What's the difference between meerschaum and sepiolite?
Meerschaum
Definition:
(n.) A fine white claylike mineral, soft, and light enough when in dry masses to float in water. It is a hydrous silicate of magnesia, and is obtained chiefly in Asia Minor. It is manufacturd into tobacco pipes, cigar holders, etc. Also called sepiolite.
(n.) A tobacco pipe made of this mineral.
Example Sentences:
Sepiolite
Definition:
(n.) Meerschaum. See Meerschaum.
Example Sentences:
(1) Sepiolite from Franklin is of moderate crystallinity and consists of soft, flexible mass-fiber.
(2) The results obtained allow the conclusion that the collagen-sepiolite complexes are adhesive for cells.
(3) Asbestiform sepiolite has been found in a zinc deposit at Franklin, New Jersey.
(4) Sepiolite is manganoan, while talc contains little manganese, suggesting differences in manganese substitution in these minerals and providing evidence against solid-state replacement.
(5) To determine whether O2- was elicited in response to a variety of asbestiform fibres, AM lavaged from Fischer 344 rat lungs were exposed in vitro to equivalent non-toxic amounts of crocidolite asbestos, erionite, Code 100 fibreglass, sepiolite, and their non-fibrous analogues, riebeckite, mordenite and glass particles.
(6) F contents of tibiae from the sepiolite group (at 60 or 90 d of age) were plotted against tibia F concentrations from groups receiving additional sodium fluoride in the diet.
(7) Pseudomorphous foliated texture and cross-cutting relationships indicate replacement of talc by sepiolite.
(8) A modified fluoride (F) bioassay procedure based on the method of standard additions and using chicks was tested for the determination of F availability in sepiolite.
(9) The data presented here suggest that talc can be unstable in a low-temperature hydrothermal environment, altering under certain conditions to form sepiolite.
(10) The fact that sepiolite has been previously unrecognized and misidentified at Franklin is a case in point.
(11) Comparison with other sepiolite samples suggests that increased crystallinity among sepiolites parallels increased fiber length, while disorder appears to be associated with flexibility.
(12) On the basis of their classification are chosen standards: sepiolite, wollastonite, palygorskite, etc., and their dispersion in needle-like fine dispersive particles, is studied.
(13) According to these studies the sepiolite-collagen complexes do not modify the studied features of the fibroblasts.
(14) Compared with fluoride from NaF, the relative bioavailability of fluoride from sepiolite was found to be very weak.
(15) Sepiolite, a magnesium silicate, binds collagen resulting in a complex which has a gel-like structure when hydrated.
(16) Attapulgite (palygorskite) and sepiolite are fibrous clay minerals used commercially as components in a wide variety of products including oil and grease adsorbents, carriers for pharmaceuticals, cosmetics, and pesticides.
(17) chrysotile with short fibers, UICC crocidolite, amosite, and 19 non-asbestos samples such as, glass fibers, calcium silicates, sepiolites and some clay minerals.
(18) The studies reported here are part of a series of experiments designed to characterize connective tissue cell response to sepiolite (magnesium silicate)-collagen complexes.
(19) These results indicate that fluorine from sepiolite was not available.
(20) Similarities in composition and other analytical parameters may cause sepiolite to be mistaken for fibrous talc or chrysotile in environmental samples.
