506-66-1 Usage
Chemical Properties
Red cubic crystal; hard and refractory; density 1.90 g/cm3; decomposes when heated above 2,100°C; reacts with water.
Uses
Different sources of media describe the Uses of 506-66-1 differently. You can refer to the following data:
1. Nuclear reactor core material: Schwartz, US 3170812 (1965 to USAEC).
2. Beryllium carbide (Be2C) is used for the cores in nuclear reactors.
3. Beryllium acetylide is used in a nuclear reactor as core material,Nuclear reactor core material: Schwartz.
Preparation
Beryllium carbide is prepared by heating the elements beryllium and carbon at elevated temperatures (above 900°C). It also may be prepared by reduction of beryllium oxide with carbon at a temperature above 1,500°C:
2BeO + 3C → (1500℃)→ Be2C + 2CO
Beryllium carbide decomposes very slowly in water:
Be2C + 2H2O → 2BeO + CH4
The rate of decomposition is faster in mineral acids with evolution of methane. However, in hot concentrated alkalies the reaction is very rapid, forming alkali metal beryllate and methane:
Be2C + 4NaOH → 2Na2BeO2 + CH4
Check Digit Verification of cas no
The CAS Registry Mumber 506-66-1 includes 6 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 3 digits, 5,0 and 6 respectively; the second part has 2 digits, 6 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 506-66:
(5*5)+(4*0)+(3*6)+(2*6)+(1*6)=61
61 % 10 = 1
So 506-66-1 is a valid CAS Registry Number.
