Application
碳酸钙可用作：
- 在从煤焦油沥青制备多孔石墨碳材料的过程中，使用一种绿色合成方法，其中涉及到三种关键组分：模板、石墨化催化剂和活化剂。
- 以二氧化钛（TiO2）为原料，采用溶胶-凝胶法制备钛酸钙（CaTiO3）钙钛矿材料。钛酸钙可用于制造大规模、低成本和可持续的太阳能电池。
- 催化剂有助于提高燃料电池的性能和耐久性，从而促进清洁能源技术的发展。
General description
碳酸钙是一种无机化合物，难溶于水，但极易溶于稀酸。它在材料科学中起着至关重要的作用，特别是在太阳能电池、电池和超级电容器的发展中。在太阳能电池中，它作为钙钛矿层的前体材料，提高了钙钛矿太阳能电池的稳定性和性能。此外，碳酸钙被用于电极生产，作为阴极或阳极材料的导电添加剂，从而提高电池的整体性能和耐用性。

The mineralization of perfluorinated alkyl substances (PFASs) by calcium compounds during the waste thermal treatment was systemically studied. Different calcium compounds showed different mineralization efficiencies of PFASs during the thermal process, owing to the different reaction mechanisms. Calcium hydroxide was
