RefractoryWikipedia
A refractory material or refractory is a material that is resistant to decomposition by heat pressure or chemical attack and retains strength and form at high temperatures. Refractories are polycrystalline polyphase inorganic nonmetallic porous and heterogeneous. They are typically composed of oxides or non oxides like carbides nitrides etc. of the following materials silicon

The bulk density of soil depends greatly on the mineral make up of soil and the degree of compaction.The density of quartz is around 2.65 g/cm³ but the (dry) bulk density of a mineral soil is normally about half that density between 1.0 and 1.6 g/cm³. In contrast soils rich in soil organic carbon and some friable clays tend to have lower bulk densities (<1.0 g/cm³) due to a combination of
