Growth and structure of CaCO3

25 03 2015  Organisms often employ non classical crystallisation mechanisms to create the remarkable materials that are biominerals These materials often surpass their synthetic counterparts in terms of physical properties morphologies and structural organisation The non classical mechanisms employed include the controlled formation transition and release of amorphous precursor material and the

Weathering

Physical weathering occurs when physical processes affect the rock such as changes in temperature or when the rock is exposed to the effects of wind rain and waves Water can get into cracks in a rock and if it freezes the ice will expand and push the cracks apart When the ice melts more water can get into the larger crack if it freezes

Conversion Formulas

Total Alkalinity is the amount of acid used to reach pH 4.5 ml x 50 000 mg CaCO3/eq / sample volume ml Here is an example on how to find Total Alkalinity 18ml of 0.01M of Sulfuric Acid was required to Titrate 50ml of your sample to pH 4.5 Total Alkalinity= 18 ml x 0.02 eq/L x 50 000 mg CaCO3/eq / 50 ml = 360 mg/L

Langelier Saturation Index LSI

23 01 2020  Langelier Saturation Index LSI was developed by Scientist Langelier in 1936 The LSI is used to determine the need for calcium carbonate precipitation scale control in water sources containing a TDS concentration of less than 10 000 mg/L LSI is most widely used tool to predict tendency of cooling water In order to calculate LSI five values

Water Hardness

In the U.S hardness is usually measured in ppm of CaCO3 A German dH is 17.8 ppm CaCO3 A molar concentration of 1 milliequivalent per liter mEq/l = 2.8 dH = 50 ppm Note that most test kits give the hardness in units of CaCO3 this means the hardness is equivalent to that much CaCO3 in water but does not mean it actually came from CaCO3.

Thermal Degradation CaCO3

12 08 2016  CaCO3 H2O > Ca OH 2 CO2 Because of the N2 atmosphere I think that the equilibrium is pushed to the right side When you look at the TGA curve the last 2 mass drops are caused by CaCO3/Ca OH 2 I would think the first mass drop is caused by Ca OH 2 degradation into CaO and H2O where H2O instantly evaporates.

Calcite

Calcite is a carbonate mineral and the most stable polymorph of calcium carbonate CaCO 3 .The Mohs scale of mineral hardness based on scratch hardness comparison defines value 3 as calcite . Other polymorphs of calcium carbonate are the minerals aragonite and vaterite.Aragonite will change to calcite over timescales of days or less at temperatures exceeding 300 °C and vaterite is even

Loss On Ignition

CaCO3 100.09 / CO2 44.01 = 2.274 So the part of the sample that is represented by the CaO is 2.274 times that of the known CO2 So to calculate the quantity of CaCO3 in a sample the weight lost between 550950 oC must be multiplied by 2.274.

Sustainability Oceanex

Most importantly the CaCo3 and other core ingredients of OCEANEX are bio renewable and they renew very quickly Of course the key benefit is that when used as a supplement in the high volume production of plastic products OCEANEX can potentially result in the saving of tons of petrochemical polymer every year and still deliver products that meet performance requirements.

Water Hardness Areas in the UK

Around 60 of the UK is classed as having hard or very hard water with many areas exhibiting over 200mg of calcium carbonate per litre Scaleguard is the cost effective and simple solution to tackling the problems caused by hard water.

Frequently asked questions on lowering hardness

04 10 2021  ClarkEnglish degrees of hardness are actually rarely used in the UK One degree Clark is equal to 14.3 mg/I CaCO3 Some argue that because Clark is the form of hardness we re supposed to use in the UK that this means that when we say GH we re actually talking about 14.3 mg/l CaCO3 rather than the 17.9 mg/l CaCO3 you d see if we were using dH.

The Marble Arch Caves near Enniskillen Co Fermanagh

As mentioned earlier Limestone is defined as containing at least 50 calcium carbonate and it s this CaCO3 which is easily dissolved by rain and soil water both of which are slightly acidic Therefore the most important factor in the continued growth of cave systems is water –the largest passages in the Marble Arch Caves have formed where there has been a constant source of water.
