    摘要: A method for preparing a suspension of LDH particles comprises the steps of preparing LDH precipitates by coprecipitation to form a mixture of LDH precipitates and solution; separating the LDH precipitates from the solution; washing the LDH precipitates to remove residual ions; mixing the LDH precipitates with water; and subjecting the mixture of LDH particles and water from step (d) to a hydrothermal treatment step by heating to a temperature of from greater than 80° C. to 150° C. for a period of about 1 hour to about 48 hours to form a well dispersed suspension of LDH particles in water.

    摘要: The present invention is directed to a method of making metal oxide and mixed metal oxide particles. The method includes treating a mixture formed from a metal source, such as metal alkoxide, a surfactant, and a first alcohol in an aqueous media at a very high metal oxide yield. The mixture is reacted using a catalyst to form metal oxide particles having a desired particle size in said mixture. The method is particularly suitable for forming silica particles. The metal oxide particles can then be heat treated to form synthetic fused metal oxides such as, for example, synthetic fused silica.

    摘要: A reactor for the wet-chemical co-precipitation of oxide powders includes a cylindrical structure having first and second ends and a lumen extending the length of the tube. A central axis extends through the lumen. The first end is closed. The reactor also includes a first inlet port disposed proximal to the first end of the cylindrical structure and providing access through the cylindrical structure to inject a first reactant solution. The reactor further includes a second inlet port disposed proximal to the first end of the cylindrical structure and providing access through the cylindrical structure to inject a second reactant solution. The first and second inlet ports are disposed on opposite sides of the cylindrical structure and are coaxial relative to the central axis.
