Frequently Asked Questions (FAQs)

1. Is zinc oxide good for thermal paste?

Thermal interface material the type of thermal grease in the form of a composite is very suitable for use on the CPU. Sodium silicate as a matrix and zinc oxide as fillers has many advantages compared to silicon and metal as the raw material for making thermal grease for CPU which is widely used today.

2. Is zinc oxide thermal paste conductive?

It uses zinc oxide as the filler to achieve a thermal conductivity of 0.66 W/m·K. The product is electrically-insulating and non-corrosive with an operating temperature range of -40 to 200 °C. If higher performance is required, silver-based compounds can have a thermal conductivity of 3 to 8 W/m·K or more.

3. Does zinc oxide conduct heat?

For material science applications, zinc oxide has high refractive index, high thermal conductivity, binding, antibacterial and UV-protection properties.

4. What is the best alternative to thermal paste?

The best solutions turned out to be hair wax and toothpaste, which exhibited a relatively low temperature without completely drying out and cracking. If you're impatient or under a tight deadline and need to squeeze in a few hours of extra work, consider toothpaste or hair wax when nothing else is available.
