黑刚玉简介

黑刚玉又名低铝刚玉，三氧化二铝(Al2O3)含量为70%～80%，是于电弧炉中，将铝矾土熔炼而制得的一种以α- Al2O3 和铁尖晶石为主矿相的灰黑色结晶体，其特点是Al2O3 含量较低，并有一定量的Fe2O3（10%左右）存在，因而具有硬度适中、韧性高、耐高温、热态性能温定硬度适中、其韧性较大耐磨棱角锋利、自锐性强、磨削是发热量少、抛光加工工件洁度高、切削力强、刚柔相济、耐磨性好、工效高的特点。

Black corundum and low aluminum corundum, 3 oxidation 2 aluminium (Al2O3) content is 70% ~ 70%, is in electric arc furnace, the bauxite made by melting a is given priority to with alpha Al2O3 and spinel mineral phase of the colored crystals, its characteristic is Al2O3 content is lower, and has a certain amount of Fe2O3 (10%), thus has moderate hardness, high toughness, high temperature resistant, thermal state performance steady moderate hardness, its toughness is larger wear-resisting, self-sharpening sex strong, sharp edges and corners are less calorific value, high pure degree of polishing machining, strong cutting force, the characteristics of flexibility, good wear resistance, high working efficiency.

黑刚玉含较多的氧化硅和氧化钛等杂质，呈黑色的一种刚玉。在磨料产品中，棕刚玉、白刚玉、黑刚玉同样都是以铝矾土为主要原料，加有铁屑在高温电弧炉中熔炼而成的，为什么黑刚玉的价格在其中是较低的呢，在市场上铝的价格比铁的价格每吨要高出好多，棕刚玉一级砂的三氧二化铝的含量在95%以上，而黑刚玉一级砂的三氧二化铝含量才达到85%，在此就可以看出黑刚玉的原因了。

Black corundum contains more silicon oxide and titanium oxide and other impurities, is a kind of black corundum. In abrasive products, corundum, white corundum, black corundum is same bauxite as main raw materials, with iron filings in the high temperature electric arc furnace smelting, and why the black corundum price is the lowest, in which the aluminum in the market price is the price of iron per ton higher lot, brown corundum sand level three oxygen two aluminum content is above 95%, and the black corundum sand level of three oxygen two aluminum content to reach 85%, in which can see the black corundum prices low.

黑刚玉特点

黑刚玉品硬度适中，韧性较大耐磨棱角锋利，自锐性强，抛光加工工件洁度高，其抛光性能大大高于国内外其他同类产品，广泛应用于餐具行业，电镀行业，金属表面处理行业，玻璃制品行业。

Black corundum products moderate hardness, toughness big wear-resisting sharp edges and corners, since the sharpness is strong, high pure degree of polishing machining, the polishing performance much higher than other similar products at home and abroad, is widely used in tableware industry, electroplating industry, metal surface treatment industry, glass industry.

黑刚玉的冶炼方式基本上和棕刚玉的冶炼生产方法一样。黑刚玉的生产方法是选用优质铝矾土、氧化铁等原材料，添加其它微量元素，经倾倒式电弧炉精心冶炼，保证了冶炼出的块状黑刚玉全为一级品，杂质少、品位高、质量稳定。为生产硬度适中、韧性好，使用性能优良稳定的段砂、粒度砂和微粉奠定了基础。

Black corundum smelting method basically and brown fused alumina smelting production methods. Black corundum production method is to choose the high quality bauxite, iron oxide, such as raw material, add other trace elements, by the dumping of electric arc furnace smelting carefully, to ensure the smelting of massive black corundum all for one, less impurity, high grade and stable quality. For producing moderate hardness and toughness, good use of high performance and stable period of sand, sand particle size, and micro powder laid a foundation.

黑刚玉用途

黑刚玉用于自由研磨，如制品电镀前的打磨工粗磨，主要用于不锈钢，金属制品，光学玻璃，竹木制品的抛光和喷砂，又是制造树脂砂轮，切割片，纱布的新颖磨料。本公司黑刚玉黑刚玉磨料基本粒集中，切削力强，韧性大，刚柔相济，耐磨性好，工效高。是磨削抛光、喷砂不锈钢制品的较理想产品。

Black corundum used for grinding freedom, like the beat of the products before electroplating grinder coarse grinding, it is mainly used for stainless steel, metal products, optical glass, bamboo and wood products polishing and sanding, making resin grinding wheel, cutting slices, gauze of new abrasive. The company black corundum, black corundum abrasive basic particle concentration, strong cutting force, tenacity is big, and flexibility, good abrasion resistance, high working efficiency. Grinding polishing, sandblasting of stainless steel products is the most ideal products.

