| Product Description |
| |
1. K-Chamotte, a basic Refractory Material, is manufactured from Kaolin
which is
abundantly available in Kyongsang Namdo Province of Korea. |
| |
2. K-Chamotte has high Quality and excellent Uniformity because it is processed
through fine grinding and dearing Auger machine before being sintered. |
| |
3. K-Chamotte is most suitable for Fire Bricks, Refractory Castables and Refractory
Mortars because it, sintered at high temperature, has high Density and Thermal
Stability.
(K: 1620¡É, KA: 1600¡É, KC: 1580¡É) |
|
| |
| 4. Three types of K-Chamotte are supplied according to Refractoriness, with
a diameter of either 10mm or 17mm. |
| |
| 5. Especially, KA 1400 has very good Spalling Resistance, because of its high
porosity. |

| Product Description |
| |
1. KD-Chamotte has excellent Insulating Effects at high temperature
because of its
high Refractoriness and of high Porosity which is achieved
by letting crystallization
water of Halloysite evaporate during calcination. |
| |
2. KD-Chamotte is very good for Insulating Fire Bricks and Light
Weight Castable at
high temperature and also good for a Ceramic Filter
Agent, because of its high
porosity and good Adsorption. |
| |
|
|
|
|
| |
| 3. KD-Chamotte is supplied in two types. Clinker and
Crushed type. |

1. C-Chamotte is mainly composed of Cordierite which has lower thermal
expansion. It has good Spalling Resistance under rapid heating and cooling
process. |
| |
2. C-Chamotte has high Refractoriness Under Load even though its refractoriness
is comparatively lower (SK16). It is used for Sagger of Chinaware and Electronic
ceramics and also is used for Fire Bricks and Stonewares which require high
Spalling Resistance. |
