Abstract
Abstract A method of depositing a metallic material onto a non-metallic substrate by depositing electrostatically charged particles of an admixture or solution including a thermally decomposable metal salt and a combustion retarding solvent to the non-metallic substrate. The non-metallic substrate is heated to an elevated temperature prior to the transference of the admixture to the substrate. The combustion retarding constituent of the admixture tends to partially decompose and vaporize at the elevated temperature of the non-metallic substrate and the metal salt tends to thermally decompose depositing a metallic material onto the non-metallic substrate. If the substrate is heated to a sufficiently high temperature, the metallic material tends to diffuse into a non-metallic substrate such as glass to thereby alter the color of the substrate. The solution to be formed into electrostatically charged particles contains a metal salt and a combustion retarding solvent.

Claims Analysis
Total Claims: 16
Claim 1
Independent Claim
40 words
The method of claim 1, wherein the metal of the metal salt is Co, Pb, Mn, Ce, Cr, Ag, Au, B, Mo, Ni, Fe, Sn, Cu, Va, Zr, Ca, Zn, Ba, Ta, La, Nd, Nb or Cd or combinations thereof.
Claim 2
Dependent Claim
31 words
The method of claim 2, wherein the substrate is glass, the thermally decomposable metal salt is cobalt octoate or manganese octoate and the halogenated solvent is trichlorethylene, carbon tetrachloride or perchlorethylene.
Claim 3
Dependent Claim
27 words
The method of claim 1, further including the step of diffusing at least a portion of the metallic material into the substrate by the application of heat.
Claim 4
Dependent Claim
26 words
The method of claim 3, wherein the cobalt octoate and the manganese octoate each contain up to about 6 weight percent of either cobalt or manganese.
Claim 5
Dependent Claim
25 words
The method of claim 1, wherein the ogranic solvent is an alcohol, polyol, ester, ketone, glycol ether, aromatic hydrocarbon or terpene hydrocarbon or combinations thereof.
Claim 6
Dependent Claim
43 words
The method of claim 1, wherein the substrate is glass heated to about its softening point temperature for a sufficient period of time whereby the metallic material diffuses into the glass to a depth of several Angstroms or more thereby tinting the glass.
Claim 7
Dependent Claim
15 words
The method of claim 7, wherein the substrate is a soda-lime, soda-lime-silica or ptoash-lead glass.
Claim 8
Dependent Claim
14 words
A substrate having metal deposited thereon in accordance with the method of claim 1.
Claim 9
Dependent Claim
103 words
A solution adapted to be formed into electrostatically charged particles for deposition upon a substrate of glass, refractory oxide, ceramic or semiconductor material, the solution containing a vaporizable flame retarding halogenated solvent and a thermally decomposable organo metal salt in an organic solvent wherein the metal salt dissolved includes a metal of the Group II, Group III, Group IV, Group V, Group VI, Group VII or Group VIII metals or combinations thereof of the Periodic Table of Elements and an organo radical of an octoate, napthenate, resinate, stearate, linoleate, borate, acetate, tallate, or monocarboxylic acid having a C9, C10 or C11, chain length.
Claim 10
Dependent Claim
25 words
The solution of claim 10, wherein the metal salt includes up to about 30 weight percent metal of the total weight of the metal salt.
Claim 11
Dependent Claim
30 words
The solution of claim 11, containing up to about 2 weight percent of the metal salt, up to about 68 weight percent organic solvent, the remainder essentially the halogenated solvent.
Claim 12
Dependent Claim
40 words
The solution of claim 12, wherein the metal of the metal salt is Co, Pb, Mn, Ce, Cr, Cu, Ag, Au, B, Mo, Ni, Fe, Sn, Va, Zr, Ca, Zn, Ba, Ta, La, Nd, Nb or Cd or combinations thereof.
Claim 13
Dependent Claim
47 words
The coating solution of claim 12, wherein the metal salt includes a metal selected from the group consisting of Co, Mn, Zn, Fe or Cr or combinations thereof, wherein the organic solvent is an aromatic hydrocarbon, and wherein the halogenated solvent is trichlorethylene, carbon tetrachloride or perchlorethylene.
Claim 14
Dependent Claim
130 words
In the manufacture of tinted glass, the steps comprising passing glass through a particle deposition zone, the glass heated to at least its softening point temperature, supplying to said particle deposition zone electrostatically charged particles of an admixture including a chlorinated solvent and an organo metallic salt having aN organo radical selected from the group consisting of an octoate or napthenate or monocarboxylic acid having a C9, C10 or C11 chain length, the organo metallic salt dissolved in an aromatic hydrocarbon solvent, the admixture particles attracted to and substantially uniformly deposited upon the glass, decomposing the organo metallic salt thereby coating the glass with a metallic material and vaporizing the solvents, and the heat associated with the glass causing the metallic material to at least partially diffuse into the glass.
Claim 15
Dependent Claim
52 words
In the manufacture of tinted glass as claimed in claim 15, wherein the metal of the metal octoate or napthenate or monocarboxylic acid having a C9, C10 or C11 chain length is selected from the group consisting of Co, Pb, Cu, Ca, Ce, Zr, Zn, Mn, Fe or Cr or combinations thereof.
Claim 16
Dependent Claim
22 words
In the manufacture of tinted glass as claimed in claim 16, wherein the glass is a soda-lime, lime, soda-lime-silica or potash-lead glass.
