Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Ceramic substrates for electronic vaporization devices face a challenge in balancing compressive strength with porosity and e-liquid guiding rate, as increasing sintering temperature to enhance compressive strength often reduces porosity and e-liquid supply efficiency.
Innovation Solution
A ceramic substrate composition comprising 10-70 wt% silicon carbide, 6-60 wt% aluminum oxide, 5-45 wt% silicon dioxide, and 0-15 wt% glass powder, optimized to maintain or increase porosity and e-liquid guiding rate while improving compressive strength, using a specific sintering temperature and process to achieve desired thermal conductivity and bonding.

1Strength
If sintering temperature is increased to improve compressive strength of ceramic substrate, then compressive strength is improved, but porosity is reduced and e-liquid guiding rate deteriorates
Solution Approach 1:
The patent optimizes the sintering temperature parameter to a specific range (1000-1400°C) that balances compressive strength development with porosity preservation. This parameter optimization allows the ceramic substrate to achieve sufficient mechanical strength while maintaining adequate pore structure for e-liquid transport
Solution Approach 2:
The patent employs a composite ceramic material system comprising multiple components (silicon carbide, aluminum oxide, silicon dioxide, and glass powder) in specific proportions. This composite formulation enables the material to achieve both high compressive strength and maintained porosity through synergistic effects of different ceramic phases
