    摘要： In order to manufacture a light, open-pored, mineral insulating board with a gross density below 130 kg/m.sup.3 the following steps are employed:a) producing a water-solids suspension by intensive mixing of the following raw materials in an intensive mixer with a rotating mix container and a mixer mechanism rotating at a higher speed, using water and, in each case referred to the total content of solids, 40 to 48 M % (mass percent) quartz flour with a specific surface area according to BET of at least 2.5 m.sup.2 /g, 15 to 20 M % slaked lime with a specific surface area of at least 15 m.sup.2 /g, 25 to 35 M % cement, 0.3 to 0.5 M % hydrophobic medium, the rest additives, wherein the ratio of cement to slaked lime amounts to 1.5 to 2.3:1, the binder proportion lies in the range from 45 to 52 M % and the suspension has a water/solids factor (without foam) from 0.7 to 1.2,b) preparing a foam from water, air and a pore former, with a gross density from 40 to 50 kg/m.sup.3,c) introducing the foam into the water/solids suspension still present in the mix container with the intensive mixer running and mixing in the foam at a lower speed of rotation of the mixer mechanism within 120 seconds at the most,d) pouring the raw mix into at least one mold,e) allowing the raw mix to set to form a still plastic block having a sufficient green-state strength to allow it to be,f) lifting the plastic block off the mold bottom by means of a vacuum,g) cutting the block into individual insulating boards by means of wires andh) hardening the insulating boards in an autoclave.
