A monolithic ceramic body can comprise a first portion comprising a plurality of pores defining an interconnected network of pores, and a second portion integrally formed with the first portion and defining at least a portion of a perimeter surface of the monolithic ceramic body, wherein the second portion can include at least one complementary engagement structure. In another embodiment, a porous ceramic assembly can comprise at least two of the monolithic ceramic bodies which are coupled to each other by a first complementary engagement structure and a second complementary engagement structure.

Monolithic ceramic body and assembly

A method for continuously forming a three-dimensional body from a mixture, the mixture comprising at least 15 vol % solid particles and a radiation curable material. The method allows the continuous production of three-dimensional bodies comprising to a high content ceramic particles at a forming speed of at least 25 mm/hour.

Method for forming a three dimensional body from a mixture with a high content of solid particles

A method of making a plurality of composite granules can include: forming green body granules comprising an aluminosilicate; heating the green body granules to form sintered granules; cooling the sintered granules according to a cooling regime, wherein the cooling regime comprises a temperature hold between 700&#xb0; C. and 900&#xb0; C. for at least one hour. In a particular embodiment, the aluminosilicate for making the composite granules can have a particle size less than 150 &#x3bc;m. The composite granules are particularly suitable as roofing granules and can have a desired combination of high solar reflectance SR and low lightness L*, a low bulk density, good weather resistance and strength.

The present disclosure relates to roofing granules, such as solar-reflective roofing granules having one or more of low crystalline silica content, high stain resistance and algae resistance. The present disclosure provides a mineral roofing granule having at its mineral outer surface a first fired mixture comprising an aluminosilicate clay, the first fired material having no more than 2 wt % crystalline silica. The present disclosure also provides a mineral roofing granule having a mineral body and a mineral outer surface, the mineral roofing granule having at its mineral outer surface a first fired material, the first fired material being a first fired mixture comprising an aluminosilicate clay; one or more of a feldspar, a sodium silicate and a nepheline syenite; and, optionally, a zinc source.
