中文名稱：白剛玉
英文名稱：white fused alumina
定義：人造磨料的一種。三氧化二鋁(Al2O3)含量在98％以上，并含有少量氧化鐵、氧化硅等成分，呈白色。
 
白剛玉產品簡介：
 
白剛玉 以工業氧化鋁粉為原料，于電弧中經2000度以上高溫熔煉后冷卻制成，經粉碎 整形，磁選去鐵，篩分成多種粒度，其質地致密、硬度高，粒形成尖角狀，適用于制造陶 瓷、樹脂固結磨具以及研磨、拋光、噴砂、精密鑄造等，還可用于制造高級耐火材料，代號“WA”于國際通用標準、國家標準一致，多數供出口，也有一定量供應國內用戶。
 
白剛玉產品粒度按國際標準以及各國標準生產，可按用戶要求粒度進行加工。通用粒度號為 F4~F220，其化學成份視粒度大小而不同。突出的特點是晶體尺寸小耐沖擊，如果用自磨機加工破碎，顆粒多為球狀顆粒，表面干潔，易于結合劑結合。
 
白剛玉密度：
 
密度分為兩種，一是白剛玉堆積密度，二是白剛玉真密度。
 
白剛玉堆積密度為：1.53~1.99g/cm3，磨料的堆積密度與磨料的粒度，粒度組成，品種，顆粒形狀等因素都有關，一般來說，粗粒度磨料比細粒度磨料堆積密度大，混合粒度磨料的堆積密度大于單一的粒度密度。
 
白剛玉顆粒密度為：3.95~4.0g/cm3，近年鞏義市滿堂紅磨料磨具廠的精鑄專用剛玉真密度已達到4.1g/cm3，磨料的真密度是指單位體積（排除開氣孔的體積）內所含磨料的質量。   
 
白剛玉基本粒度為：45%~55% ，基本粒度是保證研磨效果的重要指標，在生產時應可以適當控制，但生產速度可能放緩。

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.
