites containing about 20% volume SiC have the best performance.
Broadly speaking, UHTC is a boride, carbide, nitride and oxide of early transition metals. Current efforts focus on heavy early transition metal borides, such as hafnium diboride (HfB2) and zirconium diboride (ZrB2). Other UHTC being investigated for TPS applications include hafnium nitride (HfN), zirconium nitride (ZrN), titanium carbide (TiC), titanium nitride (TiN), thorium dioxide (ThO2), Tantalum carbide (TaC) and related composites.
Diborides tend to have higher thermal conductivity but lower melting points than carbides and nitrides, which gives them good thermal shock resistance and makes them ideal for many high-temperature thermal applications.

Commodities such as crude oil, wheat, cotton, and nickel have rallied since Russia's "special military operations" began in late February. On the last trading day of this quarter, commodities were on track for their biggest gain since 1990. For this reason, it is expected that the price of the HfB2 Powder will continue to increase.
