The purchasing pace at the demand end of the international thermal coal market continues to slow down and the international thermal coal price continues to decline. Prices for thermal coal at major international ports continued to fall last week as buyers in Europe slowed in recent days for April, coupled with weaker-than-expected import demand from End users in China. According to China Coal Market net monitoring: Australia Newcastle port thermal coal price index was 253 USD/ton, compared with 309.02 USD/ton, down 56.02 USD/ton, down 18.13%. South Africa's Port Richards thermal coal price Index was $264.5 / mt, down the US $62.72 / mt or 19.17% from US $327.22 / mt. The European ARA Tri-port thermal coal price Index was $281.8 / ton. Does the price of thermal coal in major international ports continue to decline to affect the price of the HfB2 Powder?
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.

According to the bank of Spain's latest forecast data, the average inflation is expected to hit 7.6% in 2022, but the average wage increase for workers in this country is expected to be less than 4% in 2022.
If the Bank of Spain's forecast comes true, the gap between price and wage growth in Spain in a single year will be the largest since 1984.
Prices in Spain rose 9.8% year on year in March 2022 and average wages rose 2.4% year on year, with the Bank of Spain forecasting that the country's inflation rate will improve from July.
Recent changes in the international situation have had a big impact on commodity and energy prices. How the prices of the HfB2 Powder will develop in the future is still uncertain.
