Silicon Monoxide Gas Generation Preventing Raw Material Vapor Deposition
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In existing silicon monoxide gas generation methods, a portion of the generated silicon monoxide gas flows back into the supply unit and vapor-deposits, leading to a decrease in yield of the SiO-making material.
Innovation Solution
Inert gas is flowed through the raw material supply unit to prevent silicon monoxide gas from flowing back and vapor-depositing, with the inert gas flow rate controlled to maintain a pressure range of 0 Pa to 100 Pa in the reaction chamber, ensuring continuous generation of silicon monoxide gas.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If the silicon monoxide gas-generating raw material is continuously charged into the reaction chamber, then the productivity is improved, but the silicon monoxide gas flows back into the supply unit and vapor-deposits, causing loss of substance
Solution Approach 1:
Inert gas is introduced as an intermediary substance to flow through the raw material supply unit in the charging direction. This intermediary gas creates a protective flow that prevents silicon monoxide gas from flowing back into the supply unit, thereby preventing vapor-deposition of the raw material and eliminating substance loss while maintaining continuous operation
Solution Approach 2:
An inert gas atmosphere is established in the raw material supply unit to prevent harmful back-flow of silicon monoxide gas. The inert gas creates a controlled environment that protects the raw material from unwanted vapor-deposition while allowing continuous charging and reaction to proceed
