Claims Analysis
Total Claims: 3
Claim 1
Independent Claim
79 words
A CERAMIC COATING COMPOSITION WHICH UPON DEPOSITION ONTO A SUBSTRATE SURFACE FORMS AN OXIDATION CATALYST CONSISTING ESSENTIALLY OF A PARTICULATE MIXTURE OF FROM 30 TO SUBSTANTIALLY OF A PARTICULATE MIXTURE OF FROM NEDYMIUM OXIDE, AND FROM 0.01 TO 20% PRASEODYMIUM OXIDE, SAID OXIDES BEING OF A PARTICLE SIZE RANGING FROM 0.5 MICRON UP TO -60 MESH, AND SMALL QUANTITIES OF A PARTICULATE FLAME CATALYST SELECTED FROM THE GROUP CONSISTING OF LANTHANUM OXIDE, SACNDIUM OXIDE, YTTRIUM OXIDE AND MIXTURE THEREOF.
Claim 2
Dependent Claim

A CERAMIC COATING COMPOSITION WHICH UPON DEPOSITION ONTO A SUBSTRATE SURFACE FORMS AN OXIDATION CATALYST CONSISTING ESSENTIALLY OF A PARTICULATE MIXTURE OF FROM 30 TO SUBSTANTIALLY OF A PARTICULATE MIXTURE OF FROM NEDYMIUM OXIDE, AND FROM 0.01 TO 20% PRASEODYMIUM OXIDE, SAID OXIDES BEING OF A PARTICLE SIZE RANGING FROM 0.5 MICRON UP TO -60 MESH, AND SMALL QUANTITIES OF A PARTICULATE FLAME CATALYST SELECTED FROM THE GROUP CONSISTING OF LANTHANUM OXIDE, SACNDIUM OXIDE, YTTRIUM OXIDE AND MIXTURE THEREOF.
Claim 3
Dependent Claim
76 words
THE METHOD OF APPLYING A CATALYSTIC REFRACTORY COATING ONTO A SURFACE WHICH COMPRISES INJECTING INTO A COMBUSTION ZONE THE MATERIAL DEFINED BY CLAIM 1, MAINTAINING THE TEMPERATURE AND RESIDENCE TIME OF SAID PARTICLES OF SAID MIXTURE IN SAID COMBUSTION ZONE AT A VALUE TO HEAT SUCH PARTICLES TO THEIR SINTERING TEMPERATURES, AND IMPINGING THE HOT PARTICLES ON THE SURFACE TO FORM A CRYSTALLINE DEPOSIT OF THE RESULTING SINTERED PARTICLES AS AN ADHERENT COATING ON SAID SURFACE.
