Manufacturing of an artificial igneous rock material by a sintering process
A method of making a porous silicate based material with similar properties as an extrusive or intrusive igneous silicate based rock without being naturally occurring. Quartz sand with a silica content (SiO2) of more than 75% is mixed with Sodium oxide, Calcium oxide, and Aluminum oxide and heated up to a temperature of more than 960° C. and for the chemical reactions to take place and for the molten mixture to reach an elastic state where the viscosity allows the formed gasses to be dissolved into the melt. The sintering process may be at atmospheric pressure or at positive pressure. The material is then cooled to a solid. The process gives a porous igneous rock with micro cells based on CO2 bubbles made at a temperature prior to the molten mixture reaching a plastic state. The solid material may be milled and used as a filter material. In one aspect, the solid is milled, mixed with a foaming agent, melted and cooled in order to form an even more porous second solid material.
