1.
Calcium
Metaborate
This is a new material
artificially made by synthetic method, which is widely
used in chemical industry in virtue of functions of fusion assistance, antiflaming,
drying speed-up and sterilization. It is often used as prime paint
of anti-rust paint, antiflaming paint, anti-fog agent and bactericide as well as
catalyzer in chemical industry. It is also a new material in non alkali glass
industry
and performs better than boric acid. It can be also used as antifreezer and lubricant.
Right amount of calcium metaborate added in gasoline or diesel oil will make the
fuels more efficient.
It is white or offwhite powder.
The molecular formula is Ca(BO2)22H2O or CaO·B2O2·2H2O.

2.
Calcium Boride
Molecular formula is CaB6. Its applications are
listed below: 1.
As boric additives used for making dolomite carbon bricks and magnesia
dolomite carbon bricks, to enhance the thermal strength, ability of
anti-oxidation and anti-corrosion;
2.
As raw materials used for making high purity metal boride such as TiB2,
ZrB2, HfB2 etc., and boron alloys such as Ni-B, Co-B, Cu-B etc.;
3.
Used for production of the mixture of activator Ca3B2N4 and hexagonal
nitride, which is the good material for making crystal cube B2N4 of excellent
performance;
4.
As a new material of neutron prevention in nuclear industry;
5.
Used as deoxidizer to enhance the strength of high conduction copper;
6.
Used as a new type of semiconductor for making the spinning electron
component of 900 K temperature;
7.
Used as boronizer with function of desulfurization and deoxygenation in
boron alloy;
8.
As the raw material for making boron trichloride and monolithic boron.

Yellow Flakes |
There
are yellow flakes and white or clear flakes.
Its major applications are as binder in making
refractories in metallurgical field as well as the raw material for producing
magnesium metal; used for making various magnesium salts in chemical field, such
as magnesium oxide, magnesium hydroxide, and magnesium carbonate, as well as the
raw material for making antifreeze, dust preventive, and flame-retardant; used
in building material field together with other materials to make magnesia cement,
abrasive stones, artificial marble, magnesia tile, glass fiber magnesia plate
etc.; as additive in food industry, such as to make the bean curd cured; used as
snow melting agent on icy road; and used for making magnesium fertilizer,
potassium magnesium fertilizer, and cotton defoliant in agriculture field.
