Calcium Bentonite vs. Sodium Bentonite The difference between calcium and sodium bentonite clay is the higher levels of those minerals. You can take calcium bentonite clay and add salt and it would be sodium bentonite. Calcium is also found at higher elevations and is a cleaner clay.
For foundries seeking improved mold density and dimensional control, Calcium Bentonite can deliver un to 25% greater green compression strength. Southern Bentonite''s compaction and adhesive properties also improve mold permeability, making it the ideal clay for foundrymen seeking improved surface finish with finer molding sands.

Dec 07, 2016· The global bentonite market size is expected to reach USD billion by 2024, according to a new report by Grand View Research, Inc. Rising product use as antiscalants in applications such as foundry sands and water treatment will .
Furthermore, sodium Bentonite clay contains calcium as an exchangeable ion and calcium Bentonite contains sodium as an exchangeable ion. To convert Calcium Bentonite to Sodium Bentonite just add a small amount of salt to a cup of clay and it will have more sodium exchangeable ions and therefore sodium Bentonite.
foundry Bentonite is used as a bonding material in the preparation of moulding sand for the production of cast iron, steel, and nonferrous casting. The unique properties of bentonite yield green sand moulds with good flowability, compactability, and thermal stability for the production of high quality castings.
FOUNDRY GRADE Description: Foundry is the oldest techniques developed by human Green sand casting is the most common technique, especially for ferrous castings. SWELLBOND ® selectively mining Bentonite for use in foundry green sand molding and other alloy castings. Advantages: High purity material, less sand content as fine powder.
Sodium bentonite and calcium bentonite are the main two product types available in the global bentonite market. The market was led by sodium bentonite in 2015 with a share of more than 60%. The scenario is anticipated to remain so over the forthcoming years, thanks to the increasing preference for green sand casting process in the foundry.
Sep 04, 2019· Calcium Bentonite vs. Sodium Bentonite. There are two types of bentonite clays. While calcium bentonite is used on the body, both internally and topically, sodium bentonite has more industrial uses. Sodium bentonite clay is used as a natural sealant, such as to seal roads, lagoons, landfills and ponds. It has natural swelling abilities ...
Jul 25, 2018· Southern (calcium) bentonite is used as a bond for sand mixtures. Southern bentonite bonded mixtures help to prevent hot cracking and hot tears in castings, as the molding and core sands shakeout freely without lumping. Has less dry, baked and hot compressive strengths than western bentonite bonded mixtures.
