The role and advantages of garnet micropowder as a filler
The role and advantages of garnet micropowder as a filler are as follows:
1. Role
Enhance material performance
Garnet micropowder can replace 20%-30% of brown corundum in resin abrasives to improve the hardness, toughness and edge retention of abrasives . As a functional filler, its high density and wear resistance can optimize the durability of wear-resistant materials such as highway pavements and runways .
Improve high temperature stability
In composite materials (such as modified boron phenolic resin), garnet micropowder can significantly improve heat resistance and ablation resistance, form a dense ceramic layer at a high temperature of 1100℃, and reduce the ablation rate .
Improve processing results
As a precision grinding filler, its uniform particles and low scratch characteristics are suitable for optical glass, semiconductors, precision casting and other fields to improve the processing surface accuracy .
2. Advantages
Excellent physical properties
High hardness (7.5-8.0), high density (4.2g/cm³), providing strong wear resistance and pressure resistance;
Uniform particles and sharp edges, high processing efficiency.
Strong chemical stability
High temperature and corrosion resistance, stable under complex working conditions, especially suitable for high temperature and high pressure environments.
Economic and environmentally friendly
Low breakage rate, can be recycled 5-10 times, reducing consumables costs;
Low free silicon, no heavy metals, in line with environmental standards (ISO 11126, etc.).
Versatile adaptability
It has both thermal and electrical conductivity, and can be used in electronic device heat dissipation modules or conductive materials; at the same time, it can be used as a filter medium or water jet abrasive, and has a wide range of uses.
