Kaolinite is a clay mineral, part of the group of industrial minerals with the chemical composition Al2Si2O5(OH)4. It is a layered silicate mineral, with one tetrahedral sheet of silica (SiO
4) linked through oxygen atoms to one octahedral sheet of alumina (AlO
6) octahedra. Rocks that are rich in kaolinite are known as kaolin or china clay.
The city of Sandersville is the county seat of Washington County, Georgia, United States. The population was 5,912 at the 2010 census. It is also a part of the Central Savannah River Area.
Porcelain is a ceramic material made by heating materials, generally including a material like kaolin, in a kiln to temperatures between 1,200 and 1,400 °C. The toughness, strength, and translucence of porcelain, relative to other types of pottery, arises mainly from vitrification and the formation of the mineral mullite within the body at these high temperatures. Though definitions vary, porcelain can be divided into three main categories: hard-paste, soft-paste and bone china. The category that an object belongs to depends on the composition of the paste used to make the body of the porcelain object and the firing conditions.
Brasso is a metal polish designed to remove tarnish from brass, copper, chrome and stainless steel. It is available either directly as a liquid or as an impregnated wadding pad.
The partial thromboplastin time (PTT) or activated partial thromboplastin time is a blood test that characterizes coagulation of the blood. A historical name for this measure is the kaolin-cephalin clotting time (KCCT), reflecting kaolin and cephalin as materials historically used in the test. Apart from detecting abnormalities in blood clotting, partial thromboplastin time is also used to monitor the treatment effect of heparin, a widely prescribed drug that reduces blood's tendency to clot.
Dickite is a phyllosilicate clay mineral named after the metallurgical chemist Allan Brugh Dick, who first described it. It is chemically composed of 20.90% aluminium, 21.76% silicon, 1.56% hydrogen and 55.78% oxygen. It has the same composition as kaolinite, nacrite, and halloysite, but with a different crystal structure (polymorph). Dickite sometimes contains impurities such as titanium, iron, magnesium, calcium, sodium and potassium.
Hard-paste porcelain, sometimes "true porcelain", is a ceramic material that was originally made from a compound of the feldspathic rock petuntse and kaolin fired at very high temperature, usually around 1400 °C. It was first made in China around the 7th or 8th century, and has remained the most common type of Chinese porcelain.
Bone china is a type of porcelain that is composed of bone ash, feldspathic material, and kaolin. It has been defined as "ware with a translucent body" containing a minimum of 30% of phosphate derived from animal bone and calculated calcium phosphate. Bone china is the strongest of the porcelain or china ceramics, having very high mechanical and physical strength and chip resistance, and is known for its high levels of whiteness and translucency. Its high strength allows it to be produced in thinner cross-sections than other types of porcelain. Like stoneware it is vitrified, but is translucent due to differing mineral properties.
Body powder is the generic name for alternatives to talcum powder. It is usually made from a combination of tapioca flour, rice flour, cornstarch, kaolin, arrowroot powder, and/or orrisroot powder, but also other powders may be used. In addition, water absorbing and water binding agents may be added such as polyacrylamide.
The Sandersville Railroad was originally operated from Tennille, Georgia, to Sandersville, Georgia and chartered in 1893 as a subsidiary of the Central of Georgia Railroad.
Saint-Yrieix-la-Perche is a commune in the Haute-Vienne department in the Nouvelle-Aquitaine region in west-central France.
Kaolin spray is a pest control that has kaolin as the main ingredient. The practice has been in recorded use from 2000 B.C.E. in China. More recent studies have shown that kaolin sprays can promote photosynthesis and are effective in reducing insects and disease on plants.
Metakaolin is the anhydrous calcined form of the clay mineral kaolinite. Minerals that are rich in kaolinite are known as china clay or kaolin, traditionally used in the manufacture of porcelain. The particle size of metakaolin is smaller than cement particles, but not as fine as silica fume.
