TALCtalc

Cas No.14807-96-6

Talc is the softest ore among minerals and has a kind of smoothness. Mohs hardness of talc is one which means you can scratch on the face of talc ore.
In Japan it’s called as kasseki and many years ago child used to play with it writing letters on the ground.
Wire abrasion of talc is small. And talc has such useful characteristics as chemical stability, insulation and chemical affinity to organic matter.
In order to take advantage of such characteristics, it is ground to fine powder and used for the materials of many products. And it is applied to many products such as paper, synthetics resin, rubber, medicine, cosmetics, ceramics and fertilizer.

MICAMica

Cas No.12001-26-2

Mica is a kind of aluminum silliate mineral, and it has the characteristic of glossiness and smoothness. When it is ripped off it peel off thin, plate like.
Mica is excel in insulation and heat – resistance and it has strength and elasticity. It is used for insulation materials and fillers of rubber and paint, As its aspect ratio and rigid rate is high, it’s used for the reinforcement of synthetic resin.

POTASH FELDSPARPotash Feldspar

Cas No.68476-25-5

Feldspar is a main mineral which forms ligneous rock and the most typical rock-forming minerals which quart and mica.
Feldspar consists of orthsoclase, ablite and anorthite. By chemical composition, it is divided to orthsoclase which includes K and albite which includes Na.
Above all, the feldspar which abounds in potassium is called K-Feldspar. As main usage, it is widely used for flat glass, sanitary ware and kiln industry.
The powder of K-Feldspar is used for not only paint, rubber, Synthetic resin but also abrasives and fireproof cement.

About asbestos

On August 8,2006, Ministry of Health , Labor and Welfare published a new asbestos control low「kiankahatu」no. 0828001 “ Methods of analysis of the asbestos content in a natural mineral”. And it had been enforced on September 1 the same year.

We surely analyze and confirm the talc ore and talc products by products rot numbers if it contains asbestos 0.1% or less by weight based on the law using most sophisticated instruments.

So, the customers are using our safe talc products at ease

Methods of analysis of the asbestos content in talc.

x-ray diffractometer:the instrument from PANAlytical firm Multipurpose x-ray diffractometer empyrean
2.Standard testing materials containing asbestos for talc:Standard test materials from Japan working circumstances measurement association
. Talc standard test material(containing 0.5%tromolite) JAWE1112
. Talc standard test material(containing 0.8%chrysolite)JAWE1212

3.Analysis procedure : a. measuring conditions for x-ray diffractometer  . Measuring scope (2θ) : tromolite 10-11°(around 10.4°)chrysolite 11-13°(around 12.1°)or 23-26°(around 24.3°)
 . Tube voltage and electric current : 40kV, 30mA
 . Counter negative pole : Cu
 . Mono coloring : Ni filter
 . Detector : semiconductor detector
 . slit system : using auto variable slit (irradiation width: 15mmfixed)
 . Gonio meter scanning speed : 1/8°
 . full scale : auto scale

4.Method of measurement : based on the methods of analysis from [Kianka] no.0828001

5.The way of Judgment : As the result of measurement ,if diffract line is not found or under the diffract line strength of the test materials , it is judged that testing talc’s asbestos does not go over 0.1% weigh.
