【白刚玉简介】
白刚玉是离子型晶体，结构稳定，因常含微量Ti、V、Fe、Cr等杂质，而呈现不同的颜色，白刚玉因为纯度高所以呈白色。白刚玉只所以能成为很好的耐磨材料得益于他的纯度高、耐酸碱腐蚀好，耐磨效率高、自锐性好、磨削能力强、耐高温热稳定性好，磨削时易切入工件，发热量较小的物理和化学性质。经加工的白刚玉细粉分为0-1mm，1- 3mm，3-5mm，5-8mm，8-12mm几种型号，主要用于耐火材料，砂轮铸造。
White corundum is ionic crystals, the structure is stable, because often contain trace impurities such as Ti, Fe, Cr, V, and presents the different color, white corundum because of the high purity so white. White corundum only so can become very good wear resistant material benefit from his high purity, good acid and alkali corrosion resistance, wear resistance of high efficiency, good self-sharpening, good thermal stability, strong grinding ability, high temperature resistant, easy to cut into the workpiece when grinding, physical and chemical properties of calorific value is small. Processed white corundum powder into 0 to 1 mm, 1-3 mm, 3-5 mm, 5-8 mm, 8-12 mm several models, it is mainly used for refractory materials, grinding wheel casting.

【白刚玉特性】
明悦白刚玉是以优质铝氧化粉为原料，经电熔提炼结晶而成，纯度高、自锐性好、耐酸碱腐蚀、耐高温、热态性能稳定。白刚玉硬度略高于棕刚玉，韧性稍低，纯度高、自锐性好、磨削能力强、发热量小、效率高、耐酸碱腐蚀、耐高温热稳定性好。用白刚玉粒度砂制成磨具，适用于磨削高碳钢、高速钢及不锈钢等细粒度磨料，白刚玉还可以用于精密铸造和高级耐火材料。
明悦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，它的的使用范围较为广泛，且在使用过程中，性能非常稳定。明悦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。
White corundum is of high quality aluminum oxide powder as raw material, the crystal in a fused, high purity, good self-sharpening, naisuanjian corrosion, high temperature resistant, thermal state performance is stable. Is slightly higher than that of brown fused alumina, white fused alumina hardness toughness slightly low, purity, good self-sharpening, high grinding ability, low calorific value, high efficiency, good thermal stability, acid and alkali corrosion resistance, high temperature resistant. Made with white corundum sand particle size abrasive, suitable for grinding high carbon steel, high speed steel and stainless steel, such as granular abrasive, white corundum can also be used for precision casting and high-grade refractory materials.
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, the use of its range is relatively wide, and in the process of use, performance is very stable. MingYue white corundum, alumina can reach 99%. Quality assured, so more popular with the masses of users.
【白刚玉和棕刚玉区别】
刚玉因为所含的色素离子不同而呈现不同的颜色，区别主要体现在哪些地方呢？
白刚玉和棕刚玉在原料上的区别：白刚玉以优质氧化铝粉为原料，经电容提炼结晶而成；棕刚玉以铝矾土、铁屑和无烟煤为主要原料，在电炉壶内冶炼而成。
白刚玉和棕刚玉在用途上的区别：白刚玉主要用于陶瓷制造、树脂磨具以及喷砂、抛光、研磨、精密铸造和高级耐火材料；棕刚玉主要用于：砂轮、喷砂、自由研磨、涂附磨具、功能性填料、过滤介质、耐火材料。
白刚玉和棕刚玉在密度上的区别：一般磨料密度有堆积密度和真密度两种，堆积密度是磨料填满容器后的密度，而真密度是真空状态下测得的密度。白刚玉的堆积密度：1.53~1.99g/cm3，白刚玉的真密度：3.95~4.0g/cm3。
Corundum because contains pigment ion and present different color, different difference mainly reflects in what place?
White corundum and the difference of brown fused alumina in the materials: white corundum with high quality alumina powder as raw material, the capacitance extraction crystallization; Brown fused alumina bauxite, iron filings and anthracite as main raw material, the smelting electric furnace in POTS.
White corundum and corundum difference in the use of: white fused alumina is mainly used in ceramics, resin abrasive and sand blasting, polishing, grinding, precision casting and high-grade refractory materials; Brown fused alumina is mainly used for grinding, sandblasting, free grinding, coated abrasive, functional fillers, filter medium, refractory materials.
White corundum and brown fused alumina on the density difference: general abrasive density has two kinds of packing density and true density, bulk density is the density of abrasive after fill the container, and the true density is measured the density of the vacuum condition. White fused alumina bulk density: 1.53 ~ 1.99 g/cm3, white corundum true density: 3.95 ~ 4.0 g/cm3.
