缩小这种差距的重要措施之一就是采用新一代的阴极内衬材料，其中最主要的就是阴极炭块。

One of the main ways to shorten these gaps is to employ new generation of cathode lining materials, especially the carbon cathodes.

在铝电解方面，氮化硅结合碳化硅远较阴极碳块耐腐蚀、抗氧化、电阻率高，是理想的电解槽侧壁内衬材料。

Compared with carbon, silicon nitride bonded silicon carbide has better oxidation resistance and bigger resistance ratio, which make it be a perfect line material of al electrolysis cell.
