【中文】灰钙即氧化钙，最先应用于建筑中的砌砖、砌墙、涂刷等，随着灰钙粉的用途不断被认识与认可，已在工业、农业、建筑及制造、食品业中都有广泛应用，具体的应用行业有：腻子粉、乳胶漆、保温砂浆、建筑涂料、电线电缆、塑钢门窗，还用于烟气脱硫、污水处理等。由于灰钙粉能够在较低的成本下赋予涂料优异性能，因而人们根据国家标准的新要求，将灰钙粉应用于合成树脂乳液涂料中，使涂料能够在较低的成本下满足GB/T 9756—2001和GB 18582—2001的要求，且涂料的容器中状态、流平性和涂膜的手感等均好。
【English】Gray calcium is calcium oxide. It was first used in construction for bricklaying, wall building and coating. As its uses have become increasingly recognized, it has been widely applied in industry, agriculture, construction, manufacturing and the food industry, specifically in putty powder, emulsion paints, insulation mortar, architectural coatings, wires and cables and plastic-steel doors and windows, as well as in flue gas desulphurization and wastewater treatment. Because gray calcium powder can give coatings excellent performance at relatively low cost, and in line with new national standard requirements, it is applied in synthetic resin emulsion coatings so that the coatings meet GB/T 9756-2001 and GB 18582-2001 at lower cost, with good container condition, levelling and film feel.
