Title:
光触媒コーティングを備えた基材
Document Type and Number:
Japanese Patent JP4485606
Kind Code:
B2
Abstract:
A glass, ceramic or glass-ceramic substrate (1), with a photocatalytic coating (3) of at least partially crystallised titanium oxide, is new. Pref. the crystallised titanium oxide is in anatase and/or rutile form, has a crystallisation degree of >=25 (pref. 30-80)% and is in the form of crystallites of average size 0.5-60 (pref. 1-50, esp. 10-40) nm. Also claimed are (i) non-soiling and/or non-misting, monolithic, double or laminated glazing incorporating the above substrate; and (ii) processes for prodn. of the above substrate (1) in which the coating is deposited by liq. phase pyrolysis (esp. from a soln. contg. one or more organo-titanium precursors of titanium chelate and/or titanium alcoholate type), by a sol-gel technique (by dip coating, spray coating or laminar coating) from a soln. contg. one or more organo-titanium precursors of titanium alcoholate type or by vapour phase pyrolysis (CVD) from one or more titanium precursors of halide or organo-metallic type.
