AI Technical Summary
Minute inorganic oxide hollow particles used in electronic materials tend to become electrostatically charged due to collisions and friction, leading to particle aggregation and electrostatic discharge, which poses handling issues and potential damage to electronic devices.
Incorporating a specific amount of carbon into hollow inorganic oxide particles, specifically within a range of 0.0060 to 0.055 mass%, to suppress static electricity, with a volume resistivity of 1 × 10^16 Ω·cm or less, and ensuring a closed hollow structure with a carbon presence in the outer shell and partitions.
The solution effectively suppresses static electricity, preventing particle aggregation and electrostatic discharge, thereby improving handling properties and ensuring the safety of electronic devices.
