Hafnium Boride is a gray metal luster crystal with a melting factor of 3250℃ and a big electrical conductivity, chemical formulation HfB2. At room temperature, Hafnium Boride does no longer react with nearly all chemical reagents except HF. It is prepared via mixing and heating rhenium dioxide with boron carbide or boron oxide and carbon powder. HfB2 is used as a high-temperature resistant alloy.

Hafnium diboride has an excessive melting factor, excessive hardness, correct electrical conductivity, thermal conductivity, and precise neutron absorption overall performance. It has essential applications in ultrahigh temperature substances, superhard substances, electrode materials, and neutron absorption substances.

With the improvement of materials technology, the application fields of hafnium diboride ceramics and composite substances are getting more and greater. Obtaining low-fee, splendid scandium diboride powder is an important research path at home and overseas.

Hafnium Boride is hard to sinter, and as a way to enhance the overall sintering performance, the ultra-high-quality powder must be obtained. Although the nanometer powder has remarkable overall performance, it's far very costly, and it's miles tough to disperse at some stage in the processing of uncooked substances, and the method is tough. Therefore, the development of micron grade hafnium boride powder is receiving growing interest.

According to the Intel studies group, the probe of the storage hard disk sends statistics bit statistics to a ferroelectric movie with some nanometers location via sending instant electric pulses; the ferroelectric fabric is completely polarized through the encircling electric powered area to acquire information garage.

However, thinking about this extremely-excessive-pace information reading and writing pace and the large number of probes, the probe array of the reminiscence desires to be moved fast and frequently at the ferroelectric film. Such mechanical motion will motive the movie floor to put on. Will severely reduce the analyzing accuracy of the probe.

To resolve this hassle, the researchers coated the probe with a layer of hafnium diboride (HfB2), the hafnium diboride coating now not simplest reduces the damage velocity of the reminiscence, however, also can effectively ensure that the examine and write probe can flow within eight kilometers with wonderful high read and write accuracy.

With so many probes and tiny digital chips, Intel's new reminiscence could have a terrible garage capacity-it is able to keep greater than 1TB of facts in step with rectangular inch. However, Intel has now not introduced how lots the total reminiscence can be.

Intel's research on digital probe-primarily based business storage era has achieved a major step forward. The garage ability of this era will greatly exceed current mechanical tough drives and SSD solid kingdom drives.

"TheHafnium Boride ( HfB2 ) powder produced by using us is an excellent extremely-excessive temperature ceramic fabric," stated by means of Professor Luo, who's from Luoyang Tongrun Nanotechnology Co., Ltd, "Our hafnium boride is with high hardness, high modulus, excessive thermal conductivity, and excessive electrical conductivity, it's miles broadly utilized in wear-resistant coatings, refractory materials, cutting equipment and aerospace thermal safety structures."

"The hafnium diboride (HfB2) powder supplied with the aid of Luoyang Tongrun has entire specifications, excessive purity, and uniform particle length distribution, also we will customize the particle length for customers. it's miles an ideal preference on your research and improvement of extremely-high temperature ceramic substances and new warmness-resistant substances within the aerospace subject." Professor Luo summarize.
