一般描述

碳酸钡是一种难溶于水的无机化合物。它可用于各种工业应用,特别是在陶瓷工业中可用于釉料并可作为助熔剂。它也可用于制造电子陶瓷、电容器、PTC热敏电阻和其它电子元件。

应用

碳酸钡可用于:    
  • 制备BaTiO3 纳米颗粒的前体,该纳米颗粒是一种可用于制造多层陶瓷电容器的介电材料
  • 钛酸钡薄膜合成的前体个,该薄膜在光伏器件中有应用。

碳酸钡也可用于以下应用:
  • BaCO3据报道,纳米颗粒已被用于固体氧化物燃料电池(SOFC)中高温氧还原反应(ORR)的催化剂。      
  • 基于碳酸钡的纳米材料已被用于传感器和催化应用,其采用一维纳米结构提高了传感性能。    
  • BaCO3可用于制造用于多层陶瓷电容器和复合氧化物以及PTC热敏电阻的钛酸钡。它还用于制造光学玻璃、半导体溅射玻璃,并可作为磷光体材料的成分。

特点和优势

  • 99.999% trace metals basis BaCO3 enhances performance in electronic ceramics and optics, improving the reliability of capacitors, insulators, and specialty glass by reducing impurities and increasing mechanical strength and refractive index.
  • Low impurity levels (<15ppm) in BaCO3 enhance the chemical resistance and durability of glass, making it suitable for high-quality applications.
