Popular questions
What is magnesium carbonate good for?
As a food additive (E504(i)), it’s good for keeping powders free-flowing as an anti‑caking agent and serving as a carrier for flavors or colors; it can also help regulate acidity in some products.
Is magnesium carbonate good for you?
At the small amounts used in foods it’s considered safe (approved in the EU; GRAS in the U.S.) and contributes little nutritionally; high supplemental or medicinal doses of magnesium carbonate may cause laxative effects, especially in people with kidney issues.
How do you make magnesium carbonate?
It’s typically produced by precipitating it from magnesium salt solutions (e.g., magnesium chloride or sulfate) with sodium carbonate, or by carbonating magnesium oxide/hydroxide; it also occurs naturally as the mineral magnesite.
Is magnesium carbonate the same as magnesium citrate?
No—magnesium carbonate is the carbonate salt, while magnesium citrate is the citrate salt; citrate is more water‑soluble and often used as a supplement, whereas carbonate is less soluble and mainly used as an additive or antacid.
What is magnesium carbonate used for?
In foods it’s used as an anti‑caking agent and carrier (e.g., in table salt, spices, and powdered mixes), and sometimes as an acidity regulator or firming aid.
How to remove calcium silicate from pool?
Calcium silicate scale is very hard and relatively acid‑resistant, so it’s typically removed by mechanical means (pumice/scale pads or bead blasting) after lowering pH and using a sequestering agent; an acid spot test that doesn’t fizz helps confirm it’s silicate, not carbonate. Prevent recurrence by keeping water balanced (pH/alkalinity/calcium) and using a sequestrant.
What is calcium silicate board?
A rigid, noncombustible building/insulation board made from calcium silicate hydrates, valued for fire resistance, moisture tolerance, and dimensional stability. It’s used for fireproofing, lining stoves/flues, and thermal or acoustic insulation.
How to cut calcium silicate board?
Score‑and‑snap works for thin sheets; thicker boards are cut with a circular saw using a carbide or diamond blade at a slow feed rate. Control dust with wet cutting or HEPA extraction and wear PPE (respirator, eye protection, gloves).
Is calcium silicate bad for you?
As a food additive (E552) used mainly as an anticaking agent, it’s considered safe at permitted levels (JECFA ADI “not specified”; FDA GRAS). The main concern is inhaling fine dust in occupational settings, which can irritate the respiratory tract.
Is calcium silicate vegan?
Yes—it's a mineral/synthetic ingredient with no animal-derived components, so E552 is generally suitable for vegans.
