Studies on the Surface Area of Auto Catalyst Wash Coats

  title={Studies on the Surface Area of Auto Catalyst Wash Coats},
  author={Li Pei},
The studies on the surface area of the three substrates were discussed.The adoptive substrates were porous cordierites produced in china (A,B) and from abroad(C) with cell density of 62cell/cm 2. The samples of A,B and C were impregnated in the alumina solution kneading with the rare earth oxides,and their physical and chemical properties were tested.The results shows that the rare earth oxides were effective additives for improving the surface area and thermal stability,and the substrates C… CONTINUE READING
