优势Advantage:
与日本堺化学工业株式会社合作生产，产品质量和稳定性达到SOLVY、SAKAI的水平，并在国内外大型玻璃基板厂家中广泛使用。产品硬度高，粒子不易破碎。粉状产品在分散性和粒径方面特性好，有利于提高电子陶瓷电容的容量和缩小外观。Electrical strontium Carbonate is corporately produced by Kinglong and Japanese Sakai Chemical Industry Co Ltd, the quality and stability of which has achieved standard of SOLVY, SAKAI. They are widely used in glass substrate in domestic and foreign manufacturers. Good hardness, particles uneasy to be broken when transporting and mixing. Powder products have very good characteristics in the dispersion and particle size also, which contribute to improving capacitor capacity of electronic ceramic and narrowing its appearance.
