There are two main processes for the production of chromate salts in the world, calcium-roasting and non or little calcium roasting.
目前世界铬盐生产中存在着两大类主要的生产工艺，有钙焙烧和少钙或无钙焙烧。
It has shown that the antirust properties of calcium phosphite coatings are similar to the red lead antirusting coatings and superior to the zinc chromate or zinc phosphate antirusting coatings.
试验结果表明，亚磷酸钙涂料的防锈性能与红丹防锈涂料相当，优于锌铬黄、磷酸锌防锈涂料。
