The studies indicate that different content of pyrophyllite and dolomite can cause the following three cases : ( 1 ) making the refractory point decrease linearly and, to some extent, influencing the microstructure and properties of sintered body ; ( 2 ) acceleratingmullite formation during sintering, reducing thermal expansion coefficient of bond, reinforcing the matching nature and improving the flexural strength and shock strength ; ( 3 ) preventing sic grinding tool from generating black core, expanding suitable sintering temperature range of sic grinding tool
同時，也不同程度地影響了磨具燒結體的微觀結構和性能； （ 2 ）可促進在燒結過程中莫來石的形成，降低結合劑的熱膨脹系數，加強了結合劑與磨料的匹配性，提高了磨具的抗折強度和抗沖擊強度； （ 3 ）在一定溫度范圍內還可防止碳化硅磨具出現黑心現象，拓寬了碳化硅磨具的燒結溫度適應范圍。 -
Experiments show the optimum content of pyrophyllite and dolomite is 30 % ; in contrast to original bond, the refractory point of bond is reduced by 55, the average coefficient of thermal expansion is reduced by 30 % and flexural strength and shock strength of grinding tool are increased by 27 % and 22 % respectively
通過實驗發現：葉蠟石和白雲石最佳含量為30 % ，與原結合劑相比，結合劑耐火度降低了55 ，平均熱膨脹系數降低了30 % ，磨具抗折強度提高了27 % ，磨具抗沖擊強度提高了22 % 。 -
