Frequently Asked Questions
Q: What is the primary advantage of using Calcined Mica Powder in welding electrodes?
Calcined mica offers extreme thermal stability and low moisture (0.11%), which prevents electrode porosity and improves arc stability during high-temperature welding processes.
Q: How does the 60mesh particle size benefit the final product?
The 60mesh size provides a precise distribution (99.9% +60mesh), ensuring a smooth, uniform coating on the electrode core, which is critical for consistent performance.
Q: Can this product be used in non-welding applications?
Yes, due to its purity and dielectric properties, it is widely used in electrical insulators, artificial marble, decorative stone paints, and general building materials.
Q: What are the shipping and packing options available?
We offer 20kg or 25kg packing in plastic woven or paper bags. For bulk orders, a 20GP container can load 12MT with professional palletization.
Q: What is the difference between Muscovite and Phlogopite mica powders?
Muscovite is generally preferred for its high electrical insulation, while Phlogopite is often chosen for applications requiring even higher temperature resistance.
Q: How do you ensure the purity of the non-metallic mineral products?
We utilize advanced calcination and purification processes, verified by strict chemical analysis to ensure purity levels reach 99.6% or higher.
