Recently, the United States academy and Neibulasi add Carnegie scientist of school of university Lincoln cent cooperates, innovation gives the new form of a kind of carbon, mixed crystal and blame crystal two kinds of structures, be a kind " arrange what change in order without foreword " , can says " muddy Dun " crystal. This kind of material is adamant, dent can stay on diamond. This one discovery learns to wait for a domain to having wide application perspective in mechanical and mechanical, electronics, electrification. Carbolic element is discharged in the content in the universe the 4th, be next to hydrogen, nitrogen and oxygen, exist with a variety of forms: Xi of black lead of black lead, alveolate of diamond, monolayer, cylindrical accept rice canal, what still have basket figure is rich strap Xi (also cry " Ba Jiqiu " ) . These carbon some exist with crystal form, namely structure of carbolic atomic unit repeats ceaselessly, form the structure that has the law; Another kind a dispute crystal. In addition, the mixture form that the scientist thinks to have crystal and blame crystal possibly still exists, but never had observed before. This research by Carnegie the Wang Lin of the academy (transliteration) leader. They are in Ba Jiqiu (a kind of organic xylene is joined in C-60) (C8H10) dissolvent, high pressure brings to bear on after making its deliquescent, observation can produce what kind of change below different pressure. Below relatively low-pressure condition, c-60 still can maintain basket appearance, lift as pressure, basket the carbolic atom that the structure begins burst to become blame crystal forms a cluster. However, bunch of these blame crystal carbon still maintain in them original locally, form structure of a kind of crystal lattice. Researcher says for " carbon of orderly blame crystal forms a cluster " . The pressure range that forms this kind of structure is very narrow. Under 300 thousand atmosphere when, formation new structure can restore after removing pressure original bulbiform, after achieving 320 thousand atmosphere, new structure is stable, after removing pressure, also won't recover from an illness. Subsequently, the synchronous illuminant of national laboratory is opposite the advanced light source that researcher draws tribute state laboratory with A, Bulukehaiwen new material undertook detecting, test and verify its structure. They discovered the dent that extruding leaves on the diamond that the experiment uses, this shows the hardness of new material is close to diamond. If heat,get rid of the dissolvent in muddy Dun crystal, they can lose regular crystal lattice structure. Researcher explanation says, this shows solvent is crystal of Dun of this kind of muddy maintain its the key with transitional chemistry. Similar dissolvent still has a lot of kinds, be in accordingly theoretic, press through applying come to a kind construct as similar as this, but structure of lighter carbolic crystal lattice is a likelihood. Wang Lin says: "We created a kind of new-style material with carbon element, hardness can be compared with diamond photograph. Once form,this kind of material falls in extreme high pressure, can exist below normal condition, this means them to have extensive actual application value. This means them to have extensive actual application value.. CNC Milling CNC Machining
