高溫煅燒磨料是在原棕剛玉生產(chǎn)過程中進(jìn)行高溫煅燒，然后再進(jìn)行燜火處理。其主要特點(diǎn)為：膨脹系數(shù)非常小、親水性極好、韌性極高、強(qiáng)度大、制成的燒結(jié)磨具具有燒成后顏色深藍(lán)、不起網(wǎng)狀裂紋、無銹斑的特點(diǎn)，因此提高了磨具加工時的精度和磨削效果，尤其適應(yīng)生產(chǎn)高檔固結(jié)磨具。

This kind of Brown Fused Alumina grains is calcined at the high temperature, and with the anneal treatment.It is characterized by very low coefficient of linear expansion,very good hydrophilicity, good toughness and high hardness, producing the sintered grinding tools that is characterized by deep blue color after firing, without resillage, without rust and so on. So our this kind of product increase the precision and grinding ablity of the grinding tools in the using course. Brown Fused Alumina with high temperature treatment is applicable to make high quality bonded abrasives.
