Olivine does not contain chloride, there will be no corrosion and adhesion problems.
The iron (Fe2O4) in olivine is the most stable form of iron. Due to this feature, it does not react
chemically with the oxygen in the air and water. Therefore, since there will be no oxidation, the paint process
after cleaning will have a longer life.
Olivine does not contain free silica. And because of this feature, it does not cause silicosis disease. It
removes the health and safety concerns of the operators. Moreover, olivine is also used as a fertilizer in the
treatment of drinking water and in agriculture. However, silica sand contains free silica in its varieties and
creates a carcinogenic hazard for the users of this sand in terms of health. The use of minerals containing free
silica is prohibited in various countries (such as Norway, Sweden, England and the Netherlands) on the
grounds that they cause silicosis disease. In our country, the use of minerals containing free silica was banned
by the Ministry of Health in 2009.
It is environmentally friendly. It has no harmful effects on the environment.
The grain shape of the olivine is angular and this feature significantly increases the surface cleaning
speed.
The hardness of olivine is 6.5 -7, which is an important feature for its use as an abrasive material and
ensures high efficiency in surface cleaning.

Casting Sand made of olivine, with its sintering point at 1450 �ºC and melting point above 1760 �ºC, provides excellent
performance in iron castings (grey cast iron, nodular cast iron, tempered cast iron) and also performs well in non-
ferrous castings. Using olivine as casting sand, it contributes significantly to casting companies both financially and in
terms of quality. Especially in Mn castings, olivine is the definitive solution in these castings where surface roughness
is important. In addition, molds made of Olivine are preferred in problematic situations between the metal materials
poured during casting and the mold. Silica-containing sands react with the metal during casting, while the olivine
mold does not allow the metal to enter into its body. As Olivine's high magnesium content olivine sand, when used
with clays, increases its binding properties and significantly reduces the need for bentonite. Olivine's basic nature
makes it an ideal choice for manganese steel production. In contrast to silica sand, olivine sand does not interact
with manganese steels, keeping surface grinding costs to a minimum and giving high cleanliness casting results. Fine
grain olivine sand is also commonly used in brass, bronze and aluminum castings. This is relatively due to the
moisture-free properties of the material and the angularity of the particles. This property provides consistency and
low permeability, resulting in castings with very good surface treatment. The angular particles of olivine sand, even
when thoroughly crushed, ensure that it is still gas permeable after forging, which plays a very important role in the
escape of steam in castings. Olivine has a much higher return rate than silica sand. This is due to less upheaval and
less distortion in thermal shocks.
Fused mullite is made of high-purity quartz sand and industrial alumina, melted in super large electric arc furnace, and can be processed into particles, fine powders and micro powders with different sizes. It has white color, low carbon residue and well-developed acicular crystals. With the characteristics of low porosity, low impurity content, and good thermal shock resistance and wear resistance. It is widely used in glass kiln lining brick, alkali free glass sedimentation tank, hot blast stove brick of large smelting blast furnace, low creep sillimanite brick of blast furnace, ceramic kiln furniture, box antimony, shed plate, petrochemical industry and other industries.
