中文名称：白刚玉

英文名称：white fused alumina

定义：人造磨料的一种。三氧化二铝(Al2O3)含量在98％以上，并含有少量氧化铁、氧化硅等成分，呈白色。

产品简介：

白刚玉 以工业氧化铝粉为原料，于电弧中经2000度以上高温熔炼后冷却制成，经粉碎 整形，磁选去铁，筛分成多种粒度，其质地致密、硬度高，粒形成尖角状，适用于制造陶 瓷、树脂固结磨具以及研磨、抛光、喷砂、精密铸造等，还可用于制造高级耐火材料，代号“WA”于国际通用标准、国家标准一致，多数供出口，也有一定量供应国内用户。

产品粒度按国际标准以及各国标准生产，可按用户要求粒度进行加工。通用粒度号为 F4F220，其化学成份视粒度大小而不同。突出的特点是晶体尺寸小耐冲击，如果用自磨机 加工破碎，颗粒多为球状颗粒，表面干洁，易于结合剂结合。

白刚玉密度：

密度分为两种，一是白刚玉栈积密度，二是白刚玉真密度。

栈积密度为：1.531.99g/cm3，磨料的栈积密度与磨料的粒度，粒度组成，品种，颗粒形状等因素都有关，一般来说，粗粒度磨料比细粒度磨料栈积密度大，混合粒度磨料的栈积密度大于单一的粒度密度。

颗粒密度为：3.954.0g/cm3，近年巩义市满堂红磨料磨具厂的精铸 用刚玉真密度已达到4.1g/cm3，磨料的真密度是指单位体积（排除开气孔的体积）内所含磨料的质量。 　　

基本粒度为：4555 ，基本粒度是保证研磨效果的重要指标，在生产时应可以适当控制，但生产速度可能放缓。

Every abrasives factory brief introduction:

gongyi city every abrasives factory] is located in gongyi city, henan province, 15 km away from historic temples temple shaolin temple, main: corundum, brown corundum, white corundum, black corundum, bauxite aggregate, silicon carbide, polishing sand, rust removing sand, iron sand, corn cobs, walnut shell, castable, ramming material and so on. Specializing in the production of various types of brown corundum sand, 1. 2. 3 special sand particle size sand, wear-resisting flooring, metal polishing, sand, W63 - W5 series corundum powder, etc.; Gongyi city every abrasives factory is headquartered in gongyi city, has a complete and scientific quality management system and good faith, strength and product quality obtain industry acceptance. Welcome friends from all walks of life come to gongyi city every abrasives factory visit, guidance and business negotiation.

Chinese name: white corundum

English name: white fused product

Definition: a kind of artificial abrasives. 3 oxidation 2 aluminium (Al2O3) content over 98, and contains a small amount of ferric oxide, silicon oxide, such as composition, white.

Product synopsis:

White corundum using industrial alumina powder as raw materials, regularly above 2000 degrees high temperature smelting in electric arc made after cooling, the grinding plastic, magnetic separation to iron, screen is divided into a variety of particle size, dense texture, high hardness, particle formation Angle shape, is suitable for manufacturing ceramic porcelain, resin consolidation abrasive and grinding, polishing, sand blasting, precision casting, etc., can also be used for manufacturing high-grade refractory materials, codenamed "WA" international general standards, national standards, most for export, also has a certain supply of domestic users.

Product size according to the international standards and national standards production, processing granularity according to users requirement. Gm grain sizes for the F4 F220, its chemical composition depending on the size of the particle size. Outstanding characteristic is little impact resistance, crystal size, if use the broken mill processing, particles are spherical particles, the surface dry clean, easy to bond together.

White fused alumina density:

Density is divided into two kinds, one is white fused alumina bulk density, the second is Bai Gang YuZhen density.

Of packing density: 1.53 1.99 g/cm3, abrasive and abrasive granularity of packing density, particle size, varieties, and associated factors such as particle shape are, in general, coarse-grained abrasive abrasive than fine-grained bulk density is big, mixed abrasive granularity of packing density is greater than the single particle density.

Of grain density: 3.95 4.0 g/cm3, in recent years, gongyi every abrasives factory precision casting special just YuZhen has reached to 4.1 g/cm3 density, true density refers to the unit volume of abrasive (exclude open pore volume) contains the quality of the abrasive. Basic particle size as follows: 45 55, and basic particle size is the important measure to insure the effect of grinding, when production can be properly controlled, but production speed may slow.

White fused alumina properties:
