摘要：

A method for calcining diatomaceous earth may include adding at least one lattice interfering agent to the diatomaceous earth to form a composite material. The method may further include heating the composite material at a temperature of at least about 800°C for at least about 15 minutes to form an at least partially calcined composite material. The at least one lattice interfering agent may include at least one cation of at least one of aluminum and titanium. A diatomaceous earth product may include the at least partially calcined composite material formed from the above- noted method for calcining diatomaceous earth. A filter aid may include the diatomaceous earth product.
