Claims Analysis
Total Claims: 10
Claim 1
Independent Claim
113 words
A method of providing a substrate with a refractory oxide coating comprising contacting the substrate with a dispersion of a solid particulate phase in a liquid phase, subsequently followed by firing to produce the coating, the dispersion comprising at least a first and a second refractory oxide component, characterised in that the first refractory oxide component is obtained from a purifiable liquid or solid precursor therefor and constitutes part at least of the solid phase, and the second refractory oxide component is either obtained from a purifiable liquid or solid precursor therefor and constitutes part of the solid phase or is a purifiable liquid precursor constituting part at least of the liquid phase.
Claim 2
Independent Claim
113 words
A method of providing a substrate with a refractory oxide coating comprising contacting the substrate with a dispersion of a solid particulate phase in a liquid phase, subsequently followed by firing to produce the coating, the dispersion comprising at least a first and a second refractory oxide component, characterised in that the first refractory oxide component is obtained from a purifiable liquid or solid precursor therefor and constitutes part at least of the solid phase, and the second refractory oxide component is either obtained from a purifiable liquid or solid precursor therefor and constitutes part of the solid phase or is a purifiable liquid precursor constituting part at least of the liquid phase.
Claim 3
Dependent Claim
16 words
A method as claimed in Claim 1, wherein the first refractory oxide component is an alumina.
Claim 4
Dependent Claim
21 words
A method as claimed in Claim 2, wherein the alumina is made by the hydrolysis of a liquid organo aluminium compound.
Claim 5
Dependent Claim
16 words
A method as claimed in Claim 3, wherein the liquid organo aluminium compound is aluminium sec-butoxide.
Claim 6
Independent Claim
28 words
A method as claimed in any of the preceding claims, wherein the second refractory oxide component comprises a water-soluble silicone constituting part at least of the liquid phase.
Claim 7
Dependent Claim
15 words
A method as claimed in Claim 5, wherein the silicone is a silicone glycol copolymer.
Claim 8
Dependent Claim
13 words
A method as claimed in Claim 6, wherein the copolymer is dimethicone copolyol.
Claim 9
Independent Claim
29 words
A method as claimed in any of Claims 1 to 4, wherein the second refractoryoxide component comprises a quarternary ammonium silicate constituting part at least of the liquid phase.
Claim 10
Independent Claim
15 words
A method as claimed in any of the preceding claims wherein the substrate is non-metallic.
