In addition, we control the total doping amount to be constant and change the relative proportion of silica and alumina in order to find a better mixing ratio to maximize the performance of antigen oxygen.
In addition, we control the total doping constant, changing the relative proportion of alumina oxide, in order to find a better mixing ratio to make the best anti-atomic oxygen performance.
In addition, we control the total amount of doping constant, change the relative proportion of silica alumina, the purpose is to find a better mixing ratio to make the best atomic oxygen resistance.
