Kaolin, also known as China clay, is a naturally occurring clay mineral primarily composed of aluminium silicate. It is widely used in ceramics, medicine, and as a food additive.
Step 2: Analyzing the options.
(A) Magnesium silicate: This is incorrect as kaolin is not composed of magnesium silicate.
(B) Aluminium silicate: Correct — Kaolin is primarily made of aluminium silicate, which gives it its characteristic properties.
(C) Magnesium phosphate: This is incorrect as kaolin does not contain magnesium phosphate.
(D) Aluminium phosphate: Kaolin does not consist of aluminium phosphate.
Step 3: Conclusion.
The correct answer is (B) Aluminium silicate as kaolin is primarily composed of aluminium silicate.