黑刚玉段砂特别适合做高速公路、机场跑道、大桥路面等的耐磨防滑材料，适合做耐磨防滑地坪材料。各规格粒度砂粒度分布集中，公司内控指标高于国标，是优质的抛光研磨材料。具有硬度适中，韧性、自锐性、粘结性良好，经久耐用等特点。磨削时发热量小，不易划伤工件表面，不易引起工件表面变色，加工后工件表面光洁度高、色差极小。主要用于金属工件等研磨抛光，特别适合于不锈钢工件的研磨抛光，亦适用于光学玻璃、木材等材料的抛光，也大量用于制成树脂磨具，砂带等涂附磨具。温县明阳机械设备制造分厂长期供应优质棕刚玉、白刚玉、黑碳化硅、石英砂、核桃壳、玉米芯、黑刚玉、脱硫剂、地坪金刚砂、除锈砂、金刚砂、钢丸、铁砂、钢丝切丸等产品。

Black corundum sand is particularly suitable for high-speed road, airport runway, the wear-resisting of antiskid material such as bridge pavement, suitable for making wear non-slip floor material. Each specification size grain size distribution, the company internal control index is higher than the national standard, is the high quality of polishing abrasive materials. With moderate hardness, toughness, self-sharpening, good bonding, durability and other characteristics. When the grinding heat is small, not easy to scratch the surface, not easy to cause surface discoloration, processed workpiece surface roughness is high, the color difference. Is mainly used for metal artifacts such as grinding and polishing, especially suitable for grinding and polishing stainless steel workpieces, apply to polishing optics glass, wood and other materials, also used to make various resin abrasive, abrasive belt such as coated abrasive tool.County MingYang machinery manufacture factory long-term supply of high quality brown corundum, white corundum, black silicon carbide, quartz sand, walnut shell, corn cob, black corundum, desulfurizer, floor emery, rust removing sand, emery, steel shot, iron ore, steel cut wire shot, etc.

名称:金刚砂主题词或关键词:材料科学内容1891年，美国人阿切逊将粘土和焦炭混合后放在一个铁钵中，企图用电弧将碳转化为金刚石。但结果是，在电极附近发现了闪闪发光的六方形晶体，它与天然金刚石的立方八面体不同。阿切逊认为这可能是碳和粘土中的氧化铝反应而生成的新化合物。由于自然界中有一种氧化铝矿物称为刚玉，于是他把碳和刚玉两个英文单词连起来作为这一新化合物的名称，中国学者将其译成“金刚砂”。后来人们知道这种化合物是由粘土中的二氧化硅与碳在高温下反应生成的碳化硅。晶胞为面心立方结构，每个晶胞含有4个C原子4个Si原子。与金刚石结构类似。碳化硅硬度仅次于金刚石、碳化硼和立方氮化硼，在无机材料中排行第四。目前已能通过热压烧结法制得高致密度的碳化硅。它具有很高的强度及良好的抗氧化性能，在高温下不变形，可作为高温燃气轮机上的涡轮叶片，也可作耐磨的密封材料，还可作火箭尾喷管的喷嘴及轻质的防弹用品等金刚砂，SiC，学名碳化硅。纯的是无色晶体。密度3.06～3.20。硬度很大，大约是莫氏9度。一般的是无色粉状颗粒。磨碎以后，可以作研磨粉，可制擦光纸，又可制磨轮和砥石的摩擦表面。由砂和适量的碳放在电炉中加强热制得。天然金刚砂又名石榴子石，系硅酸盐类矿物。经过水力分选，机械加工，筛选分级等方法制成的研磨材料。生产使用历史悠久，古代我国就有使用金刚砂研磨水晶玻璃，各种玉石的史例。十九世纪四十年代又远销东洋。分粗目，中目，细目三大类。其中粗目为黑红色，中目为淡红色，细目为红白色，各种目数粒度均匀，颗粒形状均一，成棱叫角晶体，有锋利的边缘，磨削力高。供石材类工业研磨大理石及其它软质材料。玻璃类工业研磨玻璃毛边，电视机显像管，光学器械，镜片，棱镜，钟表用玻璃等。金属类工业喷砂，除锈，研磨。印刷工业研磨胶版，以及轻工业加工塑样，皮革，砂纸等用途。天然金刚砂的磨削力略低于电炉白刚玉，但其任性强，具有介壳状段口之特性，其优点是磨件的光洁度高，砂痕少而浅。磨面细而均匀，可提高产品质量，为本品的独特之处。天然金刚砂的研磨时间短，效益高，价格低廉，可弥补寿命短的不足。
