QUESTION STATEMENT:द्विभाषी / Bilingual
नव आविष्कृत उच्च ताप अतिचालक है-
The newly discovered high-temperature superconductors are:
SELECT CORRECT OPTION:
A
मिश्र धातुएं
Alloys
B
शुद्ध दुर्लभ मृदा धातुएं
Pure rare earth metals
C
सिरेमिक ऑक्साइड
Ceramic oxides
Correct
D
अकार्बनिक बहुलक
Inorganic polymers
Official Solution & Explanation:
Correct Answer: Option C(सिरेमिक ऑक्साइड)
उच्च ताप अतिचालकों (High-Temperature Superconductors - HTS) में मुख्य रूप से सिरेमिक ऑक्साइड (Ceramic Oxides) जैसे यिट्रियम-बेरियम-कॉपर-ऑक्साइड (YBCO) या बिस्मथ/थैलियम क्यूप्रेट्स का प्रयोग किया जाता है।
High-temperature superconductors discovered since 1986 are primarily cuprate ceramic oxides (such as YBa2Cu3O7).
