Abstract
The present invention provides a method for improving interfacial chemical reactions of a solid workpiece contacted with a liquid solution, said method comprising pre-heating the workpiece prior to immersion thereof in said liquid solution. The pre-heating may be carried out up to a temperature that is practicable without impairing the workpiece.
Claims4
A method for improving interfacial chemical reactions, said method comprising:
- a) pre-heating a workpiece, comprised of a substrate material, to a pre-heat temperature of about 100° C. or higher;
- and thereafter
- b) contacting said pre-heated workpiece at a pre-heat temperature of about 100° C. or higher with a liquid;
- wherein an interfacial chemical reaction occurs upon contacting said pre-heated workpiece with said liquid and the speed with which said interfacial chemical reaction occurs is faster than the speed wish which the reaction would occur without said pre-heating.
A method for improving interfacial chemical reactions, said method comprising:
- a) pre-hearing a workpiece, comprised of a substrate material, to a pre-heat temperature of about 70° C. or higher;
- and thereafter
- b) contacting said pre-heated workpiece at a pre-heat temperature of about 70° C. or higher with a liquid;
- wherein an interfacial chemical reaction occurs upon contacting said pre-heated workpiece with said liquid and the speed with which said interfacial chemical reaction occurs is faster than the speed with which the reaction would occur without said pre-heating and wherein the substrate material comprises a non-metal material.
A method for improving interfacial chemical reactions, said method comprising:
- a) pre-heating a workpiece, comprised of a substrate material, to a pre-heat temperature of about 70° C. or higher;
- and thereafter
- b) contacting said pre-heated workpiece at a pre-heat temperature of about 70° C. or higher with a liquid;
- wherein an interfacial chemical reaction occurs upon contacting said pre-heated workpiece with said liquid and the speed with which said interfacial chemical reaction occurs is faster than the speed with which the reactions would occur without said pre-heating and wherein the substrate material comprises silicon.
A method for improving interfacial chemical reactions, said method comprising:
- a) pre-heating a workpiece, comprised of a substrate material, to a pre-heat temperature of about 70° C. or higher;
- and thereafter
- b) contacting said pre-heated workpiece at a pre-heat temperature or about 70° C. or higher with a liquid;
- wherein an interfacial chemical reaction occurs upon contacting said pre-heated workpiece with said liquid and the speed with which said interfacial chemical reaction occurs is faster than the speed with which the reaction would occur without said pre-heating and wherein the pre-healing is accomplished using a process selected from the group consisting of infrared heating, induction beating, and microwave heating.
