Glass-like Carbon has a pore-free and amorphous structure like that of glass and combines the features of carbon with those of glass.It has a high corrosion resistance, high hardness,high uniformity,and less particle. Considering the characteristics, Glass-like Carbon is used in Semiconducor Manufacturing Process, heat treatment Process etc. |

HITALOCK has such a nature that it is not easily attacked by ordinary solution of |
|
<HALOX> |
| |
acids, alkalis, of organic solvents.Chemical resistance is described in more detail in |

| |
Owing to HITALOCK's high thermal conductivity, heat generated at sliding part can be |

High heat resistance : |
|
Hitachi Chemical. Co, Ltd. |
| |
|
|
|
| |
Heat can hardly degrade the machanical strength and chemical properties of |
|
| |
HITALOCK. If ample oxygen exists, oxidation will be started at a temperature over 350° |
|
| |
C or so. When no oxygen is supplied, however, HITALOCK will not be oxidized even at |
|
| |
a higher temperature between 450°C and 500°C(dependant on grade). |
|
| |
High heat-shock resistance : |
|
| |
Coefficient of thernal expansion is very low as compared with that of other metal |
|
| |
materials. HITALOCK withstands a repetition of abrupt temperature change, incurring |
|
| |
little crack. It should also be noted that HITALOCK impregnated with resin or metal has |
|
| |
a somehow lower heat heat-shock resistance. |
|
| |
Self-lubricating property : |
|
| |
HITALOCK represents an outstanding self-lubrication, namely, it can be used without |
|
| |
lubrication. Owing to this important nature, HITALOCK is very suitable for use where |
|
| |
undersirable contamination by lubricant or similar accuracy to the case of ordinary |
|
| |
metal materials. |
|
| |
Excellent machinability : |
|
| |
HITALOCK has an excellent machinability, and can be machined on machine tools |
|
| |
such as lathes, drilling machines, milling machines, etc., obtaining the similar |
|
| |
accuracy to the case of ordinary metal materials. |

One of the major advantages of carbons is its porosity. By ipregnating the carbons with |
|
| |
a resin or the like in the pores, they can be made impervious. After such treatment, |
|
| |
carbons may be used as sealing materials. Further with this treatment, mechanical |
|
| |
strength such as compressive strength, bending strength, etc. of carbons can be |
|
| |
increased also along with its improved wear resistance. It should be noted that |
|
| |
consultation should be made with us for examination of your intended uses of |
|
| |
HITALOCK under any applicable regulations. |
