白刚玉简介
白刚玉故名思议就是白色的刚玉,作为人造刚玉中的一种，颗粒外观呈现尖角形，洁白均匀纯度高。白刚玉具有硬度高、韧性稍低、防腐耐磨、纯度高、热稳定性好、颗粒洁白均匀、耐冲击的特点。白刚玉氧化铝可达到99%。质量有保证，因此更受广大用户的欢迎。白刚玉以氧化铝为制作原材料，经高温熔炼、粉碎、成型、分离杂质、加工为多种粒度的工艺制作而成，硬度比棕刚玉高一些，但是柔韧性不好。棕刚玉的硬度比白刚玉低些，市场价格远低于白刚玉，在人造刚玉中，白刚玉价格一直呈上升趋势，但是它的的使用范围较为广泛，且在使用过程中，性能非常稳定。
White corundum so incredible is white corundum, as one of the artificial corundum, particle appearance of pointed horn, white uniform high purity. White corundum with higher hardness, lower toughness slightly, anticorrosive wear-resisting, high purity, good thermal stability, white and uniform particles, the characteristics of impact resistance. White corundum, alumina can reach 99%. Quality assured, so more popular with the masses of users. White fused alumina in alumina production of raw materials, after high temperature melting, crushing, forming, separation of impurities, processing for the production of a variety of particle in the process, the hardness is higher than brown fused alumina, but flexibility is bad. Corundum hardness is lower than white corundum, the market price is far lower than the white corundum, in artificial corundum, white corundum price has been on the rise, but its scope is widely used, and in the process of use, performance is very stable.
白刚玉性能
1.硬度高，颗粒致密，单颗粒圆形度好。
2. 颜色纯白，无杂质，保证耐磨层或耐磨纸色泽与透明性。
3. 粒度分布均匀集中，单颗粒形一致，用较少量可达较大耐磨效果。
4. 它是精选自经两千多度高温熔炼而成的优质白刚玉为原料，精细制作而成，白刚玉其化学性能稳定与酸、碱不发生作用，热收缩性极小。
1. High hardness, particle density, good circular single particles.
2. The pure white color, without impurities, guarantee the wear-resisting layer or wear-resisting paper colour and lustre and transparency.
3. The particle size distribution uniform concentration, single particle shape, with the least amount of biggest wear-resisting effect.
4. It is selected commit suicide by hanging oneself more than two thousand degrees high temperature melting of high quality white corundum as raw material, made of fine, white corundum its stable chemical properties do not interact with acid, alkali, with low thermal shrinkage.
白刚玉的密度分析一般情况下可分两种，堆积密度和颗粒密度。白刚玉的堆积密度与磨料的大小、形状、品种等整体因素都有相关性。一般情况下粗粒白刚玉比细粒的密度大，因为粗粒堆积密度较大，细粒堆积密度较小。但是按照颗粒密度分析后，粗颗粒内部的密度是少于细粒内部密度的，颗粒密度是根据颗粒去除内部气体，计算出的颗粒密度，粗粒密度的内部空隙是比细粒内部的空隙要多。
白刚玉也可以作为耐火材料，若是其中含有杂质会影响它的耐火性能。耐火材料的杂质中有的是易熔物，有的本身具有很高的熔点，但同主成分共存时，却可产生易熔物。故杂质的存在往往对主成分起强的助熔作用。助熔作用虽有时有助于材料的液相烧结，但对材料抵抗高温作用却有严重危害。
The density of white corundum analysis in general can be pided into two kinds, bulk density and particle density. White fused alumina bulk density and abrasive the size, shape, and overall factors such as varieties have correlation. Usually a coarse white corundum is greater than the density of fine grained, because coarse grain bulk density is larger, less fine particle packing density. But after analysis according to the particle density, the inside of the coarse particle density is less than the fine grained internal density, particle density is according to the particle removal of internal gas, calculate the particle density, coarse grain density of the internal space is more than the inside of the fine particle gap.
White fused alumina also can be used as refractory material, if it contains impurities will affect its fireproof performance. Impurities in refractory have a plenty of fusible, some itself has a high melting point, but with the principal component coexistence, but can produce fusible. Therefore, the existence of impurities tend to principal component of strong fusion effect. Help fusion effect, though sometimes contribute to the liquid phase sintering material, but have serious harm effect on material resistant to high temperature.
白刚玉用途
1、可用在各式喷砂和研光(Lapping)作业；
2、玻璃或压克力艺品之雾化美感加工；
3、电视屏幕制程中喷砂；
4、硅晶元之切割；
5、齿模之清洁喷砂；
6、精密铸造用型砂；
白刚玉不止在耐火材料、研磨材料、表面抛光、喷涂材料的范围中使用，在水质过滤的行业中，效果也是非常好的。在底部铺设几层白刚玉颗粒，净化水质的程度可达到90%。
白刚玉用于耐火材料中一般用于做骨料和细粉，它的优点是耐火度高、耐磨、耐冲刷、耐侵蚀、体积密度大、氧化铝含量高，主要用于高铝系和氧化铝系。做制品时还有高的荷重软化温度和高温体积稳定性。白刚玉的杂质决定了产品在使用过程中的寿命。由于冶炼时杂质尚未完全去除，因此白刚玉中还含有六铝酸钙、钙斜长石、尖晶石、金红石等次晶相及玻璃相、铁合金和固溶体等。
1, available in various types of sand blasting, and research the light (Lapping) homework;
2, glass or acrylic crafts aesthetic feeling of atomization processing;
3, the television screen process in sand;
4, silicon wafer cutting;
5, the teeth cleaning sand;
6, precision casting sand;
White fused alumina than in refractory materials, grinding materials, surface polishing, spray coating materials used in the scope of, in the industry of water filter, the effect also is very good. In the bottom layers of white corundum particles, degree of purifying water quality can reach 90%.
White corundum used for refractory material in general for aggregate and fine powder, it has the advantage of high refractoriness, wear-resisting, scouring resistance, corrosion resistance, bulk density, high alumina content, it is mainly used for high aluminum and alumina. When making products and high refractoriness under load and high volume stability. White fused alumina impurities decided the product in the process of using life. Because has not been completely remove impurities when smelting, so white corundum also contains six calcium calcium aluminate, plagioclase, spinel, rutile grades: crystal phase and glass phase, ferroalloy and solid solution, etc.
