電路板灌封膠白剛玉325#

高純電路板灌封膠防開裂用微粉細(xì)粉白剛玉325#是以鋁氧化粉為原料，經(jīng)電熔提煉結(jié)晶而成， 純度高、自銳性好、耐酸堿腐蝕、耐高溫、磨削能力強(qiáng)、發(fā)熱量小、效率高、,熱態(tài)性能穩(wěn)定它硬度略高于棕剛玉，韌性稍低。用其制成磨具，適用于磨削高碳鋼、高速鋼及不銹鋼等細(xì)粒度磨料還可以用于精密鑄造和耐火材料。

White fused alumina was made from the high quality alumina by melting above 2000 in the electric arc furnace and cooling. It is white with the main crystal phase alpha-Al2O3.The white alumina produced in titling electric arc furnace has the advantage of high bulk density and low porosity and the volume stability and thermal shock resistance can be improved.
