Silicon carbide - Wikipedia

Silicon carbide (SiC), also known as carborundum (/ ˌ k ɑːr b ə ˈ r ʌ n d əm /), is a semiconductor containing silicon and carbon.It occurs in nature as the extremely rare mineral moissanite.Synthetic SiC powder has been mass-produced since 1893 for use as an abrasive..

Effect of borate addition on the sintered properties of …

2007/8/1· PFA from a major coal-fired power station in the UK has been formed into monolithic ceramic samples using dry powder compaction and sintering. Borax pentahydrate (Na 2 B 4 O 7 ·5H 2 O), anhydrous borax (Na 2 B 4 O 7 ) and boric acid (H 3 BO 3 ) were individually added to the PFA and the effects of firing between 1000 and 1200 °C have been investigated.

Sculpture - Wikipedia

Sculpture is the branch of the visual arts that operates in three dimensions.It is one of the plastic arts.Durable sculptural processes originally used carving (the removal of material) and modelling (the addition of material, as clay), in stone, metal, ceramics, wood and other materials but, since Modernism, there has been an almost complete freedom of materials and process.
