Abstract:
    The present invention belongs to the field of automobile tail gas purifying technology, and is especially glass ceramic coating on metal or alloy carrier of automobile tail gas purifying treater and its preparation process. The oxides of the glass coating include silica in 25-65 wt% and boron oxide in 5.0-27 wt%, except the mixture of other 3-9 oxides selected from 17 kinds of oxides, including sodium oxide, potassium oxide, lithium oxide, aluminum oxide, calcium oxide, etc. The glass coating on the metal carrier can raise the mechanical strength and reaction activity of the catalyst effectively, and this results in saving in active component and lowered cost.
