Reduced crystalline silica diatomaceous earth products and methods of manufacturing the same |
| abstract |
Diatomaceous earth products with reduced amounts of cristobalite and higher Y values are disclosed. The diatomaceous earth products are prepared in a conventional manner to produce a flux-calcine diatomaceous earth. The flux-calcine diatomaceous earth is mixed with potassium hydroxide and the mixture is then heated. The combination of the potassium hydroxide and post-calcining heat treatment results in a diatomaceous earth product with reduced amounts of cristobalite and a whiter, brighter appearance. |
