The producing of metal match thing numerator sieve complex material belongs to the physical and chemical field. Its feature is using phosphorus acid aluminum numerator as the corpus, take the way of dipping to bring the metal ion into the phosphorus acid aluminum numerator, then match at some condition, so we fix the metal match things in the phosphorus acid aluminum numerator sieve. The producing way is simple and easy, has widespread applicability. What's more, we can control the producing condition; the complex material has different features. |
