It is used for the various pumps valves and heat exchangers on the chemical production lineThe oil refining industry employs titanium materials for condenser tubes because of corrosion resistanceThis property also makes it useful for equipment used in the desalinization processTitanium is used in the production of human implants because.
Produce a powder with uniform chemical and physical propertiesIn manufacturing industrial plasters and gypsum cements a portion of the chemically combined water is removed by calcinationThe chemical equation that expresses the calcination of gypsum to form plaster is: caso 4 • 2h 2 o heat caso 4 • 12h 2 o 1-12h 2 o gypsum plaster.
The chemical formula is al 2 o 3Alumina imparts quick setting property to the cementClinkering temperature is lowered by the presence of the requisite quantity of aluminaExcess alumina weakens the cementMagnesia should not be present more than 2 in cement.
The ostwald process has many well-known uses in both the industrial and health field.
Upon further loss of water gypsum anhydrite is produced according to the following chemical equation: caso 4The presence of gypsum anhydrite is generally not desired in the alpha-hemihydrate gypsum process and care must be given to avoid further loss of water.
