吸胶量低 粘度低 细粉白刚玉200#-0 耐高温铸造芯原材料白刚玉

吸胶量低 粘度低 细粉白刚玉200#-0 耐高温铸造芯原材料白刚玉以铝氧化粉为原料，经电熔提炼结晶而成， 纯度高、自锐性好、耐酸碱腐蚀、耐高温、磨削能力强、发热量小、效率高、,热态性能稳定它硬度略高于棕刚玉，韧性稍低。

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.
